Safety: IMPORTANT SAFETY INSTRUCTIONS - SAVE THESE INSTRUCTIONS

Installation safety

Press the optional EPO (Emergency Power Off) button to switch off all AC and DC
power supply to connected equipment in the room and to cut off the load supply. The
EPO
EPO is typically located on a wall in the room in which the UPS is installed. See
“Communication cable overview” section for information on how to wire the UPS to
the EPO.
WARNING!
Before starting installation, check and test that all AC and DC power source
breakers are in open position.
WARNING!
Only personnel trained in the construction and operation of the equipment, and the
electrical and mechanical hazards involved, may install or remove system
components.
CAUTION!
Do not use High Voltage Testing Equipment. This equipement will destroy the
electronic circuits in the unit.
CAUTION!
The system is equipped with an optional auto-start function, enabling the system to start
without any warning when power is applied.
CAUTION!
All wiring to be in accordance with applicable national and/or local electrical wiring
rules.
This unit contains components that are sensitive to electrostatic discharge (ESD).
Follow proper ESD procedures to avoid severe damage to electronic components.

Electrical Installation: Electrical Wiring Principle

External disconnection switches

WARNING!
The UPS has no internal manual disconnect devices to switch off external AC (Q1
and Q5) and DC (Q7 and Q8) input power. Ensure that disconnection devices are
available as separate components for this installation.
The installer must provide each external disconnection device for this UPS system with
labels displaying the following text:
“Isolate the Uninterruptible Power Supply (UPS) as instructed in the Operation Manual
Note
before working on circuit.”

Input/Output wiring precautions

WARNING!
Only personnel trained in the construction and operation of the equipment, and the
electrical and mechanical hazards involved, may install or remove system
components.
Note
WARNING!
Before starting installation, check and test that all AC and DC power source
breakers are in open position.
WARNING!
Supply the UPS from a 3 × 400/230 V, L1, L2, L3, N, PE source or a high-impedance
grounded system.
CAUTION!
All wiring to be in accordance with applicable national and/or local electrical wiring
rules.
Use only copper conductors.
