must be adhered near the drive and clearly visible.
6. Measure the insulation resistance
Drive:
Do not do voltage tolerance or insulation resistance tests on the drive as testing can
damage the drive.
Input power cable:
Before you connect the input power cable to the drive, measure its
insulation resistance according to local regulations.
Motor and motor cable:
1.
Make sure that the motor cable is connected to the motor and disconnected from the
drive output terminals T1/U, T2/V and T3/W.
2.
Use a voltage of 1000 V DC to measure the
insulation resistance between each phase
conductor and the protective earth conductor. The
insulation resistance of an ABB motor must be
more than 100 Mohm (at 25 °C [77 °F]). For the
insulation resistance of other motors, refer to the
manufacturer’s instructions.
Note:
Moisture inside the motor reduces the
insulation resistance. If you think that there is
moisture in the motor, dry the motor and do the
measurement again.
7. Make sure that the drive is compatible with the
grounding system
You can install all drive types to a symmetrically grounded TN-S system (center-grounded
wye). The drive is delivered with the EMC and VAR screws installed. The material of the screws
(plastic or metal) depends on the product variant. The table shows when to remove the metal
EMC screw (disconnect the internal EMC filter) or metal VAR screw (disconnect the varistor
circuit).
8. Connect the power cables
Connection diagram (shielded cables)
1.
Disconnecting device.
2.
Two protective earth (ground) conductors. Drive safety standard IEC/EN61800-5-1
requires two PE conductors, if the cross-sectional area of the PE conductor is less than
10 mm
2
Cu or 16 mm
2
Al. For example, you can use the cable shield in addition to the
fourth conductor.
3.
Use a separate grounding cable or a cable with a separate PE conductor for the line side,
if the conductivity of the fourth conductor or shield does not meet the requirements for
the PE conductor.
4.
Use a separate grounding cable if the conductivity of the shield is not sufficient, or if
there is no symmetrically constructed PE conductor in the cable.
5.
360° grounding of the cable shield is required for the motor cable and brake resistor
cable (if used). It is also recommended for the input power cable.
6.
Brake resistor and resistor cable (optional, for frames R2...R4 only).
Connection procedure
(shielded cables)
For the tightening torques, refer to
Terminal data for the power cables
.
