WARNING

! It is the user’s responsibility to read, understand and comply with the following:

1.1.1. 

  

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 and 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  

 

together with portable products that are plugged into an electrical supply not protected by an RCCB. If in doubt consult a qualified    

 

electrician. You may obtain a Residual Current Device by contacting your Sealey stockist. You must also read and understand the    

 

following instructions concerning electrical safety.

1.1.2. 

  

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 regular intervals.

1.1.3. 

  

The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of the appliance, and  

 

the safety of the appliance operator. If in any doubt about electrical safety, contact a qualified electrician.

1.1.4. 

  

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).

1.1.5. 

  

Ensure that cables are always protected against short circuit and overload.

1.1.6. 

  

Regularly inspect power supply leads, plugs and all electrical connections for wear and damage. Inspect power connections to  

 

 

ensure that none is loose.

 

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,

 

see fuse rating at right.

 

8

  

DO NOT 

pull or carry the powered appliance by its power supply lead.

 

8

  

DO NOT 

pull power plugs from sockets by the power cable.

 

8

  

DO NOT

 use worn or damaged leads, plugs or connections. Immediately replace or have repaired by a  

 

 

 

 

qualified electrician. A U.K. 3 pin plug must be fitted according to the following instructions.

 

(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.

 

b) Connect the brown live wire to live terminal.

 

c) Connect the blue neutral wire to the neutral terminal.

 

d) After wiring, check that there are no bare wires, that all wires have been correctly connected, that the 

 

cable external insulation extends beyond the cable restraint and that the restraint is tight.

1.1.7. 

  

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 section of the cable on the cable   

 

reel is important and should be at least 1.5mm², but to be absolutely sure that the capacity of the cable is suitable for this product  

 

 

and for others that may be used in the other output sockets, we recommend the use of 2.5mm² section cable.
