The Installation Components

2.2.1

Loop Adaptor HG 94210

The loop adaptor is contained within an aluminium casing, size 120 x 122 x 91 mm. It 
is fitted with two PG plugs, one for the RG 213 coax cable from the generator and the

 

other for both ends of the loop conductor 2,5 mm². The casing should be earthed as

 

the voltage over-load is connected to it. 

The Coax Cable RG 213 should not be longer than 30 m and the loop conductor to the

 

guide wire should not be longer than 10 m in length.
