Preparation of the safe:
The holes necessary to mount the lock and entry device correspond with the standard dimensions for mechanical locks.
The spindle hole must be deburred with no sharp edges.
1 Drill mounting holes for US 8-32 or M4 screws and a cable hole, see Figure 1 .
2 Using the two (2) 8-32 mounting screws mount the dial plate (P/N 3752) onto the tapped holes on the door.
3 The dial plate must be centered over the spindle hole. The dial plate should be mounted with the arrows in the up
position.
• Tapped holes on the door should be at 12:00 and 6:00 locations, see
Figure 4 .

INSTALLING THE KEYPAD
1 Cut the square spindle to length (1.06 [26.9240mm] + door thickness). Thoroughly deburr.
2 Insert the spindle into the center of the keypad assembly making sure that the cable is routed in the groove of the
spindle,
see Figure 5 .
3 Route the cable either under the spindle or between the circuit board and the spindle.
• Figure 6 shows and example of Right-Handed or Vertical-Up positioning.
• Figure 7 shows an example Left-Handed or Vertical-Down positioning.
NOTE: It is important to make sure the cable will not rub on the dial plate after assembly.
4 Install the cable protector on the entry over the spindle and cable and install over the large and small pins on the
housing.
• It is important to make sure the cable will not rub on the dial plate after assembly, see
Figure 5 .
5 Feed the cable and the spindle through the spindle hole on the door.
6 Place the shoulder bushings in the holes of the dial plate and rotate the keypad so that the keypad is aligned correctly,
see Figures 8 and 9 .
7 Install the cable clamp over the cable and the spindle on the inside of the door with the flat side facing the door.
8 Slide down to the spindle hole to protect the cable from rubbing on the edge of the hole, see Figure 10 .
9 Gently pull on the cable to assure that there is no excess cable in the spindle hole that would rub on the metal door.
! Route the cable on the notch of the cable clamp as shown, see Figure 10 .
