Power Installation

The Power Supply Circuit of the MBU provides power for the system boards and telephones, converting the AC Input Voltage to appropriate DC voltages. Before installation, assure that the AC power cord is NOT plugged into the AC INLET. The Power Supply Circuit is located on the left upper side of the MBU.

The GDK-20W Power can only operate 220~240V AC based on the connection of the cable(4-wired) by the CN22 from transformer and the connection of the cable(2-wired) by the CN21 to transformer.
