To remove PEM nuts:
1. Place a 9/16" socket over the PEM nut to be removed.
2. Insert a 3/8" bolt through the socket and thread into the PEM nut.
3. Using a socket wrench with a 9/16" drive, tighten the head of the bolt until the action pulls the
PEM nut from the bus bar.

5.4.2 Load Distribution
Refer to guidelines supplied with the load equipment. Typically distribution cables are sized to provide a 0.5 V
loop drop at full load as well as meeting ampacity requirements of the protection fuse or circuit breaker.
5.4.2.1 AM Breakers
The CXPS 48-2T is factory configured with (38) total single-pole AM-type plug-in breaker
positions for 48V load distribution. The breakers have bullet terminals, which plug into the
breaker tier for simple installation and removal. Each distribution tier has a 1/4” – 5/8”C hole set
for the breaker output and on the ground bar located directly above the breaker panel.
• 1 to 100 amp breakers require 1 position.
• 110 to 150 amp breakers require 2 positions*.
• 175 and 200 amp breakers require 3 positions*.
* 2-position and 3-position breakers have an output adapter that provides a single 3/8" hole on a 1" center output.
The return must use one of the battery or rectifier terminations.

It is recommended to install the largest capacity circuit breakers on the top distribution tier to
optimize cable management. It is imperative to plan circuit breaker installation to allow for
