CONNECTIONS AND MAINTENANCE
n Power supply connections
CAUTION: IC-GM651 should be connected to the DC
power supply through the PS-250
sold by the set with the IC-GM651, when it is operated.
Before connecting the DC power cable, make sure the
power is OFF, and the DC power cable polarity is correct.
• Red : positive + terminal
• Black : negative − terminal
BE SURE to connect the supplied DC power cable only,
and DO NOT extend the cable length.
The PS-250 -
dc dc power supply
IC-GM651, converts the input voltage (10.8 to 31.2 V DC)
from the DC power supply, then provides 12.5 V DC, 5.3 A of
the continuous power to the transceiver.
The optional PS-240
voltage (85.0 to 264.0 V AC: 47 to 63 Hz; nominal operating
frequency 50 Hz) from the AC outlet, then provides 14.5 V
DC, 7 A of the continuous power to the PS-250.
