Installation, Mechanical

52120:
The 52120 can be installed indoors or outdoors.
52121:
The 52121 is designed for installation in control panels or
similar applications.
To install the 52121, follow these instructions:
1. Drill a hole (diameter at least 6.5 mm, 9/32 in) for the
axle of the throttle knob. Pull the throttle knob and the
graduated dial face off the unit.
2. Drill two holes for the mounting screws. Insert the
axle of the throttle knob from below through the hole
drilled in step 1. Use two M3 screws to secure the
throttle from above.
Attention! The screws must not protrude more than
4 mm (3/16") from the heat sink. If they protrude further
or press on the circuit board, the circuit board will be
damaged.
3. Glue the graduated dial face onto the face of the con-
trol panel and press the throttle knob onto the throttle.
Attention! Make sure the heat sink is ventilated. If the
throttle is installed in a closed housing, provide adequa-
te ventilation holes. When installing several throttles
52121 next to each other, make sure there is a space of
at least 5 mm between the heat sinks.
