3.2.4. Mains Power Connection
Before connecting electrical power to the units, the system must be grounded
(earthed) as described in the previous chapter.
The Mains power must be connected to the Mains connector of the unit for operation
of the RU. A power cable is delivered with each RU. The type of power cable
delivered is dependent on the type of power supply in the RU.
The AC power cable is a 3.2 m (10.5 ft) 16 AWG cable with a 4-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 3 end splices to connect to the AC power source. A 10 m
(33.7 ft) AC power cable (part no. 7573605-00) is also available as an option. The AC
power cable is shown in figure 3-10.
