• diagnostics and panel interface board (ADPI)

• brake chopper control board (ABRC) with option +D150

Motor control

Fastening the cabinet to the floor and wall

Fasten the cabinet to the floor and wall/roof according to the panel builder’s

instructions, e.g. with outside fastening brackets or by fastening holes inside the

cabinet.

Electric welding

It is not recommended to fasten the cabinet by welding.

If the preferred fastening methods (clamping or bolting through the holes inside the

cabinet) cannot be used, proceed as follows:

• Connect the return conductor of the welding equipment to the cabinet frame at

the bottom within 0.5 metres of the welding point.

WARNING! If the welding return wire is connected improperly, the welding circuit

may damage electronic circuits in the cabinet. Ensure that the welding fumes are not

inhaled.
