2.5.5.3 Wiring to Control Terminals
Control terminal connectors can be unplugged from the
adjustable frequency drive for ease of installation, as
shown in Figure 2.18.
1. Open the contact by inserting a small screwdriver
into the slot above or below the contact, as
shown in Figure 2.20.
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 12 Terminal and Applicable Wire for control terminal
wiring sizes.

2.5.5.4 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, electrical noise may occur
that will disturb the entire system. Solve this problem by
fitting an equalizing cable next to the control cable.
Minimum cable cross-section: 0.025 in

(16 mm

).
