AC MAINS
Warning
– ensure that the mains supply is
switched off at the source before starting
work.
Warning
– risk of electric shock. Do not
remove the cover plate unless the mains
supply has been disconnected.
The mains connection to the Intellivox should
incorporate a manual circuit breaker or an
accessible mains plug.
Warning
– this apparatus is a Class 1 device
and must be connected to a mains socket outlet
that provides a safety ground connection.
Warning
– the presence of mains voltage is
not indicated by the front panel LED or the LED
display on the input module. These indicate
the status of the Intellivox and cannot be used
as a mains voltage indicator.
To make the AC mains connection, proceed as follows:
1. The mains connector can be accessed through the rear
connection panel. Remove the rear cover plate to access
the input board.
2. The mains cable should be routed through the right
hand 25 mm hole. To maintain the Intellivox’s IP rating,
this hole must be fitted with a gland of the correct size
for the cable, or flexible conduit.
3. Strip the ends of the cable.
4. Fit the female 3-pin, 7.5 mm-pitch screw terminal
connector supplied with the unit. The connector should
be wired as per the table below:

Fit the lower half of the connector cover to the connector,
ensuring that the cable’s outer insulation (not the three
inner wires) is firmly retained under the strain relief bar.
Clip the upper half of the cover in place.
5. Plug the wired connector into the male
Mains In
connector on the PCB. Fit a cable tie to the right-hand
cable tie base immediately behind the male connector
to provide strain relief.
Note that the safety regulations applicable to
this equipment require the use of a double
insulated mains feed.
6. Fully tighten the cable gland (if one is fitted). The
unit’s IP rating will be compromised if this is not done
correctly.
7. After making the other connections (see below), refit
the cover plate with its gasket. Take care not to damage
the gasket, and ensure that the plate is fully seated and
fixed in place with all its screws to maintain the unit’s
IP rating.
8.
Warning
– the caution label contained in
the Intellivox standard connector set must
be placed on the mains cable in close
proximity to the cable entry gland if one is fitted, or
immediately inside the connector bay if using flexible
conduit.
