User Manual

When connecting the wires to the terminal blocks, make sure the metal wire ends

and the terminal blocks completely touch. Then, tighten the screws securely. Failure

to properly tighten can result in an electrical short and burning of the terminal blocks.

Connect the power at the lower right side of the unit to the terminal block. Each pair

of Ll and L2 should have its own corresponding double polled breaker. Note that the

ECO 180 unit will be connected to two double pole circuit breakers while the EC0270

unit will be connected to three double pole circuit breakers (Fig.14).
