5. Connect the load side of the
drive short circuit protective
device to terminals 181 (R),
182 (S) and 183 (T) on the
faceplate of the controller or
through the optional
Disconnect Kit if used. See
Figure 3-12.
DANGER
THE DISCONNECT KIT IS A
CONVENIENCE DISCON-
NECT ONLY. IT IS THE US-
ERS RESPONSIBILITY TO
PROVIDE THE REQUIRED
DRIVE SHORT CIRCUIT
PROTECTION. FAILURE TO
OBSERVE THIS PRECAU-
TION COULD RESULT IN SE-
VERE BODILY INJURY OR
LOSS OF LIFE.
Note:
Drive short circuit protection
must be provided by the customer
with a UL listed or CSA certified
fuse or circuit breaker in a circuit
with maximum available
symmetrical short circuit current
equal to or less than 5000 Amps.
Select a drive short circuit
protective device from columns 1,
2, 3, or 4 of Table 3-1.
The optional Disconnect Kit is a
convenience disconnect only and
does not provide the required
drive short circuit protection.
Depending on the application, the
drive short circuit protection may
be the same device as that
required by the National Electical
Code.
6. Connect the normally closed
motor thermostat to pins 40
and 41 of connector 2CN as
shown in Figure 3-12.
CAUTION
If the motor thermostat is not
properly wired, the controller
will not stop when the contact is
opened. Failure to observe this
precaution could result in dam-
age to, or destruction of, this
equipment.

Make Control and Signal
Wiring Connections
Note:
Signal wiring must be
soldered to the mates that connect
to the two connectors located on
the face of the controller hinged
panel. The mating connectors and
sleeve tubing are supplied with the
controller. Refer to Table 7-5 for
sequencing and encoder cables
with a connector on one end and
terminal boards on the opposite
end for control cabinet mounting
that are available from Reliance
Electric. Encoder signals terminate
at the motor through an MS
connector. The mating MS
connector is supplied with the
motor. Refer to Table 7-5 for
available Reliance encoder cable
kits that have a pre-soldered MS
connector on one end and
provisions for either a connector or
wire lugs on the opposite end.
1. Use a minimum of #22 AWG
twisted wire (Reliance part
number 417900-76EAD or
equivalent) having two to three
twists per inch.
2. Follow the below procedures
for routing wiring:
•
Be sure all control and signal
wiring is physically isolated
from power wiring. Current in
power circuits can induce
voltages in signal wiring.
•
Run encoder wiring in a
dedicated separate steel
conduit (steel or flexible
armored steel).
•
Do not route signal wiring
through junction or terminal
boxes that contain power or
control wiring.
•
Have control wiring and
encoder wiring intersect
power wiring at a 90-degree
angle.
•
Do not route signal wiring
near devices producing
external magnetic fields.
