2. BEFORE YOU START USING THE UNIT
2.1. UNPACkING
The equipment is packed in durable packages, designed specially for it. Nevertheless, before using
the equipment, always make sure it was not damaged during transport. Also check that you have
received what you ordered and that there are instructions for it. NOTE! The packaging material of
the products is suitable for recycling.
2.2. PLACEMENT OF THE UNIT
Place the unit on a horizontal, solid, and clean surface. Shield it from heavy rain and scorching
sun. Make sure that cooling air circulates freely.
2.3. SERIAL NUMBER
The serial number of the unit is marked on the rating plate of the unit. The serial number makes
it possible to trace product manufacturing series. You might need the serial number when placing
spare parts orders or when planning maintenance.
2.4. CONNECTION TO THE MAINS SUPPLY
The Kempact 2520 is delivered equipped with a five metre mains cable without a plug. Installation
of the plug should be carried out only by a competent electrician. For fuse and cable sizes, see the
technical data in the end of this document.
2.5. GROUND CABLE
Fasten the earth clamp of the return current cable carefully, preferably direct onto the piece to be
welded. The contact surface of the earth clamp should always be as large as possible. Clean the
fastening surface from paint and rust. Use at least 35 mm² cables. Thinner cross-sectional areas
cause overheating of connectors.
