Forming circuit
The S120 Combi Power Module has internal PTC resistors to pre-charge the DC link
capacitors. The resistors can be used to form the DC link capacitors of the S120 Combi
Module as well as the expansion axes (Motors Modules Booksize Compact).
During the forming process, it is not permissible for the S120 Combi Power Module to
receive a switch-on command. Therefore, disconnect the 24 V power supply to the S120
Combi Power Module.
Procedure
S120 Combi Power Modules
1. Connect the S120 Combi Power Module with line reactor to the line supply (see the
connection example in Chapter "S120 Combi Power Modules / interface description").
2. Keep the module connected to the line supply for approx. 1 hour without issuing a switch-
on command.
Expansion axis (Motor Module Booksize Compact)
1. Connect the expansion axis to be formed to the DC link of the S120 Combi Power
Module.
2. Connect the S120 Combi Power Module with line reactor to the line supply (see the
connection example in Chapter "S120 Combi Power Modules / interface description").
3. Keep the S120 Combi Power Module and the expansion axis connected to the line supply
for approx. 1 hour without issuing a switch-on command.
DANGER
Risk of electric shock
As a result of the DC link capacitors, a hazardous voltage is present for up to 5 minutes
after the power supply has been switched off. Work may only be carried out on the
components after this time has elapsed.
14.6 Recycling and disposal
The applicable national guidelines must be observed when disposing of the product.
The products described in this Equipment Manual are extensively recyclable on account of
the low-toxic composition of the materials used. For environmentally-compliant recycling and
disposal of your electronic waste, please contact a company for the disposal of electronic
waste.
