Installing Circuit Breaker Cover for DC PEMs
The circuit breaker cover (PN 0706820C11*) is included with the Centellis 2000 DC systems
and replacement DC PEM. The use of circuit breaker cover is optional. The purpose of the cover
is to prevent the shut down of the PEM when the PEM power switch is accidentally hit. When
the cover is placed over the PEM power switch, the ON side is accessible with a person's finger,
but the OFF side is accessible only through an access hole (approximately 6X9MM) that
requires a small screw driver or stick to trigger.
Installing Procedure
The cover is positioned over the circuit breaker switch and attached to the DC PEM
using the two existing screws of PEM.

When installing the cover, make sure to remove only one screw at a time so that the circuit
breaker switch does not get pushed into the PEM.
