Note that during battery operation with AC power off the front panel display
and optional external communication ports will not be powered. Only the
battery LVD circuitry will be active.

Installation
The ICT Digital Series Power Supply is designed to be used in an industry
standard 1RU 19” rack mount cabinet or other restricted access location.
Insert the unit at the desired rack location, and secure the unit using standard
rack nuts and bolts (not provided). After the unit is mounted, connect load
and supply wiring as outlined in the steps below, referring to the back panel
drawing in Figure1 for connector locations:
(Figure 1 - Back Panel, “SBC” model shown)
1.
Connect the positive side of the load to the ”POS” busbar and
the negative side of the load to the ”NEG” busbar using
suitable wire and supplied hardware. Make sure to tighten the
busbar hardware to properly secure the wires.
2.
If applicable, on units with the Battery Backup (LVD) option
installed connect the POSITIVE of the backup battery to the
“BAT” busbar and the negative of the backup battery to the
“NEG“ busbar using suitable wire, over current protection,
disconnect device and hardware.
CAUTION!
The internal LVD contactor ties the “BAT” terminal to the power
supply “POS” output
.
When using the LVD option in a positive ground system do not
ground the positive terminal of the battery. The system must only
have a single ground connection, normally located at the distribution
or load point. An additional ground connection at the battery will allow
current to bypass the internal LVD contactor preventing
disconnection of the battery during a low voltage event.
