Fit the attached mounting adapter into the fixing grooves on the top and
bottom faces of the rear case.

Push in the mounting adapter from the terminal side until it contacts the
panel to fix the main unit tentatively.

Fasten the fixing screws of the top and bottom mounting adapter
alternately as keeping balance little by little.
– Apply a fastening torque of 0.29 to 0.39 N•m.
Mounting the Terminal Cover
Slightly bend the E53-COV24 Terminal Cover to attach it to the terminal block as shown in the following diagram. The Terminal Cover
cannot be attached in the opposite direction.
Important
• For safety purposes, install the main unit where you are not able to touch the terminals when operating
the main unit. For example, install the main unit with the terminals hidden within the control board so
that a person working on the unit will not be able to touch live wires.
