Chapter 3 Ambient Environment and Installation<br />
Make external connections according to the following instruction. Check connections after<br />
wiring to make sure all connections are correct. (Do not use the control circuit buzzer to check<br />

The inverter uses dedicated power line A general noise filter may not provide<br />
rightful results<br />
Add a noise filter or separation transformer whenter<br />
shares the power line with other machines.<br />
the inverter shares the power line with other machines.<br />
(A) Main circuit’s wiring must separate from other high voltage or high current power line to<br />
avoid noise interference. Refer to the figures below:<br />
A noise filter in the output of the main circuit can suppress conductive noise. To prevent radiative noise,<br />
the wires should be put in a metal pipe and distance from signal lines of other control machines for more<br />
than 30 cm.<br />
