4.8.2 Wiring to Control Terminals
Control terminal connectors can be unplugged from the adjustable frequency
drive for ease of installation, as shown in Figure 4.13.
Note:
Keep control wires as short as possible and separate from high power cables to
minimize interference.
Step 1. Open the contact by inserting a small screwdriver into the slot above the
contact and push the screwdriver slightly upwards.
Figure 4.15. Connecting Control Wires.
Step 2. Insert the bared control wire into the contact.
Step 3. Remove the screwdriver to fasten the control wire into the contact.
Step 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 Chapter 8.5 Cable Specifications for control terminal wiring sizes and 6
Application Set-up Examples for typical control wiring connections.
4.8.3 Enabling Motor Operation (Terminal 27)
A jumper wire may be required between terminal 12 (or 13) and terminal 27 for the
adjustable frequency drive to operate if the drive is configured for External Inter-
lock.
• Digital input terminal 27 is designed to receive an 24 V DC external interlock
command. In many applications, the user wires an external interlock device to
terminal 27.
• When the status line at the bottom of the LCP reads AUTO REMOTE COAST or
EXTERNAL INTERLOCK [A60], this indicates that the unit is ready to operate but
is missing an input signal on terminal 27.
• When factory installed optional equipment is wired to terminal 27, do not
remove that wiring.
