Connecting the Power Supply
● Main power
Caution
z Use an AC outlet capable of supplying AC 100 to 240 V at 50 or 60 Hz.
1 Insert the socket of the provided AC power cord into the AC IN jack at the rear of the repeater
2 Insert the plug of the provided AC power cord into the AC outlet
● Backup power
For uninterrupted operation during power failures, a 13.8 V rechargeable automotive type battery (55-Ah or more recommended) may
be connected to the BACKUP terminal posts on the rear panel. In the event of an AC power outage, the automatic power control circuit
will automatically switch the repeater to the backup battery, and operation will not be interrupted.
If the power is out for a long time, the battery may be completely discharged. When the power is restored the DC startup current may
blow the protection fuse. So the protection fuse in charge circuit should be checked after an outage.
While operating from a battery or DC supply, the repeater requires approximately 14 A at 13.8 V during transmit.
Follow the outline in the illustration regarding the proper connection of the DC power cable.
Always observe proper polarity when making DC connection.
Cautions
z Use a power source capable of supplying DC 13.8 V and a current capacity of 14 A or more.
z Make sure to switch OFF the power of the external power source before connecting.
1 Insert the socket of the provided DC power cord to the BACKUP jack at the rear of the repeater
2 Connect the red wire (+) of the provided DC power cord to the positive (+) terminal of the external power source, and the black wire
(-) to the negative (-) terminal
