This guide instructs briefly how to install the drive. For more detailed instructions, engineering guide lines, technical data and

complete safety instructions, see the hardware manual.

Follow the safety listed instructions in Chapter 1.

WARNING:

Select the power cables according to local regulations to carry the nominal current given on the type designation label of

your drive.

See Table 3-3 for the losses and the cooling air flow through the drive. The allowed operating temperature range of the drive

without derating is -5°F to +104°F.

See Table 5-2. Check that the operating time of the fuse is below 0.5 seconds.

Check the insulation of the input cable according to local regulations before connecting it to the drive. Check the insulation

of the motor cable and motor when the cable is disconnected from the drive. Measure the insulation resistance between

each phase conductor and the Protective Earth conductor using a measuring voltage of 1000VDC. 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

moisture is suspected, dry the motor and repeat the measurement.
