Completing the installation
To complete the installation of the UPS, complete the following steps:
1. If you are installing the IBM UPS Manager software, connect a computer to the
UPS by using one of the communication cables that come with the UPS. For
more information, see “Installing the UPS Manager software” on page 43.
2. If the rack cabinet has conductors for grounding or bonding of ungrounded
metal parts, connect the ground cable (purchased separately) to the ground
bonding screw. For the location of the ground bonding screw, see “Rear view of
the UPS” on page 9.
3. If an emergency power-off (disconnect) switch is required by local codes, see
“Installing the remote emergency power-off” on page 14 to install the remote
emergency power-off switch before you turn on the UPS.
4. Connect the devices that you want to protect to the applicable UPS output
receptacles. Do not turn on the devices. For information about load segments,
see “Configuring load segments” on page 38.
Chapter 2. Installing the uninterruptible power supply 13
Notes:
1. Do not protect laser printers with the UPS because of the exceptionally high
power requirements of the heating elements.
2. Before you connect the UPS power cord to a power source, see “UPS initial
startup” on page 25.
Installing the remote emergency power-off
The UPS includes a remote emergency power-off connector that enables you to
turn off power at the UPS output receptacles from a customer-supplied switch in a
remote location. For example, you can use this feature to shut down the load and
the UPS by thermal relay, in the event of a room overtemperature condition. When
a remote emergency power-off is activated, the UPS shuts down the output and all
its power converters immediately. The UPS logic power remains on to issue an
alarm.
The remote emergency power-off feature shuts down the connected devices
immediately and does not follow the orderly shutdown procedure that is initiated by
any power-management software.
Any devices that are operating on battery power are also shut down immediately.
When the remote emergency power-off switch is reset, the connected devices do
not return to battery power until the UPS is restarted manually.
Notes:
1. The remote emergency power-off contacts are open by default. To change this
setting, see the REPO setting in Table 8 on page 32.
2. For Europe, the emergency switch requirements are detailed in Harmonized
document HD-384-48 S1, “Electrical Installation of the Buildings, Part 4:
Protection for Safety, Chapter 46: Isolation and Switching.”

Wire function Terminal wire size rating Suggested wire size
2
Remote emergency power-off 4 - 0.32 mm
(12 - 22 AWG) 0.82 mm2(18 AWG)
3. The pins must be open to keep the UPS running. If the UPS shuts down
because the remote emergency power-off connector pins are shorted, restart
the UPS by reopening the remote emergency power-off connector pins and
turning on the UPS manually. Maximum resistance in the shorted loop is 10
ohm.
4. To avoid accidental load loss, always test the remote emergency power-off
function before you apply your critical load.
