Section 4: Wiring

Refer to wiring diagrams located at the back of this manual for wiring connections. Refer on
Figure 1 for location of enclosures and conduit entries. Use conduit and seals in accordance
with National Electric Code (NEC) and local codes.
4.0.1

Power Wiring

Connect power voltage leads to the circuit breaker located in the SCM. Power wires must
enter the SCM enclosure at the conduit entry on the lower right side of the SCM enclosure
to prevent water from entering the enclosure. The controller provides automatic phase
correction in case three phase power is connected in the wrong phase rotation.
4.0.2

SCM to AEE Wiring

Install conduits and seals between SCM and AEE as shown in the picture on Page 3 of
this manual. After wiring is complete, all seals must be filled with a water proof sealing
compound such as epoxy to prevent water from entering the AEE. Chico is not a waterproof
sealant and is not acceptable to be used alone. Chico with epoxy poured on top is
acceptable.
4.0.3

Motor Wiring

Connect three phase motor wires between the Motor Conduit Box (MCB) and the motor
overload relay located in the SCM. Connecting to the proper phase is important. Connect
two motor thermal wires between the MCB and SCM. Connect one motor thermal wire
to terminal 96 of the motor overload relay and connect the other wire to terminal 1 of P7
(Motor Protector) located in the SCM.
4.0.4

Sensor and Limit Switch Wiring

The position sensor and limit switches use low voltage signals that should be protected and
shielded from noise sources. Refer to wiring diagrams located at the back of this manual for
point to point connections. Connect shielded triad cable (3 wires) between the HPS located
AEE and connector P2 located on the TBM in the SCM. Use wire colors to ensure wires are
connected to the correct points. The cable should be Belden 22660 or equivalent triad
cable. Connect six wires between the limit switches, located in the AEE, and P1, located
on the TBM in the SCM. Use shielded multi-pair cable such as Belden 22639 or equivalent
cable with 3 twisted-pairs.
