b) The keyswitch assembly may be mounted on a
standard electrical box or on the backbox.
c) Feed the fire rated cables through the entry holes and
mount an electrical box or the red/blue back box to an
even wall surface using suitable fixing.
"When semi flush fixing the keyswitch
assembly a standard electrical box must first be flushed
into the wall before the keyswitch assembly is fitted.
d) Terminate each cable entry at the
back box. Use the earth strap or
the earth point in the back box to
maintain loop cable earth
continuity. Connect the loop cable
to the terminals.
e) Disengage front cover from the
keyswitch assembly using the end of the opening key
'E' and lift out the cover from the bottom edge.
f) Secure the keyswitch assembly to the back box using
the 2 long screws supplied.
g) Hook the front cover onto the top edge of the
keyswitch unit and then push the bottom edge down
until it click shut. Check both hooks on the top of the
front cover are locked onto the keyswitch assembly.
Operation
To operate the keyswitch insert the operating key into the
keyhole 'J' and turn clockwise to the stop position, the red
LED 'K' is flashing. The green LED 'I' gives an operating
indication.
Apply the reverse procedure to return the keyswitch to a
normal operating position.
Label
When using the blue keyswitch interface to control plant
ensure the unit is labelled to describe what is being
controlled by the keyswitch.
It is suggested that an A4 sheet white paper label
32 x 12mm is used, such as the one from RS, part number
RS495 385. The required text can be printed onto the label.
The label is stuck centrally inside the aperture behind the
transparent cover. Ensure LEDs remain visible and are not
covered by the label.
