Additional information
WARNING!
Ensure that the disconnector of the supply transformer is
locked to open position, i.e. no voltage is, or cannot be connected to
drive inadvertently. Check also by measuring that there is no voltage
connected.
Basic checks with no voltage connected
If the unit is equipped with an air circuit breaker, check the current trip
limits of the breaker (preset at the factory).
General rule
Ensure the selectivity condition is fulfilled i.e. the breaker trips at a lower
current than the protection device of the supplying network, and that the
limit is high enough not to cause unnecessary trips during the
intermediate DC circuit load peak at start.
Long-term current limit
As a rule of thumb, this should be set to the rated AC current of the
module.
Peak current limit
As a rule of thumb, this should be set to a value 3-4 times the rated AC
current of the module.
Optional device. See the delivery
specific circuit diagrams.
Check the settings of the relays and breakers/switches of the auxiliary
circuits.
Optional devices. See delivery
specific circuit diagrams.
Disconnect any unfinished or unchecked 230/115 VAC cables that lead
from the terminal blocks to the outside of the equipment.
Locate the PPCS branching unit (APBU-xx). Enable memory backup
battery by setting actuator 6 of switch S3 to ON.
By default, memory backup is
switched off to save the battery.
Connecting voltage to input terminals and auxiliary circuit
WARNING!
When voltage is connected to the input terminals, voltage
may also be connected to the auxiliary circuits of the drive.
Make sure that it is safe to apply voltage. Ensure that:
• nobody is working on the unit or circuits that are wired from outside into
the cabinets
• cabinet doors are closed
• covers of motor terminal boxes are in place.
Open the earthing/grounding switch (if present).
The earthing/grounding switch and
the main disconnecting device are
either mechanically or electrically
interlocked so that the earthing/
grounding switch can only be closed
when the main disconnecting switch
is open, and vice versa.
Close the supply (rectifier) unit switch-disconnector.
On units with line contactors, the
supply unit charges the contactor
control capacitors (3 s at first start).
The supply unit performs a fault
status check.
Close the main breaker of the supply transformer.
Close the auxiliary circuit On/Off switch.
