Electrical Installation

The most important part of the electrical installa

-

tion is the power supply for the actuator.

1. Unscrew the actuator wiring cover in order to 

access to the terminal block(s) as shown 

below.

2. Perform the wiring of actuator using Figure 

13 to Figure 15 as per the required 

application.

3. If necessary, use the appropriate electrical 

cable conduits and cable gland to properly 

secure the actuator wiring.

4. Replace the wiring cover once done. 

Actuator Run modes

The function selection switch (see Figure 16) can

be used to place the actuator into any one of two

different modes:
•

Modulating run mode 

•

Floating/2-position run mode

•

Service/Off mode.

Caution:  To avoid personal injury 

(electrical shock) and to prevent 

equipment damage, before 

installation, you must remove power.
