EPO
Press the EPO (Emergency Power Off) button to switch off all AC and DC power
supply to connected equipment in the room. 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 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.
Note
CAUTION!
All wiring must be in accordance with applicable national and/or local electrical codes.
This unit contains components that are sensitive to electrostatic discharge (ESD).
Follow proper ESD procedures to avoid severe damage to electronic components.
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the Installation
Manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in which case the
user will be required to correct the interference at his own expense.

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 User Guide before
Note
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
Note
WARNING!
Supply the UPS from a dedicated, grounded, 3-wire Wye service.
CAUTION!
All wiring must be in accordance with applicable national and/or local electrical codes.
Use only UL-approved cable lugs.
Use only UL-approved cables. Use only stranded copper conductors. Refer to National
Electric Code for wiring and protection. Refer to bolt and lug table in the
“Specifications” section.
