INSTALLATION
4.3.5 Control Wire Connections
The control wire connections should be made between the UPS Battery Cabinet and the
UPS cabinet as indicated in Figure 4–3 and Figure 4–4. Control wire connections are
made inside the rear, top left portion of the UPS Battery Cabinet (Figure 4–4). These
wires with terminal connectors attached must be provided by the customer’s electrician
and should meet all local and national codes. It is recommended that conductors with an
insulation value of 600 V or greater be used.
The control wires may need to be run in a separate conduit from the power and ground
wiring. Consult local codes for resolution.
4.3.6 Interbattery Link Connection
Connect the interbattery link(s) located at the front of the pull-out rack assembly. This
link(s) was removed for shipment of the UPS Battery Cabinet to your site. The link is
strapped in place adjacent to the batteries to be interconnected. These connections should
be torqued to meet the initial torque value requirements in Table 4–3.
