IT (ungrounded) systems
A drive equipped with no EMC filter or with EMC E210 is suitable for IT
(ungrounded systems). If the drive is equipped with EMC E202, disconnect
the filter before connecting the drive to an ungrounded system. For detailed
instructions on how to do this, please contact your local ABB representative.
WARNING!
If a drive with EMC E202 is installed on an IT system [an
ungrounded power system or a high resistance-grounded (over 30 ohms) power
system], the system will be connected to earth potential through the EMC filter
capacitors of the drive. This may cause danger or damage the unit.
Required tools
• set of screw drivers
• torque wrench with 500 mm (20 in.) or 2 x 250 mm (2 x 10 in.) extension bar
• 19 mm (3/4 in.) socket
for frame size R7: 13 mm (1/2 in.) magnetic end socket
for frame size R8: 17 mm (11/16 in.) magnetic end socket.
Checking the insulation of the assembly
Every drive has been tested for insulation between the main circuit and the chassis
(2500 V rms 50 Hz for 1 second) at the factory. Therefore, do not make any voltage
tolerance or insulation resistance tests (e.g. hi-pot or megger) on any part of the
drive. Check the insulation of the assembly as follows.
WARNING!
Check the insulation before connecting the drive to the mains. Make
sure that the drive is disconnected from the mains (input power).
1. Check that the motor cable is disconnected from the drive output terminals U2,
V2 and W2.
2. Measure the insulation resistances of the motor cable and the motor between
each phase and the Protective Earth by using a measuring voltage of 1 kV DC.
The insulation resistance must be higher than 1 Mohm.
