Section 2: M2CP Electrical Hook-Up
Remove PWR and TBM covers to expose terminals for customer wiring. BETTIS Modular
Modular Control Package (M2CP) is available configured in many combinations of electrical
and electronic parts. Refer to WIRING DIAGRAM and BETTIS JOB SPEC SHEET for
components provided by BETTIS. Connect control wires to TBM and Power (motor) Voltage
to PWR terminals. If optional M2CP mounted circuit breaker was specified, connect power
voltage leads to circuit breaker. BETTIS terminal blocks are furnished with wire binding
screw connectors with rising captive plates, allowing field connection by several methods:
1) strip and connect bare wire, 2) strip and install wire ferrule, 3) strip and install crimp-on
insulated or non-insulated ring tongue or similar terminal. Circuit Breaker accepts 1) bare
wire strip, or 2) wire ferrule.

STEP 1. Move valve to mid-position by handwheel. This will allow sufficient time
to stop actuator in case of improper hook-up or reversed incoming power voltage
phases.
STEP 2. Identify a means of removing power from actuator during check out.
Be sure no erroneous remote control signal can be received causing actuator to
energize.
STEP 3. Energize Open control to check operation of contactor and pushbuttons.
Open controls must move valve in Open direction. If valve Closes, actuator must
be stopped and any (2) two power voltage leads reversed to correct voltage
phasing.
CAUTION:
If voltage is improperly phased, Torque and Position Limit Switches are not in
circuit to protect valve.
STEP 4. Seal all field conduit entries in accordance with National Electric Code.
