Control circuit specifications
2.3.4
Wiring instructions
1)
Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and
power circuits (including the 200V relay sequence circuit).
2)
Use two or more parallel micro-signal contacts or twin contacts to
prevent a contact faults when using contact inputs since the
control circuit input signals are micro-currents.
3)
Do not apply a voltage to the contact input terminals (e.g. STF) of the control circuit.
4)
Always apply a voltage to the fault output terminals (A, B, C) via a relay coil, lamp, etc.
5)
It is recommended to use the cables of 0.75mm
2
gauge for connection to the control circuit terminals.
If the cable gauge used is 1.25mm
2
or more, the front cover may be lifted when there are many cables running or
the cables are run improperly, resulting in an operation panel contact fault.
6)
The wiring length should be 30m(200m for terminal FM) maximum.
2.3.5
When connecting the operation panel using a connection cable
When connecting the operation panel (FR-DU07) to the inverter using a cable, the operation panel can be mounted
on the enclosure surface and operationality improves.
CAUTION
Do not connect the PU connector to the computer's LAN port, FAX modem socket or telephone connector.
The inverter and machine could be damaged due to differences in electrical specifications.
REMARKS
