Inverter and peripheral devices Wiring
3 - 2
NOTES The life of the inverter is influenced by surrounding air temperature. The surrounding air
temperature should be as low as possible within the permissible range. This must be noted
especially when the inverter is installed in an enclosure (refer to section 2.4.2).
Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully
away from the main circuit to protect them from noise (refer to section 3.2).
Do not install a power factor correction capacitor or surge suppressor on the inverter output
side. This will cause the inverter to trip or the capacitor and surge suppressor to be dam-
aged. If any of the above devices are connected, immediately remove them.
Electromagnetic Compatibility
Operation of the frequency inverter can cause electromagnetic interference in the input and
output that can be propagated by cable (via the power input lines), by wireless radiation to
nearby equipment (e.g. AM radios) or via data and signal lines.
Activate the integrated EMC filter (and an additional optional filter if present) to reduce air
propagated interference on the input side of the inverter. Use AC or DC reactors to reduce
line propagated noise (harmonics). Use shielded motor power lines to reduce output noise
(refer also to section 3.7 Electromagnetic Compatibility).
Refer to the instruction manual of each option and peripheral devices for details of periph-
eral devices.
