CAUTION: ISOLATE THE 230v ELECTRICITY SUPPLY
▶ Ensure that the electricity supply is safely Isolated
and secured to prevent inadvertent re-connection.
Information on safe isolation can be found in the
Health and Safety Executive guidance HSG85. Using
test equipment approved to GS38 confirm that the
electricity supply is disconnected.
▶ The mains electrical supply to the boiler and system
wiring centre must be common and through either a
common fused double pole isolator or a fused three
pin plug and unswitched socket.
▶ The isolator shall be sited next to the boiler for new
systems and where practicable, replacement boilers.
▶ The isolator must have a contact separation of 3mm
minimum between all poles.
▶ Any additional components that are connected to the
boiler with mains electrical supply must not have a
separate supply.
▶ External 5 Amps.
▶ When stripping wires ensure copper strands do not
fall into the control box.
Route the power cable down the side panel using the clip
on the support panel to the external connection point
avoiding any potentially hot surfaces allowing sufficient
cable to pivot the control box into the service position.
NOTICE: External devices
▶ The boiler and any external devices connected to the
boiler must have a single point of isolation.
See the following pages of electrical diagrams for
details of different systems.
