Alternate wire gauges may be used for the DC feeders, but shall be sized
to limit the round trip voltage drop between the power system output
terminals and the Modular Cell input terminals to less than one volt (for
+24 VDC systems).
A current level equal to 80% of the circuit breaker current rating
specified shall be used for this calculation. The wire used for the DC
feeders shall be rated for the environmental condition in which it is used
and shall be rated and sized according to the applicable section in the
National Electrical Code or Canadian Electrical Code, Part I (NAR
markets) and IEC 60364, or the local electrical code in effect
(international markets). The circuit breaker shall be type 51 with DC
trip-delay curve characteristics. The DC power terminal block is located

Observe safety
considerations The safest condition for installing and connecting the dual band cabinet
is with the system de-energized. If a dual band cabinet is to be added to
an operating system, the owner/operator of the system must be
consulted. The owner/operator must provide approval as to whether
and when the system will be fully or partially de-energized. The
customer may request that the work be performed while the system is
energized. If so, observe the following caution.
DANGER
Electrical Shock Hazard
Installation of a Modular Cell 4.0B dual band cabinet
requires DC connections to be made in the non-Lucent power
source with AC power on (unless the installation is performed
during a maintenance window that allows AC power to be
turned off at the main panel and the batteries disconnected).
The procedures in this manual do not include safety
procedures regarding working on energized equipment. When
this manual is used to install equipment in an energized
system, the appropriate safety procedures must be followed in
addition to the procedures in this manual. Failure to follow
the order of the installation procedure (as written) can create
an electrical shock hazard.

Description of the AC
power cables The installation requires the following AC power cable or cables.
• #10 AWG 3-wire - for the heaters
• #14 AWG 3-wire - for the convenience outlet, if applicable (not
present in international cabinets).
DANGER
Electrical Shock Hazard
Installation of the Modular Cell 4.0B cabinets require
connections to be made that require AC power to be turned off
at specific circuit breakers in the non-Lucent power source.
Failure to follow instructions to turn off these breakers can
create an electrical shock hazard. Failure to follow the order
of the installation procedure (as written) can also create an
electrical shock hazard. The procedures in this manual do not
include safety procedures regarding working on energized
equipment. When this manual is used to install equipment in
an energized system, the appropriate safety procedures must
be followed in addition to the procedures in this manual.
Follow these rules:
1. Perform installation steps in the order provided.
2. Observe and strictly follow all safety precautions.
3. When completing electrical connections, always use
tools that are properly insulated.
