The speed control is designed to operate within a temperature range of 

–40 to +75 °C (–40 to +167 °F). Mount the control in a location with space for 

adjustment and wiring access. If mounted on the prime mover, do not expose the 

speed control to sources of radiant heat such as exhaust manifolds or 

turbochargers. Also choose a protected location so that the control won’t be 

damaged when moving the prime mover or when equipment is moving near by. 

Mount the control close to the actuator and battery to meet the wire length 

requirements. Allow for adequate ventilation. 

The EPG speed control must be mounted on a metal plate that is at the same 

ground potential as the case. The case and mounting plate must be grounded to 

either the protective earth of the building or, if no protective earth is available, the 

frame ground of the engine/skid. 

Actuator Mounting and Linkage 

MOUNTING SCREWS 

0.250-20 (inch) thread. Minimum mounting screw 

engagement should be 9.5 mm (0.375 inch). 

Torque screws to 9–11 N·m (80–100 lb-in). Use 

star washers between the screw heads and 

control body to break paint and ground the 

EPG chassis to the mounting plate.

Actuator location must allow installation of a 

suitable linkage. The actuators are designed 

to operate within a temperature range of –40 

to +93 °C (–40 to +200 °F). Do not expose 

the actuator to sources of excessive heat. 

Match the actuator’s direction of rotation for 

increased fuel with the fuel control’s direction 

of rotation for increased fuel by choosing a 

suitable linkage.
