5.3. Control connections
5.3.1. Connection procedure
•
remove the front panel that is secured with screws.
•
for control connections use cable of 0,5 mm
2
screened
•
connection cable should enter at bottom.
•
connect screen to earth at the drive only .
•
connect control cable to terminals
(connections are shown in FIG 2).
•
refit the front panel
NOTE : always segregate control and power cabling !

6. Drive status indication
6.1. On the front panel of the drive
•
LED "POWER" (red) : input voltage is present, all internal voltage levels are correct
•
LED "FAILURE" (red) : internal or external trip (e.g. overvoltage, overcurrent, short-circuit ...)
the drive is stopped (disconnected from the load)
6.2. Remote indication
•
Volt-free change-over relay contact
Control terminals :
5
- normally open
6
- common
7
- normally closed
Relay energised when : drive healthy
Relay de - energised when : power off or drive tripped (disconnected from the load)
