2.4.5.3 Wiring to Control Terminals
Control terminal connectors can be unplugged from the
Adjustable frequency drive for ease of installation, as
shown in
Figure 2.11 .
1. Open the contact by inserting a small screwdriver
into the slot above or below the contact, as
shown in
Figure 2.13 .
2. Insert the bared control wire into the contact.
3. Remove the screwdriver to fasten the control wire
into the contact.
4. Ensure the contact is firmly established and not
loose. Loose control wiring can be the source of
equipment faults or less than optimal operation.
See 10.1 Power-dependent Specifications for control terminal
wiring sizes.
See 6 Application Set-Up Examples for typical control wiring
connections.

2.4.5.4 Using Shielded Control Cables
Correct shielding
The preferred method in most cases is to secure control
and serial communication cables with shielding clamps
provided at both ends to ensure best possible high
frequency cable contact.
If the ground potential between the adjustable frequency
drive and the PLC is different, electric noise may occur that
will disturb the entire system. Solve this problem by fitting
