WARNING

Electrical Shock Hazard.

Can cause severe injury, death or property 

damage.

Disconnect power supply before installation. Actuators 

with auxiliary switches can have more than one 

disconnect.

All wiring must comply with local electrical codes, ordinances 

and regulations. The ML6194/ML6294 are designed for use 

with a Class 2 power supply. Voltage and frequency of 

transformer used must correspond with characteristics of 

motor and those of power supply. See Fig. 5 for standard 

mechanical connection. See Fig. 6 through 9 for typical wiring 

diagrams.
