26 EN – R1…R4 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 21 (UL: table II on page 21) 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 (3AXD50000044794 [English]).
Protect the drive and input power cable
See tables III (on page 22) and IV (on page 22); (UL: table V on page 23) 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 R1…R4 Figures A on page 431.
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 B1 on page 431.
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.
