Z -RANGE INSTALLATION MANUAL
Communication
The communication cables start from the master unit’s Link A port to Link B on the second
unit. This A -> B loop continues, in sequence, up to the last unit. No termination plug is
necessary on the final Z-Range unit. Figure 6 shows the connection of the communcation
cables between the batteries.

Wiring methodology #2:
Daisy chain the DC connections, from bottom to top. This wiring methodology limits the
current output to the maximum recommended output of a single battery, but increases the
available capacity. Figure 5 illustrates how to connect the batteries with this method. For this
configuration we recommend that the provided cable from the master box be connected
to the top unit and the DC disconnect. The interconnecting cables can be made from the
other batteries’ DC cables by cutting the lug side cable, and crimping the provide amphenol
connecter. The recommended length of this interconnecting cable is 150 mm.
