2.6 Electrical Installation
All electrical wiring and connections must be
in accordance with the relevant European,
National, and Local regulations as well as to
IEE Standards.
Ensure that the Electric and Gas supplies
are turned off before any electrical work is
carried out on the heater.
Also ensure that wiring cannot make contact
with any metal surfaces liable to be subject
to high temperatures, and where insulation
of the wiring could be impaired as a result of
such contact.
All LCSBD models must be earthed.
Warning
Ensure that the electrical supply is
compatible to the heater
.
ALL HEATERS ARE NEUTRALLY RESET
Caution
The main electrical supply must not be
switched off or disconnected as a method
for stopping the heater, the exception to this
is in the event of an emergency, or when the
heater has been allowed to cool sufficiently
to prevent any damage from being
sustained to the heater or its controls (ie:
during servicing).
Claims for damage will not be considered if
they have resulted from incorrect wiring or
the incorrect use of the heater.
Each heater requires a permanent 230V
50Hz 1ph electrical supply, which must be
wired through a fused isolator fitted with a
fuse of the correct rating (see section 7.1).
The correct supply connection points for the
live, neutral, and earth.
Wiring diagrams are also detailed within this
manual, (section 6.0)
The electrical supply isolator should be
mounted adjacent to the air heater in an
easily accessible position to allow for
servicing isolation, or emergency shut off.
Electrical panel
Warning
Ensure that the mains isolator is turned
OFF
before undertaking any electrical work on
the heater.
Access to the electrical panel is
gained by opening the right hand heater
side panel.
Warning
Ensure that all connections are secure and
that there are no loose strands which could
bridge across the terminals.
A minimum conductor size of 1.0 mm
(diameter) is required.
Caution
When using Optimised Controller
Consideration should be made when routing
the cable between the control and heater.
Avoiding where possible any existing
cables and switch gear as any induced
voltage may affect the operation of the
sequential control box within the heater.
It is recommended that screened cable
is used when the control is to be sited
more than 10 metres away from the
heater
One electrical panel per heater is required,
unless heaters are specified for multiple
heater control applications. On no account
should more than one heater be connected
to a single time switch or thermostat.
The only exception to this is when a control
panel suitable for multiple
heater
applications is supplied by the manufacturer.
Any ancillary electrical items e.g. room
thermostats , time switches, remote panels
etc, must be wired into the heater electrical
circuit in accordance with the diagrams
provided.
Note
When external controls operate to switch the
heater
OFF
, power to the heater should
remain to allow the fan to continue to
operate to sufficiently cool the heater
thereby preventing damage to the heat
exchanger.
