Additional terminal:
•
Two form C relay outputs. The location of the
outputs depends on the adjustable frequency
drive configuration.
•
Terminals located on built-in optional equipment.
See the manual provided with the equipment
option.

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 4.9.
NOTICE!
Keep control wires as short as possible and separate
from high power cables to minimize interference.
1. Open the contact by inserting a small screwdriver
into the slot above the contact and push the
screwdriver slightly upwards.

typical control wiring connections.
4.8.3 Enabling Motor Operation (Terminal
A jumper wire may be required between terminal 12 (or
13) and terminal 27 for the adjustable frequency drive to
operate when using factory default programming values.
NOTICE!
The adjustable frequency drive cannot operate without a
signal on terminal 27, unless terminal 27 is re-
programmed.

2. Insert the bare control wire into the contact.
3. Remove the screwdriver to fasten the control wire
into the contact.
4. Ensure that the contact is firmly established and
not loose. Loose control wiring can be the source
of equipment faults or less than optimal
operation.
27)
•
Digital input terminal 27 is designed to receive
24 V DC external interlock command.
•
When no interlock device is used, wire a jumper
between control terminal 12 (recommended) or
13 to terminal 27. This provides an internal 24 V
signal on terminal 27.
•
When the status line at the bottom of the LCP
reads AUTO REMOTE COAST, 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.
