32 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 IEC, UN = 400 V on page 57 (North America: table II IEC, UN = 480 V on
page 57) for the heat dissipation. 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
ACH580-01 (0.75 to 250 kW) hardware manual (3AXD50000044839 [English]).
Protect the drive and input power cable
See tables III gC (on page 58) and IV uR or aR (on page 58); (UL: table V UL on page
59) 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 67.
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 67.
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 a typical
motor must exceed 100 Mohm (reference value at 25 °C or 77 °F). For the
insulation resistance of 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.
