4.3.2.  Mains Power Supply 
 
Before connecting electrical power to the repeater, it must be grounded. The repeater 
is equipped with a firmly connected mains cable which is fed into the housing through 
a watertight cable gland. Due to safety reasons, the power supply lead must be 
protected by fuses. Inside the repeater, the mains cable is connected to a screw 
terminal on the connecting board. In case the length of the power cable should not be 
sufficient, it can be replaced by a longer cable.
