MGC Hardware and Installation Manual

MGC Manager Interface

As shown in Figure 3-4, “MGC unit functional block diagram” on page 3-4, the Main Control Unit communicates with the MGC Manager through the LAN interface or the RS-232 interface.

Power Supply Flow

For the MGC-100, the AC power inlet is connected by a switch through a 15 Amp. circuit breaker and then filtered to the AC power supply module. The DC power outlet delivers 5V, 12V, and -12V through the power bus in the Backplane to the functional units and the Main Control Module. The 12V is also delivered to the fans.

For the MGC-50, the AC power inlet is connected through a 12.5 amp. 250 volt fuse and then filtered to the AC power supply module.
