1. SAFETY INSTRUCTIONS
1.1. ELECTRICAL SAFETY. p WARNING! It is the users responsibility to read, understand and comply with the following:
You must check all electrical equipment and appliances to ensure they are safe before using. You must inspect power supply leads, plugs and
all electrical connections for wear or damage. You must ensure the risk of electric shock is minimised by the installation of appropriate safety
devices. An RCCB (Residual Current Circuit Breaker) should be incorporated in the main distribution board. We also recommend that an RCD
(Residual Current Device) is used with all electrical products. It is particularly important to use an RCD with portable products that are plugged
into an electrical supply not protected by an RCCB. If in doubt consult a professional electrician. You may obtain a Residual Current Device by
contacting your Sealey dealer. You must also read and understand the following instructions concerning electrical safety.
1.1.1. The Electricity At Work Act 1989 requires all portable electrical appliances, if used on business premises, to be tested by
a qualified electrician, using a Portable Appliance Tester (PAT), at least once a year.
1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances,
and the safety of appliance operators. If in any doubt about electrical safety, contact a qualified electrician.
1.1.3. Ensure the insulation on all cables and the product itself is safe before connecting to the mains power supply.
See 1.1.1. & 1.1.2. above and use a Portable Appliance Tester (PAT).
1.1.4. Ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply leads and plugs for wear or damage and connections to ensure that none are loose.
1.1.6. Important: Ensure the voltage marked on the product is the same as the electrical power supply
to be used, and check that plugs are fitted with the correct capacity fuse. A 13 amp plug may require
a fuse smaller than 13 amps for certain products (subject to 1.1.10. below).
1.1.7. DO NOT pull or carry the powered appliance by its power supply lead. Products such as
welders must not be pulled or carried by their output cables.
1.1.8. DO NOT pull power plugs from sockets by the power cable.
1.1.9. DO NOT use worn or damage leads, plugs or connections. Immediately replace or have repaired by
a qualified electrician. Where a U.K. 3 pin plug with ASTA/BS approval is fitted, in case of damage, cut off
and fit a new plug according to the following instructions (discard old plug safely).
(UK only - see diagram at right). Ensure the unit is correctly earthed via a three-pin plug.
a) Connect the GREEN/YELLOW earth wire to the earth terminal E.
b) Connect the BROWN live wire to the live terminal L.
c) Connect the BLUE neutral wire to the neutral terminal N.
After wiring, check there are no bare wires, that all wires have been correctly connected, that the cable outer insulation
extends past the cable restraint and that the cable restraint is tight.
Double insulated products are often fitted with live (BROWN) and neutral (BLUE) wires only. Double insulated products are always marked with
this symbol . To re-wire, connect the brown & blue wires as indicated above. DO NOT connect the brown or blue wires to the earth terminal.
1.1.10. Cable extension reels. When a cable extension reel is used it should be fully unwound before connection. A cable reel with an RCD
fitted is recommended since any product which is plugged into the cable reel will be protected. The cross section of the cores in the cable
is important and should be at least 1.5mm2, but to be absolutely sure that the capacity of the cable reel is suitable for this product and
for others that may be used in the other output sockets, the use of 2.5mm2section is recommended .
