4.8.2 Wiring to Control Terminals
Control terminal connectors can be unplugged from the
frequency converter for ease of installation, as shown in
Illustration 4.9.
For details about STO wiring, refer to chapter 6 Safe Torque
Off (STO).
NOTICE
Keep control cables as short as possible and separate
them from high-power cables to minimize interference.

See chapter 9.5 Cable Specifications for control terminal
cable sizes and chapter 7 Application Examples for typical
control cable connections.
4.8.3 Enabling Motor Operation
(Terminal 27)
A jumper wire is required between terminal 12 (or 13) and
terminal 27 for the frequency converter to operate when
using factory default programming values.

Loosen the screws for the terminals.
Insert sleeved control cables into the slots.
Fasten the screws for the terminals.
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.
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. The jumper provides an
internal 24 V signal on terminal 27.
