Perform following steps for assembly of plug half (male) coupling in fixed plate:

A.  Insert plug body in respective hole in movable plate such that shoulder of the plug body is rested  

against plate surface.

B.  Install Jam Nut on plug half from opposite end of plate and screw nut in clock-wise direction.
C.  Hold Jam nut in position by using standard tool and inserting it in slots provided on Nut.
D.  Using standard wrench, hold hex on end connection of coupling and rotate in clockwise direction  

to apply torque as per above chart.

9.0 OPERATING

Figure 5.  Operating multiplate coupling

As shown in figure 5, two plates of assembly play major role in operation of connection and disconnection. Fixed plate 

with lever and cover, and movable plate. Movable plate has plug (male) half and fixed plate has socket (socket) half.

1.  First step is to open cover/dust cap and clean plate surface from any dust/foreign particles.
