We recommend completely wiring all module positions at this time. Modules can be connected to
individual feeders or with a single feed (3 phase or 1 phase) which is than branched to each mod
-
ule terminal block using an appropriate in-line wire connector such as a split bolt or swage splice. If
the modules are to be connected to a 1 phase feeder they should be connected as shown in Figure
#8 . If the modules are to be connected to a 3 phase feeder they should be connected in a DELTA
configuration as shown in Figure #9 . When using a 3 phase feeder, 3 connected modules are rec

ommended to give a balanced load; a 4th module can be added but it will cause a load imbalance
depending on the current drawn. It is recommended to use individual feeds and feeder breakers if
possible for optimum reliability. The 3 x 1/2" knock out plate and the 7 x 1/2" knock out junction box
facilitates the installation of individual feeds. Use of a flexible conduit for the feeder wires is recom-
mended.
If a cable knock out plate is used, re-attach it to the shelf chassis using the two Philips head screws
provided.
WARNING: D.C. power may be present across the output terminals
from a connected battery or parallel unit even if the output breaker is
open. :WARNING

made. :WARNING
Users of this equipment should be aware of the short circuit current capacity of the connected bat

tery system in relation to the interrupting capacity of the output breaker. In applications where the
battery system short circuit current may exceed the breaker's interrupting capacity, the battery ca

bles should be protected by a high interrupting capacity fuse or breaker. The current limiting capac

ity of the battery system can be aided by selecting the minimal wire size without compromising the
maximum loop voltage drop.
