1.1 Overview
The AT Series Auto-Transfer Power Distribution Units (PDUs) provide automatic
transfer switching from primary (Source A) to secondary (Source B) in the event of
primary source failure. The PDU automatically transfers back to the primary source
when it becomes available. Front mounted LED’s indicate availability of power at
Source A and Source B. AT Series Auto-Transfer PDUs can optionally be configured
with a Geist Current Meter that provides local monitoring and display of each output
circuit current.

2 Installation
2.1 Instructions
1. Using appropriate hardware, mount PDU to rack (see Mounting section for
additional instructions).
2. Plug PDU into de-energized, Phase Synchronized branch circuit receptacles.
3. Connect devices into PDU’s output receptacles. It is recommended that the
devices are turned off until all devices are connected to PDU
4. Turn on branch circuit for Source A to energize PDU.
5. Turn on branch circuit for Source B.
6. Power on devices. Sequential power up is recommended to avoid high inrush
current.
2.2 Guidelines
Warning: Source power must be Phase Synchronized, high voltage potential may
result in relay failure when sources are not Phase Synchronized.
Some loads may pull high inrush current when switching power sources. Do not
overload ATS to prevent relay failure and tripping branch circuit protection.
If the PDU is installed in a cabinet the ambient temperature of the rack should be
no greater than 45 C.
Install the PDU such that the amount of airflow required for safe operation of
equipment is not compromised.
Mount the PDU so that a hazardous condition is not achieved due to uneven
mechanical loading.
Follow nameplate ratings when connecting equipment to the branch circuit. Take
into consideration the effect that overloading of the circuits might have on over-
current protection and supply wiring.
The PDU relies on the building installation for protection from over-current
conditions. A certified overcurrent protection device is required in the building
installation. The overcurrent protection device should be sized according to the
PDU’s nameplate ratings and local/national electrical codes.
Reliable earthing of rack-mount equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to
the branch circuit. The PDU must be connected to an earthed socket-outlet.
The PDU is intended for Restricted Access Locations only and only qualified service
personnel should install and access the PDU.
For pluggable equipment, install the PDU so that the input plug or appliance
coupler may be disconnected for service.
Sequential power-up of devices powered by the PDU is recommended to avoid
high inrush current.
Caution: Disconnect all power cords before servicing.
The PDU is intended for use with TN or TT power supply systems

4 Optional Local Monitoring
4.1 Power Meter
The Geist PM-1 power meter is a low-power, high accuracy meter capable of
measuring true RMS Current, Voltage, Power, and Power Factor. These values are
individually shown on an easy to read, 4-digit LED Display, which continuously scrolls
through the four different measured values. Each one of these displayed parameters
is defined below. The Power Meter will automatically begin cycling through the
displayed values when the PDU is connected to AC Mains power.
Current: PDU output current draw measured in true RMS Amps
Voltage: PDU output voltage measured in true RMS Voltage
Power: PDU output power measured in Watts – referred to as real or active
power
Power Factor: Ration of real PDU output power to apparent PDU output power

4.2 Current Meter
The Geist CM-1 current meter is a low-power, high accuracy meter capable of
measuring true RMS Current. The value of current is continuously shown on an easy
to read, 4-digit LED Display. The Current Meter will automatically begin to display
value of output current when the PDU is connected to AC Mains power.

5 Service/Tech Support
5.1 Service and Maintenance
No service or maintenance is required. Do not attempt to open the PDU or you may
void the warranty. No serviceable parts inside. It is recommended that power be
removed from the unit before installing or removing any equipment.
