a.   Feed motor (53) lead wires into capacitor box 

cover (9). Care should be taken not to damage 
lead wires. Assemble cover on housing (42), 
aligning dowel pins (27) with bore in cover and 

flats of limit switch shaft (22) with bore and slot 

in end of screw (62).

NOTE

Limit switch shaft should be able to spring up when a 

light pressure with finger is applied downward on limit 

switch nut and removed.

 

b.  Install lock washers (8) and button head cap 

screws (7).

 

c.  Feed motor lead wires (red and blue small 

terminal ends only) into cover switch box through 
5/8” diameter hole. Install terminal of red lead 
wire on normally closed terminal of left side 
of switch. Install terminal of blue lead wire on 
normally closed terminal of right side of switch. 
(Wires going to switches should be same color.) 
It may be necessary to install terminals on switch 
terminals tabs with needle-nose pliers and care 
should be taken not to damage terminal tab or 
switch (see Figure 6-3).

 

d.  Feed terminal wires, (17) red, (18) blue, fuse 

jumper wire, and motor lead through 1/2” tapped 
hole in cover capacitor box outside of cover.

 

e.   Moving wires out of the way, insert capacitor (5) 

into box (termials up) and attach motor lead wire 
(large connectors) to capacitor terminals. (Red 
on one pair of capacitor terminals and blue on 
the other pair of capacitor terminals.)

 

f.   Insert insulation (4) and assemble gasket (3) and 

cover (2) with screws (1).

 

g.   Adjust actuator limit switch settings per 

instructions in paragraph 2-2.

 

h.  If actuator has potentiometer, refer to position 

indicator installation and calibration instructions 
in Paragraph 2-4.

 

I.  Attach gasket (12) and cover (11) with 

screws (1).

ASSEMBLY IS COMPLETE.
