Chapter 4 Wiring
(9)The overall wiring length should be 100 m maximum.
Especially for long distance wiring, the fast-response current limit
function may be reduced or the equipment connected to the inverter
output side may malfunction or become faulty under the influence of
a charging current due to the stray capacity of the wiring. therefore,
note the overall wiring length.
(10) Do not install a power factor correction capacitor, surge
suppressor or radio noise filter on the inverter output side.
(11) Before starting wiring or other work after the inverter is operated,
wait for at least 10 minutes after the power supply has been switched
off, and check that there are no residual voltage using a tester or the
like. The capacitor is charged with high voltage for some time after
power off and it is dangerous.
(12) Electromagnetic wave interference
The input/output (main circuit) of inverter includes high frequency
components, which may interfere with the communication devices
(such as AM radios) used near the inverter. In this case,set the EMC
filter valid to minimize interference.
(13) Across P/+ and PR terminals, connect only an external
regenerative brake discharge resistor. Do not connect a mechanical
brake.
