4.2. Field wiring and earth grounding
01.
Inverter terminal motor connection wire (U,V,W terminal output wire)and
inverter terminal power connection wire (R,S,T terminal input wire)should
keep distance enough as possible as can.
02.
U,V,W terminal 3 motor wires should be placed in metal tube or metal
wiring tank as possible as.
03.
Generally control signal wire should use shield cable, when shield layer
connect to inverter
which closed to inverter side.
04.
Inverter
floor, it cannot connect to earth grounding through other device, and the
location of earth grounding should close to inverter as possible as.
05.
Strong current cable (R,S,T,U,V,W) cannot parallel wiring closely with
control signal wire, and bundled together is prohibited. It should keep distance
from over 20~60 cm (relative to strong current size). When it's necessary to
intersect, it should be orthogonal crossing, show as Fig.4-2.
06.
Earth grounding wire for strong current should separately connect to
earth grounding with control signal and sensor earth grounding wire for weak
current.
07.
Forbid to connect inverter input terminal(R, S, T) to other devices.
150
terminal, it should be the single end earth grounding
terminal erath grounding cable must directly connect to
Power wire or motor cable
Control signal wire
