The system is intended to be a complete power system in a box, so no connections need to be made
internally.
All the AC, DC (Load and Battery) connections are made at the rear of the unit.
Alarm connections are accessible from the front by pulling the Energy Manager forward.
The system is designed to be extremely simple to install and set up.
Note: This system is supplied with the AC and DC earths connected unless chassis DC isolation is specified when
ordering. The standard -48 VDC system output has the DC Common in the positive side of the circuit (+ve earth
system). On +24 VDC systems, the DC Common has the negative side of the circuit (-ve earth system) connected to
system chassis/earth. The earth link can be removed from the system to isolate earths
