2.1 Preparatory work
Check the unit for damage in transit or other damage.
Install and wire unit; connect all inputs and outputs required.
Proceed in the same way for the field supply unit as well.
Check whether protective measures, earthing, screening, etc. have been taken in
accordance with the system conditions involved.
Check the rated value of the supply voltage for the electronics and the fan:
•
matching transformer necessary when:
- electronics supply is not equal to 115 V/230 V
- single-phase-fan supply is not equal to 230 V
- three-phase-fan supply is not within the range of 400 V .... 690 V.
Check the rated value of the supply voltage for the armature-circuit converter's
power section; the particulars given on the rating plate must be > than the rated
line voltage.
If this condition is not satisfied, then the following applies:
- use an isolating transformer, or
- use a suitable unit.
Check the rated value of the supply voltage for the field supply unit.
(Particulars on rating plate > rated line voltage?
Is an auxiliary transformer or perhaps a series resistor necessary?)
Check the wiring, fusing, the cross-sectional areas of the cables.
Provide an option for switching binary inputs X6: 7 and X6: 8.
Check the system's EMERGENCY STOP for proper functioning! Set the system-side
monitoring functions, and activate them. Check whether auxiliaries, such as motor fans
or unit fans, function properly; while doing this, also check for correct direction of rota-
tion and voltage level as well!
