Installation & Wiring
Control Wiring
Requirements
•
Run all signal wiring in either a shielded cable or separate metal conduit.
•
Do not exceed control wiring length of 20 meters (65.6 feet).
•
Use Belden 8760 (or equivalent) –18 AWG (0.750mm
2
), twisted pair, shielded or 3 conductor.
•
Avoid crossing the power lines or motor lines with the control wires. If they must cross, ensure that they
cross at right (90
o
) angles.
•
If using transistor outputs 11 or 12, with an inductive load such as a relay, install a recovery diode parallel
to the relay as shown in Figure 2.6, to prevent damage to the output.
Control Terminal Block Wiring Specifications
Note: 0.75mm
2
(18 AWG) wire must be used for the alarm relay. Torque the mounting screw
to: 0.5-0.6 Nm (4.4-5.3 in lb).

ATTENTION
A hazard of electrical shock, death or equipment damage exists.
Control terminals are isolated but not tied to earth ground. If
terminal (L) on the control terminal block is not grounded,
exposed conductors, shields or metal conductors can be at
hazardous voltage levels.
Failure to observe this precaution could result in severe injury or
loss of life.

IMPORTANT: Only one frequency
source may be connected at a time.
If more than one reference is
connected at the same time,
an undetermined frequency

To improve noise immunity, the
common (terminal L) must be
connected to ground terminal/
protective earth.

Notes: 1. Parameter C13 is NC. This input must be active
(jumpered) for the drive to run. See following pages
for description of these settings.
2. A contact closure on terminals 3 and P24 is required
for the controller to respond to a Start/Run command.
