Electrical Supply
The product MUST be earthed.
All system components shall be of an approved type and all
wiring to current I.E.E. wiring regulations.
External wiring must be correctly earthed, polarised and in
accordance with the relevant standards.
In GB, this is BS 7671.
In IE, this is the current edition of ETCI rules.
The product MUST be connected to a permanent 230V ac,
50Hz supply.
Connection of the whole electrical system of the product,
including any heating controls, to the electrical supply MUST
be through one common isolator and must be fused 3 Amp
maximum.
Isolation should be by a double pole switched fused spur box,
with a minimum gap of 3mm for both poles. The fused spur
box should be readily accessible and preferably adjacent to
the product. It should be identified as to its use.
Alternatively connection can be made through an unswitched
shuttered socket and 3A fused 3-pin plug both to the current
issue of BS 1363, provided they are not used in a room
containing a bath or shower.
Wiring to the product must be PVC 85°C insulated cable, not
less than 0.75mm2 (24/0.20mm).
IMPORTANT: Risk of fatal electric shock from touching live
connections.
Before working on the system wiring, including the Fluropro,
isolate the power supply.
The circuit board can be damaged if short circuited through
the connection leads. For safety purposes, a max. of 30 mm
of insulation may be removed from the ends of 230 V leads
which will be connected to Fluropro wiring connectors. If more
insulation is removed, there is a risk of short circuiting the
circuit board.
When exchanging the solar controller in an existing
system, sensor-curve characteristics should be taken
into consideration and the sensors should be replaced if
necessary!
The immersion heater must be installed with an additional
relay or contactor with a circuit-breaking capacity of at least
16 A. Never operate an immersion heater in connection with
the Fluropro without an additional external relay or contactor.
