Securing the Fitting and the Joint

Use positioner clamps or a vice to secure the fitting and the
joint to be made before welding. The fitting manufacturer's
installation instructions, local and national regulations have
to be respected in all cases.
A welding process must never be repeated with the same
fitting, since this may cause parts under power to be acces-
sible to the touch.

the following conductor sections:
up to 20 m: 1.5 mm² (2.5 mm² recommended);
over 20 m: 2.5 mm² (4.0 mm² recommended);
When using the extension cable, it has always to be

Checking the Product for Damage

Before every use of the product, check safety features and
possibly existing parts with minor damage for proper func-
tion. Make sure that the push-on connection terminals work
properly, that contact is fully established, and that the con-
tact surfaces are clean. All parts have to be installed correct-
ly and properly conform to all conditions in order for the
product to function as intended. Damaged safety features
or functional parts should be properly repaired or replaced
by an approved service shop.

away.
