Wiring
Refer to Table 1 in "Overview" for details regarding the
Installation and Startup Package, which is used to simplify setup
and installation of the UPS.
Code Compliance Information
WARNING: The UPS requires a direct connection to a dedicated
AC branch circuit (AC mains). Connection should only be
performed by a qualified electrician in accordance with National
Electrical Code (NFPA 70) Article 310 in North America or in the
equivalent local and national wiring regulations.
WARNING: If the UPS is to be installed in a server equipment
room, it must be connected to a REPO circuit. The REPO port is
designed to meet the requirements stated in National Electrical
Code (NFPA 70) Articles 645-10 and 11.

Connecting the REPO Port

The UPS includes a REPO port. When properly wired, the REPO
port allows the power at the UPS output receptacles to be switched
off from a remote location. Local or national wiring regulations
may require REPO capabilities.
WARNING: To reduce risk of personal injury or damage to
equipment, the REPO port must be wired by a qualified
electrician.
WARNING: Remote circuits connected to the REPO port must
comply with local building wiring codes and methods. In North
America, the National Electric Code (NFPA 70, Article 725) is a
minimum requirement.
The UPS REPO circuit is an IEC950 Secondary Extra Low
Voltage (SELV) circuit. The computer room Emergency Power
shutdown circuit conductors that connect to the REPO terminals
must meet the requirements of an NEC Class 2 circuit or an
IEC950 SELV circuit and must be separated from any hazardous
voltage circuits or conductors by reinforced insulation.
The server room Emergency Power shutdown circuit must:
• Short the UPS REPO terminals.
• Disconnect the UPS AC input source.
WARNING: To avoid risk of personal injury or electric shock,
verify that the main breaker switch is in the Off position before
wiring the REPO port.
To connect the REPO port to the EPO circuit:
1. Verify that the UPS is disconnected from utility power.
2. Connect the switch or circuit to the REPO port.
IMPORTANT: The cable that connects the UPS to the REPO port must be
UL Listed, of type CL2, CL2P, CL2R, or CL2X, depending on the
requirements of the local installation.
3. Verify that the Remote Circuit is off. Be sure the REPO switch
is in the Off (open) position to enable power to the UPS output.
Connecting the Ground Bonding Screw
The ground bonding screw on the rear of the unit is provided as an
attachment point for conductors. Use the ground bonding screw if
the rack contains any conductors for the purpose of functional
grounding or bonding of ungrounded metal parts.
To connect the ground bonding screw:
Remove the ground bonding screw nut (1), attach the grounding
cable, and secure the ground bonding screw nut (2).
