Installation safety

Press the optional EPO (Emergency Power Off) button to switch off all AC and DC power

EPO

supply to connected equipment in the room and to cut off the load supply. The 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 you start the installation, verify that all AC and DC power source breakers are in the open position.

Warning: Only personnel trained in the construction and operation of the equipment, and the electrical and mechanical hazards involved, must install or remove system components.

Warning: Do not use high voltage testing equipment as it will destroy the electronic

circuits in the units.

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.

System Overview

UPS Sections

The UPS system consists of two 600 kW Inverter Sections, a Control/Input/Output Section and an External Bypass Static Switch Section.

Serial number

The serial number is stated on the type label behind the finishing panel above the display unit. Remove finishing panel as described in “Appendix C” to see serial number.

Inverter Section

The Inverter Sections regulate the UPS output and operates from battery power in the event of mains input loss.

Control/Input/Output Section

The Control/Input/Output Section controls and monitors the UPS and contains the input/output terminations.

External disconnection switches

Warning: The UPS has no built-in disconnect devices to switch off external AC (Q1 and

Q5) and DC (Q7 and Q8) input power. Ensure that the disconnect devices are available as separate components for this installation.

Note: The installer must provide each external disconnect device for this UPS system with labels displaying the following text: “Isolate the Uninterruptible Power Supply (UPS) as instructed in the User Guide before working on the circuit.”

Input/Output wiring precautions

Warning: Only personnel trained in the construction and operation of the equipment,

and the electrical and mechanical hazards involved, must install or remove system components.

Warning: Before you start the installation, verify that all AC and DC power source breakers are in the open position.

Warning: Supply the UPS from a 3 × 400/230 V, L1, L2, L3, N, PE source or a highimpedance grounded system.

Caution: All wiring to be in accordance with applicable national and/or local electrical wiring rules.

Note: Use only copper conductors.
