32 R5 Quick installation guide
Select the power cables
Size the power cables according to local regulations to carry the nominal current given
on the type designation label of your drive.
Ensure the cooling
See table I on page 9 for the losses. The allowed operating temperature range of the
drive is -15 to +50 °C (+5 to +122 °F).No condensation or frost is allowed. For more
information on the ambient temperature and derating, see chapter Technical data in
ACS580-01 (0.75 to 250 kW, 1.0 to 350 hp) hardware manual (3AXD50000018826
[English]).
Protect the drive and input power cable
See table II on page 9 for the fuses.
If you use gG fuses, make sure that the operating time of the fuse is below 0.5
seconds. Follow the local regulations.
Install the drive on the wall
See figure R5 Figures A on page 71.
Check the insulation of the power cables and the motor
Check the insulation of the input cable according to local regulations before connecting
it to the drive.
See figure B on page 71.
1. 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 then 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, see 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.
