DMOC445 Manual and Operating Instructions
It is important to use the correct tightening hardware and install it correctly.

Above illustrations show a typical flat washer/lock washer/nut installation. It is important to ensure the
locking washer is fully compressed and is adjacent to the nut. After the terminal is completely assembled,
there should be a
minimum of two to three threads showing on the screw when the nut is properly
tightened.
The cable that connects the DMOC AC terminals to the electric motor should be shielded. This cable
shield should be properly terminated using a 360 degree connection to the DMOC terminal box cable
entrance fitting (See Figure 5 below). The rubber seal, which is a removable part of the entrance fitting,
should be slid underneath the cable shield as shown in Fig. 5 and Fig 6. Next slide the shield with rubber
seal (underneath) into the entrance fitting (see Fig 7). Ensure that the cable shield makes contact with
the fitting around the entire inside wall of the fitting (i.e. a complete 360 degree connection). Trim off
excess cable shielding such that no shielding extends into terminal box as shown in Fig 8. NOTE:
EXCESS SHIELDING INSIDE TERMINAL BOX CAN CREATE A ELECTRIC SHOCK HAZARD. Finally,
install the entrance fitting cap (nut, Fig 9) and tighten using a suitable wrench to ensure that adequate
compression of the rubber seal is achieved. Make sure to put the black plastic flange washer
