exists which will result in personal injury if the instructions are not followed.
This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all
safety messages that follow this symbol to avoid possible injury or death.
DANGER
DANGER indicates an imminently hazardous situation which, if not avoided, will result in death
or serious injury.
WARNING
WARNING indicates a potentially hazardous situation which, if not avoided, can result in death
or serious injury.
CAUTION
CAUTION indicates a potentially hazardous situation which, if not avoided, can result in minor
or moderate injury.
NOTICE

hazards, potential damage or loss of data.
InRow RC Installation Manual6
Safety Notices During Installation
Read and adhere to the following important safety considerations when working with this equipment.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical work
practices. See NFPA 70E or CSA Z462.
• This equipment must be installed and serviced by qualified personnel only.
• Turn off all power supplying this equipment before working on or inside the equipment.
• Always use a properly rated voltage sensing device to confirm power is off.
• Replace all devices, doors, and covers before turning on power to this equipment.
Failure to follow these instructions will result in death or serious injury.
WARNING
HAZARD OF EQUIPMENT FALLING OVER
• Use two or more persons at all times to move or turn this equipment.
• Always push, pull, or turn while facing the front and rear of this equipment. Never push,
pull, or turn while facing the sides of this equipment.
• Slowly move this equipment across uneven surfaces or door thresholds.
• Lower leveling feet to floor when this equipment is at rest.
• Lower leveling feet and attach joining brackets to adjacent racks when this equipment is
in final position.

Pre-Installation
Room preparation
During the design of the data center, consider ease of entry for the equipment, floor loading factors, and
accessibility to piping and wiring. In addition, the room temperature and humidity combination should conform
to the environmental operating envelope as defined in the following graphics.
Seal the room with a vapor barrier to minimize moisture infiltration. Polyethylene film is recommended for
ceiling and wall applications. Apply rubber- or plastic-based paints to concrete walls and floors.
Insulate the room to minimize the influence of exterior heat loads. Reduce fresh air to the minimum required by
local and national codes and regulations. Fresh air imposes extreme load variation on the cooling equipment
from summer to winter and causes increased system operating costs.
Air distribution
The equipment distributes air in a back-to-front discharge pattern, removing hot air from a hot aisle and
discharging cooled air into a cold aisle.
NOTE: The equipment is designed for free air discharge or for use with the Rack Air Containment System or
Hot Aisle Containment System. The equipment is not intended to be connected to a duct system.

Automatic transfer switch (ATS)
The function of the ATS is to transfer load from feed A to feed B if
the power is lost on feed A.

Humidifier (ACRC60xP units only)
The humidifier water supply line is routed to the unit in flexible tubing (or alternative tubing
approved by local building codes) that will allow the humidifier water supply line connector
to be moved approximately 25 mm (1 in.) away from the equipment. This facilitates
removing the equipment from a row.
A factory-installed quick-connector for connecting the tubing to the equipment is supplied.
The quick connector has a male 1/4-in. NPT or male 1/4-in. BSPT to connect to a
compression fitting. The quick-connector has a shut-off function, so no separate shut-off
valve is necessary.
The humidifier water supply line can be
connected through either the top or the
bottom of the equipment as shown. Male
quick-connectors are positioned in both
the top and the bottom of the equipment.
Water pressure should be between 100
and 800 kPa (15 and 115 psi) for proper
humidifier operation. Dirty water must be
filtered before it is supplied to the
humidifier. Water temperature must be
between 1°C and 40°C (34°F and
104°F). Do not use softened,
de-mineralized, or de-ionized water.
See the manual included with the humidifier for more information about water quality, mineral
content, hardness, and minimum/maximum levels for conductivity.
NOTE: Before making any connections, clear any debris that may have accumulated during assembly from the
humidifier water supply line.
NOTE: It is recommended that a solenoid water valve be installed in the humidifier supply line, connected to a
leak detector.
NOTE: Perform all piping in accordance with applicable industry guidelines as well as local and national codes
and regulations.
Connect the fittings to the humidifier water supply line as shown, then connect the water
supply line quick-connector to the top or bottom humidifier input.

Rack temperature sensors
The rack temperature sensors control the equipment airflow and ensure adequate supply of cooling air to the
server racks in the data center.
The equipment is supplied with three external rack temperature sensors.
See “Install kit inventory” on page 10. These sensors, along with cable ties
and wire clips, are included in the installation kit shipped with the
equipment.
How to install the rack temperature sensors
1. Insert the rack temperature sensor connector in the temperature sensor port customer interface
connections. See “Customer interface connections” on page 39.
a. For a top installation, push the rack temperature sensor
through the wire channel located at the top of the
equipment in the left hand side just above the customer
interface connectors.
b. For a bottom installation, route the sensor through the
wire clamps along the electrical panel and then push
the sensor through the customer access hole in the
bottom of the equipment.
2. Route the sensor through either the top or the bottom of the
adjacent server rack.
3. Secure the temperature sensor cable to the front door of the
adjacent server rack at multiple locations using the provided
wire clips as shown. See “Install kit inventory” on page 10.
NOTE: Remote rack temperature sensors must be installed
for proper operation.
The sensors should be located on racks that are adjacent to the cooling unit. The optimum position of
the rack temperature sensors will vary from installation to installation but should be located in close
proximity to fan-cooled IT equipment to ensure accurate readings.
Servers most likely to have insufficient or inadequately cooled air due to the recirculation of hot air from
the hot aisle include the following:
a. Servers positioned at the top of a rack
b. Servers positioned at any height in the last rack at an open end of a row
c. Servers positioned behind flow-impairing obstacles such as building elements
d. Servers positioned in a bank of high-density racks
e. Servers positioned next to racks with Air Removal Units (ARU)

Water outlet temperature sensors
There are two water outlet temperature sensors, one for top

are wired to the main board on the electrical panel.
The unit is delivered with top connection as the default
configuration, i.e., the wire with a green tie wrap is positioned
in connector J23 (marked with green) on the main board. If
the configuration is changed from top to bottom, switch the
wire already positioned in the connector J23 with the wire
labeled with a green and a white tie wrap. This wire is part of
the wire harness inside the electrical panel.
Communication connections
A-Link connections: The A-Link bus connection allows communication between cooling units. Only one
InRow RC unit needs to be defined through the display. The numbering of the other InRow RC units (up to a
maximum of twelve) will take place automatically.
To enable the equipment to work as a group, link the units using the supplied cables or CAT-5 cables with
RJ-45 connectors as shown. Terminators (120 Ohm, 1/4 W) must be inserted into the open A-Link ports at the
first and last InRow RC unit.
The maximum wire length for the entire group may not exceed 1000 m (3,280 ft).
