Locate the circuit breaker that will be using the MMS. The intended circuit breaker must be within visual range of the switch (MMS functions with trip units that have the Short-time Zone Selective Interlocking (ST-ZSI) capability).
Install the MMS I-Line Enable Module according to the I-Line Enable Module installation instructions.
Prepare the intended circuit breaker. Follow the instructions provided with the circuit breaker for all PPE, safe electrical work practices, and hazard messages.
1. Remove the plastic cover of the circuit breaker (P- or R-Frame). The number of fasteners will vary depending on the frame size of the circuit breaker.
2. Remove the connector block from the top of the trip unit.
3. Locate the "Z" connections of the trip unit (typically the left-most section of the 12-pole connector located on the top of the trip unit).
4. Provide wires from the Z3 and Z4 connections and route them through the wiring conduit provided on the left-most portion of the molded case of the circuit breaker. Provide a 2 in. jumper between the Z5 and Z3 connection locations. Refer to Connector Usage Information for wire size and strip length details. (The wire length should be in excess of the wire-routing path distance from the circuit breaker to the MMS I-Line Enable Module).
5. You can also provide 24 VDC power to the trip unit by connecting to the "F" connections (typically the right-most section of the 12-pole connector located on the top of the trip unit).
6. Provide wires from the F1 and F2 connections and route them through the wiring conduit provided on the left-most portion of the molded case of the circuit breaker. Refer to Connector Usage Information for wire size and strip length details. (The wire length should be in excess of wire-routing path distance from the circuit breaker to the MMS I-Line Enable Module).
7. Replace the connector on the top of the trip unit.
8. Replace the plastic cover of the circuit breaker.
Connect the wires from Z3 and Z4 (described in step 3-d above) to the MMS I-Line Enable Module ZSI connections (refer to GDE8239900—MMS I-Line Enable Module (240, 480, and 600 VAC) for location). Refer to Connector Usage Information for wire size and strip length details.
Connect the wires from F1 and F2 (described in step 3-f above) to the MMS I-Line Enable Module 24 VDC output connections (refer to GDE8239900—MMS I-Line Enable Module (240, 480, and 600 VAC) for location). Refer to Connector Usage Information for wire size and strip length details.
