MAINS CONNECTIONS
Do not connect the mains supply to the panel
until you are fully conversant with the layout
and features of the equipment.
A rating plate is attached to the power supply
module describing the nature of the supply
permitted.
The incoming mains supply should be brought
into the panel via one of the knockouts
provided.
A suitable cable gland must be used to secure
the outer sheath of the cable used. The earth
must first be connected to the primary earth
stud (peg) marked with a symbol, using a
suitable ring crimp.
Sufficient earth lead should be left to allow Live and Neutral connections to be accidentally pulled from the
terminal block while leaving the earth connection intact.
