This document applies to following Moeller Electric Motor Starters:
Where (*,*) refers to the available coil voltage; either (230V 50Hz, 240V 60Hz) or (400V 50Hz, 440V 60Hz)
This product should be installed, commissioned and maintained by a competent person in accordance with these instructions, and the
appropriate clauses of the current edition of the IEE Wiring Regulations (BS 7671).
It is essential that the mains electricity supply that will be, or is currently, connected to this product is isolated before commencing work.
All connections should be made to the product as instructed; field cables should not be stressed, and terminal screws should be fully
tightened to the recommended torque values.
To avoid risk of fire, do not exceed the maximum rated current of this product.
Please ensure that these instructions are left with the person responsible for the future operation and maintenance of this product.
Motor Starters supplied in insulated enclosures are “Totally Insulated” in accordance with BS EN 60439-1:1999.
The insulating material that therefore encapsulates all the electrical apparatus must not be pierced by conducting parts such as metal
screws, conduit, cable glands, etc. (See BS7671. IEE Regs. 413-03)
The metal mounting plate and other exposed conductive parts within the enclosure are therefore not earthed.
For conduit entry, insulated conduit fittings must be used for attaching plastic or metal conduit to the enclosure, thus avoiding metallic
penetration of the enclosure wall.
Where cable entry to the Motor Starter is required to be via metal trunking, this shall be done by insulated conduit fittings. Alternatively,
where the enclosure is to be butted up to the trunking, an opening should be cut into the wall of the trunking to clear the insulated
grommets or glands that must be fitted to the enclosure openings (knockouts). The enclosure must not be attached to the trunking itself
unless screws of insulating materials are used.
Motor Starters supplied in insulated enclosures with transparent polycarbonate lids are recommended to be occasionally cleaned with
an anti-static cleaning cream/polish; on no account should these covers be cleaned with any chemical solvent, such as trichlorethylene,
acetone, varnish thinner or liquid fuel.
These products are supplied without an Overload Relay.
An Overload Relay must be fitted and wired to the Contactor Q11 and the flying leads terminated, as
indicated elsewhere in this document, before the starter is put into service.
DANGER OF DEATH exists if this instruction is not followed.
