Required tools
To do the electrical installation, you need these tools:
• wire stripper
• screwdriver set (Torx, flat and/or Phillips, as appropriate)
• torque wrench.
Grounding the motor cable shield at the motor end
For minimum radio-frequency interference, ground the cable shield 360 degrees at the
cable entry of the motor terminal box.
Measuring the insulation
Measuring the insulation is typically not required in North American installations.
■ Measuring the insulation resistance of the drive
WARNING!
Do not do any voltage withstand 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.
■ Measuring the insulation resistance of the input power cable
Before you connect the input power cable to the drive, measure its insulation resistance
according to local regulations.
■ Measuring the insulation resistance of the motor and motor cable
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or death,
or damage to the equipment can occur. If you are not a qualified electrical
professional, do not do installation, commissioning or maintenance work.
