AT THE MAINS.

The cable can be surface clipped, hidden or
via 20mm conduit. For this handwash unit the
minimum cable size will be 1.5mm².
The supply cable earth conductor must be
sleeved. The outer sheath of the supply cable
must be stripped back to the minimum. For top
cable entry, remove sufficient outer sheath to
assist routing beneath and looping back into the
terminal block - DO NOT remove too much.
Conduit entry can only be from rear. Route the
cable into the unit and connect to the terminal
block (
fig.9
) as follows:
Earth cable to terminal marked
Neutral cable to terminal marked N
Live cable to terminal marked L
IMPORTANT
: When connecting the cable, fully
tighten the terminal block screws and make sure
that no cable insulation is trapped under the
screws - loose connections can result in cable
overheating. Make sure the cable is fully secured
by the cable clamp provided (
fig.10
). If top
entry is used, move the cable clamp from its
position at the bottom entry position to the top
entry position.
The use of connections within the unit, or other
points in the circuit, to supply power to other
equipment i.e. extractor fans, pumps etc. will
invalidate the guarantee.
DO NOT switch on the electricity supply
until the cover has been fitted and the unit
commissioned.
