DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Do not install the UPS system until all construction work has been completed
and the installation room has been cleaned. If additional construction work is
needed in the installation room after this product has been installed, turn off the

Electrical Safety
This manual contains important safety instructions that should be followed during
the installation and maintenance of the UPS system.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Electrical equipment must be installed, operated, serviced, and maintained
only by qualified personnel.
• Apply appropriate personal protective equipment (PPE) and follow safe
electrical work practices.
• Disconnection devices for AC and DC must be provided by others, be readily
accessible, and the function of the disconnect device marked for its function.
• Turn off all power supplying the UPS system before working on or inside the
equipment.
• Before working on the UPS system, check for hazardous voltage between all
terminals including the protective earth.
• The UPS contains an internal energy source. Hazardous voltage can be
present even when disconnected from the mains supply. Before installing or
servicing the UPS system, ensure that the units are OFF and that mains and
batteries are disconnected. Wait five minutes before opening the UPS to
allow the capacitors to discharge.
• The UPS must be properly earthed/grounded and due to a high leakage
current, the earthing/grounding conductor must be connected first.
Failure to follow these instructions will result in death or serious injury.
When the UPS input is connected through external isolators that, when opened,
isolate the neutral or when the automatic backfeed isolation is provided external to
the equipment or is connected to an IT power distribution system, a label must be
fitted at the UPS input terminals, and on all primary power isolators installed
remotely from the UPS area and on external access points between such isolators
and the UPS, by the user, displaying the following text (or equivalent in a language
which is acceptable in the country in which the UPS system is installed):
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Risk of voltage backfeed. Before working on this circuit: Isolate the UPS and
check for hazardous voltage between all terminals including the protective
earth.
Failure to follow these instructions will result in death or serious injury.

NOTE: Maximum short circuit rating: 10 kA RMS symmetrical.
For a 1+1 parallel system for redundancy, the parallel maintenance bypass panel
can support a load of up to 120 kW/kVA as long as the neutral current (250 A) is
not exceeded:
• at 380 V, the maximum neutral current capability is reached with a 95 kVA
non-linear load.
• at 400 V, the maximum neutral current capability is reached with a 100 kVA
non-linear load.
For a 2+0 parallel system for capacity, the parallel maintenance bypass panel can
support a load of up to 240 kW/kVA as long as the neutral current (500 A) is not
exceeded:
• at 380 V, the maximum neutral current capability is reached with a 190 kVA
non-linear load.
• at 400 V, the maximum neutral current capability is reached with a 200 kVA
non-linear load.
Recommended Upstream Protection
NOTE: For local directives which require 4-pole circuit breakers: If neutral
conductor is expected to carry a high current, due to line-neutral non-linear
load, the circuit breaker must be rated according to expected neutral current.
