3. Planning, commissioning and maintenance
3.1 Commissioning steps
3.1.1 Step 1: Wiring
Wiring with switch apparatus (3.2.1)
Hard-wire with switch apparatus and other components acc. to the application requirements.
Wiring examples see chapter 7.
Connection of contactors (3.2.2)
Use spark suppression, for larger contactors also interface relays to keep good lifetime of the
UMC22 internal relays.
Motor current = Set current versus wiring (3.2.3)
Have a look at the wiring of the motor to fi x the correct Set current for perfect motor protection.
Example:
For 冑3 (inner delta) wiring the parameter Current factor can be changed to 1.73 to get displayed the
real Set currents on the Control Panel and in the control system.
External current transformer for higher currents (3.2.4)
Connect external current transformers for higher currents. Current factor see above.
3.1.2 Step 2: Interfacing to the fi eldbus
Addressing (3.3.1)
The UMC22 is provied with a fi eldbus neutral interface. Use an appropriate FieldBusPlug to connect
it to the fi eldbus.
The slave address can be adjusted by
- using the Control Panel or
- using the Addressing-Set CAS21-FBP.
The bus master is normally defi ned by the control system.
