5.4  Commissioning Procedure 

The  G1IF1  should  be  commissioned  in  conjunction  with  the  GRL100  relay  with  which  it  is 
specified. Refer to the GRL100 manual for full details. It is necessary to commission both ends of 
the protection scheme together. 

Ensure that all necessary communication connections are made at each end of the protection 
scheme. Apply auxiliary power to both GRL100 relays and to both G1IF1 units. Any failure in 
communication  will  be  indicated  by  the  GRL100  relays.  If  communication  is  healthy  then 
proceed with commissioning of the GRL100 relays. 

5.5  Maintenance 

Periodic maintenance is not necessary.
