5 ELECTRICAL INSTALLATION / EARTHING
5.11
Regulations:
The electrical installation must be carried out in accordance with
the current national electrical regulations and installed by a qualified person.
5.12
Safety:
In the interests of electrical safety a 30 mA residual current device
(
R.C.D. not supplied
) should be installed in the supply circuit. This may be
part of a consumer unit or a separate unit.
5.13 Before starting work on the electrical supply ensure power supply is isolated.
5.14
DO NOT
allow the supply cord to contact hot surfaces, including the motor
shell, pump body or pipework. The cord should be safely routed and secured
by cable clips.
5.15
Adjacent pipes:
Adjacent suction and delivery pipes should be fitted with earthing
clamps in accordance with current regulations (Fig.7).
5.16
Earthing:
This appliance must be earthed via the terminal block under the top cover.
5.17
Pipework:
Copper or metallic pipework must have supplementary earth bonding where
the continuity has been broken by flexible hoses or plastic components.
5.18
Additional earthing:
Certain installations may require additional earthing arrangements
such as equipotential bonding. Reference should be made to the relevant regulations
concerning this subject to ensure compliance.
5.19
Connections:
The Matrix Maxi must be connected to a dedicated fused spur via a
lockable isolator to avoid unauthorized disconnection.
5.20 The electrical connection
must be
made adjacent to (not behind) the Matrix Maxi to
allow disconnection of the electrical supply should the pump module need to be
removed for service or maintenance.
