Installation
To wire the MS-CEFB fi lter box to the battery bank:
1. Route the end of the positive DC battery cable from the battery bank
through the supplied red DC terminal insulator (do the same for the nega-
tive DC cable – using the black DC terminal insulator). The insulators pro-
tect the MS-CEFB’s DC terminals and can help prevent accidental shorts.
WARNING: Before connecting the DC cables from the battery bank
to the MS-CEFB, ensure DC overcurrent protection has been installed
and the correct DC voltage and polarity have been verified.
2. Connect the positive and negative battery cables to their respective termi-
nal posts on the front of the fi lter box. When connecting the battery cables
to the fi lter’s DC terminals, the cable’s ring lug should be placed directly
against the fi lter terminal (Figure 8). Torque to 20.4 N-m (15 ft lbf).
3. Fit the red and black DC terminal insulators (that were routed over the
DC battery cables in Step 1) over their respective terminal posts.
WARNING: DO NOT close the DC circuit breaker or connect the fuse
to bring battery power to the inverter at this time. This will occur
in the Functional Test after the installation is complete.
Info: Refer to your inverter owner’s manual for the required DC
wiring sizes and overcurrent protection.

Communication Cables
When connecting a communication cable (remote, network, stacking or BTS)
to the inverter, a ferrite core must be connected to one end of the cable. A
ferrite core is shaped like a metal doughnut and is a passive electronic com-
ponent used to suppress high frequency noise in electronic circuits. It is used
to reduce EMI that may be transmitting, and prevents the cable from acting
as an antenna and receiving interference from other devices.
Info: The BTS cable and another communication cable (e.g., remote
cable) can both fi t and be separately wrapped three times into a sin-
gle ferrite core. However, if using more than one cable with a single
ferrite, all must go in the same direction around the core.
