:
BEFORE USING THIS PRODUCT, PLEASE READ THE INSTRUCTIONS CAREFULLY. MAKE CAREFUL NOTE OF SAFETY INSTRUCTIONS,
WARNINGS AND CAUTIONS. THIS PRODUCT SHOULD ONLY BE USED FOR ITS INTENDED PURPOSE. FAILURE TO DO SO MAY CAUSE DAMAGE

1. SAFETY INSTRUCTIONS
1.1. ELECTRICAL SAFETY
WARNING!
It is the responsibility of the owner and the operator to read, understand and comply with the following:
You must check all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and any
other connectors for wear or damage. You must ensure that the risk of electric shock is minimised by the installation of appropriate safety
devices. A Residual Current Circuit Breaker (RCCB) should be incorporated in the main distribution board. We also recommend that a
Residual Current device (RCd) is used. It is particularly important to use an RCd with portable products that are plugged into a supply
which is not protected by an RCCB. If in any doubt consult a qualified 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 that all portable electrical appliances, if used on business premises, are 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 the appliance operators. If in any doubt about electrical safety, contact a qualified electrician.
1.1.3. ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply. See 1.1.1. and 1.1.2.
and use a Portable Appliance Tester.
1.1.4. ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply cables and plugs for wear or damage and check all connections to
ensure that none are loose.
1.1.6.
Important:
ensure that the voltage marked on the appliance matches the power supply to be used
and that the plug is fitted with the correct fuse.
1.1.7.
DO NOT
pull or carry the appliance by the power cable.
1.1.8.
DO NOT
pull the plug from the socket by the cable.
1.1.9.
DO NOT
use worn or damaged cables, plugs or connectors. Immediately have any faulty item
repaired or replaced by a qualified electrician. When a BS 1363/A UK 3 pin plug is damaged, cut
the cable just above the plug and dispose of the plug safely.
Fit a new plug according to the following instructions (UK only).
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’.
d) After wiring, check that there are no bare wires, that all wires have been correctly connected, that the cable outer insulation
extends beyond the cable restraint and that the restraint is tight.
double insulated products, which are always marked with this symbol , are fitted with live (brown) and neutral (blue) wires only.
To rewire, connect the wires as indicated above -
DO NOT
connect either wire to the earth terminal.
1.1.10. Products which require more than 13 amps are supplied without a plug. In this case you must contact a qualified electrician to ensure
that a suitably rated supply is available. We recommend that you discuss the installation of an industrial round pin plug and socket with
your electrician.
1.1.11. If an extension reel is used it should be fully unwound before connection. A reel with an RCd fitted is preferred since any appliance
plugged into it will be protected. The cable core section is important and should be at least 1.5mm², but to be absolutely sure that the
capacity of the reel is suitable for this product and for others which may be used in the other output sockets, we recommend the use of
2.5mm² section cable.
WARNING!
Be very cautious if using a diesel generator. The generator must be stable with regard to frequency (H3), voltage
and wave form. The output must be higher than the power (kVA) of the inverter. The diesel generator must also be self
regulating. If any A.M. feature is not respected the working of the regulation card may be affected.
Use of a generator without a regulator may be dangerous and will invalidate your inverter warranty.

1.2. GENERAL SAFETY
DANGER! Unplug the inverter from the mains power supply before connecting or disconnect cables or performing maintenance or
service. Direct contact with the inverter circuit is dangerous.
Keep the inverter and cables in good working order and condition.
Take immediate action to repair or replace damaged parts.
Use genuine parts and accessories only.
Unapproved parts may be dangerous and will invalidate the warranty.
Keep the inverter clean for best and safest performance.
locate the inverter in a suitable work area. ensure that the area has adequate ventilation as welding fumes are harmful.
WARNING! Cable connectors must be turned fully into the quick plugs to ensure a good electrical contact. Loose connections will
cause overheating, rapid deterioration and loss in efficiency.
ensure that there is no obstruction to the flow of clean, cool air and ensure that there are no conductive dusts, corrosive vapours or humidity
which could enter the inverter and cause serious damage.
Keep the work area clean and tidy and free from unrelated materials. Also ensure that the work area has adequate lighting.
WARNING: Use welding head shield to protect eyes and avoid exposing skin to ultraviolet rays given off by electric arc. Wear safety
welding gauntlets.
Remove ill fitting clothing, remove ties, watches, rings and other loose jewellery and contain long hair.
ensure that the workpiece is correctly secured before operating the inverter.
Avoid unintentional contact with workpiece. Accidental or uncontrolled arcing on the electrode holder may be dangerous.
Protect cables from heat and sharp or abrasive items.
Keep unauthorised persons away from the work area. Any persons working within the area must adorn the same protective items.
Stand correctly keeping a good footing and balance, ensure that the floor is not slippery and wear non-slip shoes.
