9.6 Electrical Installation
It is recommended that mains cables are fixed first to avoid damage to aerial or signal cables.
If the FEC RLC is to be operated from a mains power supply it must be connected to the supply
using a fused double pole isolator.
The controller has a maximum power consumption of 30watts so if the supply is only powering the
controller (the switched circuits being separate) then a 5 Amp fuse should be used.
If the same supply is to be used both to power the controller and the switched circuits then the
cable, switch and fuse rating need to be sized accordingly.
WARNING
– If the circuits to be switched are fed from a separate isolator it is imperative that this
is also isolated before work is commenced.
