Inverter and peripheral devices Wiring
3 - 2
NOTES The life of the inverter is influenced by ambient temperature. The ambient temperature should be
as low as possible within the permissible range. Especially when mounting the inverter inside an
enclosure, take cautions of the ambient temperature. (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 damaged. 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 out-
put 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 propa-
gated interference on the input side of the inverter. Use AC or DC reactors to reduce line propa-
gated noise (harmonics). Use shielded motor power lines to reduce output noise (refer also to
section 3.9 Electromagnetic Compatibility).
Refer to the instruction manual of each option and peripheral devices for details of peripheral
devices.
