CAUTION

Connecting lines and signal lines must be laid so as to avoid nega-

tive effects on the function of the units through capacitive or induc-

tive interference!

Interference is frequently coupled and de-coupled in long cables.

Therefore, medium-frequency inverter cables and control cables

must be routed separately. The influence of interfering cables on

cables susceptible to interference can be minimized by keeping the

following distances:

D > 100 mm if cables are run in parallel for < 10 m,

D > 250 mm if cables are run in parallel for > 10 m.

MF inverters should be mounted close to the welding systems so as

to avoid cable lengths of more than 25 m.

CAUTION

Connection cables may come off and apply dangerous voltage to

system components!

It is crucial that cables are properly fixed.

L PE connection : Connect to a central earth point. Make sure that cable

cross-sectional areas are sufficiently large!

L All conductor cross-sections must be large enough for for the loads to be

connected.

L U1 connection : Connect to L1 system phase.

L V1 connection : Connect to L2 system phase.

L W1 connection : Connect to L3 system phase.

L U2 and V2 welding transformer outputs : Connect to PSG 3000 (U, V)

welding transformer.
