12.0 Commissioning

12.1 Connecting the Mains

Important Note:

• Pay particular attention that the earth cable is firmly connected to the earth terminal of the

power supply, and that the earth strap from the power supply PCB to the earth post is

sound.

Ensure the fused double pole isolator is in the ‘OFF’ position then connect the incoming mains cable

to the appropriate terminals on the power supply PCB (see figure 12.0).
