Installation instructions 75
Checking the insulation of the assembly
Drive
Do not make any voltage tolerance or insulation resistance tests on any part of the drive as
testing can damage the drive. Every drive has been tested for insulation between the main
circuit and the chassis at the factory. Also, there are voltage-limiting circuits inside the
drive which cut down the testing voltage automatically.
Input cable
Check the insulation of the input cable according to local regulations before connecting it
to the drive.
Motor and motor cable
Check the insulation of the motor and motor cable as follows:
1. Check that the motor cable is disconnected from the drive output terminals T1/U2,
T2/V2 and T3/W2.
2. Measure the insulation resistance between each phase conductor and the Protective
Earth conductor using a measuring voltage of 1000 V DC. The insulation resistance of
an ABB motor must exceed 100 Mohm (reference value at 25 °C or 77 °F). For the
insulation resistance of other motors, consult the manufacturer’s instructions. Note:
Moisture inside the motor casing will reduce the insulation resistance. If you suspect
moisture, dry the motor and repeat the measurement.
Installation alternatives
For an installation example of how to install the standard drive module into a Rittal cabinet,
see chapter Installation example of drive module with IP20 shrouds (option +B051). You
can install the drive module into a cabinet using different procedures depending on the
drive configuration. Obey the general power and control cable installation instructions that
we give in this chapter and see the installation example of your drive configuration in the
following chapters.
Standard drive module configuration and option +B051
For an installation example on how to install the drive module into a Rittal TS 8 cabinet,
see chapter Installation example of drive module with IP20 shrouds (option +B051) on
page 91. See also ACS530-04 drive modules (200 to 560 kW, 300 to 700 hp) quick
installation guide (3AXD50000015469 [English]).
Optional input power cable connection terminals and
ground busbar assembly (+H370)
Connect the input power cable connection terminals as shown in chapter Step-by-step
drawings for an installation example of drive module with options +B051 and +E208 in
Rittal TS 8 600 mm wide cabinet on page 175.
