Installation Instructions
1. Before starting the installation, check that none of the components of the inverter are live.
2. If the inverter is installed outside the cubicle, cabinet or device space, you need to install
a separate inverter cover in accordance with protection class IP21 requirements (see
Page 3-16. There is no need to install the inverter cover if the inverter is installed in a
cubicle, separate cabinet or device space.
3. Place the motor cables sufficiently far from other cables:
– Avoid placing the motor cables in long parallel lines with other cables
– If the motor cables runs in parallel with other cables, note the minimum distances
between the motor cables and other cables given in Table 3-8.
– The given distances also apply between the motor cables and signal cables of other
systems.
– The maximum length of the motor cables is 984 feet (300m) (units with power
greater than 1.5 kW) and 328 feet (100m) (units with power from 0.75 to 1.5 kW).
– The motor cables should cross other cables at an angle of 90 degrees.
