2.2. Wiring

Each system is shipped with a wiring diagram which includes internal connections of the actuator.

These connections are for clarity and information only. Each wiring diagram may be generic or may be

project specific. Generic diagrams for each drive system are included in the appendix at the back of this

manual. If the wiring diagram is project specific, it will have the same number as the EIM Job Number.

2.2.1. Power Wiring

Power wires must be sized for the rated motor voltage and current in accordance with NEC. Refer to

EIM Job Specification sheet for motor current requirements. Power to the actuator is connected to L1,

L2 and L3 terminals in the M2CP enclosure.

2.2.2. Control Wiring

Control wires connect to terminals on P4 of the TBM in the M2CP and on various terminals of the VFC

drive depending on the drive model. These wires control when the drive operates, as well as the

direction and speed. They are open collector inputs on the drive, the M2CP sinks these to the drive

logic common. Control wires should be 20AWG or larger shielded cable. Terminal points on P4 of the

TBM are defined below.
