4 Electrical connection
!
This appliance must be earthed.
Supply 230V 50Hz single phase.
Current rating 0.55 amp max (inductive).
Fuse: external 3 amp.
All electrical work should be carried out to
I.E.E. standards by a competent electrician.
The electrical connection to the heater is
made by means of a three pin plug-in
power connector. Live, neutral and earth
connections should be made via a flexible
supply cable to the power connector and
routed clear of the heater or tubes. The
flexible supply cables should be of 0.5mm
complying with BS 6500:1990.
Note SL heaters require an electrical cable
between the burner unit and the fan
assembly. This to be provided by the
installing/electrical contractor.
!
Wiring
The wires in the mains lead are coloured in
accordance with the following code:
Green & yellow
Earth
Blue
Neutral
Brown
Live
Instructions for connecting mains
lead to plug
Connect green and yellow to plug terminal
marked E. Connect blue wire to terminal
marked N. Connect brown wire to terminal
marked L.
It is recommended that the electrical circuit
controlling the heater or group of heaters
incorporates thermostats, a time switch and if
required, manual control switches and a frost
thermostat.

Circuits and controls
All such controls and switchgear must be
rated to handle the total inductive load of
the circuit they control. Load per Ambi-Rad
heater is 0.55 amp. For large installations,
the use of relays and contactors should
be considered. The method of connection
to the electrical supply must facilitate
complete isolation and should be made
via a fused double pole isolator having a
contact separation of at least 3mm in all

Alternatively, connection may be made
via a fused three pin plug and unswitched
shuttered socket, both complying with
the requirements of BS 1361:1971 (1986).
Ensure that a copy of the lighting
instructions plate is affixed adjacent to
the electricity supply switch. Should this
switch serve more than one heater it is only
necessary to affix one copy per service
switch.
