Step Action Comment
1 Make sure the mains power supply in the shop
is working and that the voltage level matches
that of the controller requirement.
The installation documentation may
provide this as well as other vital
information.

correctly connected for the mains voltage level
at hand.
How to connect the transformer is found

3 Make sure the mains overload protection, FR1
has not tripped. If it has, reset it.
