The Vdc/100 power cable is available for locations where the power drawn on each

cable must be limited to a maximum of 100 VA. This cable is a 3.2 m (10.5 ft) 16

AWG cable with a 7-pin Amphenol C016 series plug on one end to connect to the RU

Mains connector. The other end of the cable is un-terminated with 4 end splices to

connect to the -48 Vdc power source.

For the AC power supply connection, a minimum cross section of 1.5

is required and for the DC power supply connection, a minimum

cross section of 2.5 mm

is required. Each wire must observe the

applicable national regulations regarding loop impedance, voltage drop,

and methods of installation. Make sure to connect the correct voltage to

the unit.

 Note: Do not connect or disconnect the power cable at the mains

connector while power is on. Turn off mains* power before

connecting the power cable at the remote unit, then, engage mains

power again.

* Mains power must be interruptible with an external mains breaker. For the

mains breaker, observe the following recommendation:

120 Volt / 20 Amp max. or 240 Volt / 16 Amp, single-phase, 50 / 60 Hz AC

service is needed, i.e. the external AC breaker should be 20 Amps max. for

120-Volt service or 16 Amps for 240-Volt service.

For the DC power supply, observe the local regulations of the DC service

provider.
