A severe shock hazard exists.
The ONLY user serviceable items in the MGE Galaxy 4000 unit are:
A
The main and bypass power connections.
B
The load connection.
C
Any cable connection to external or auxiliary modules.
D
The communication card options.
The access method for connections made to the communication cards is clearly seen when the front
right door to the MGE Galaxy 4000 unit is opened. However, access to the main, bypass and load
connections is made through the removal of the safety panel located in the lower right of the MGE
Galaxy 4000 (with the right door open). This safety panel is removed by rst removing the screws
securing the panel. It can then be removed by lifting the safety panel away from the unit.
Caution: Before making any electrical connections, verify that all battery disconnect
circuit breakers (QF1) are in the "off" position. Customer-supplied upstream protective
devices and distribution circuits should be OFF.
