Installation 3
2.3 Summing Board Security
After an NTEP inspector has examined the unit, he/she will install security cables on the summing board cover.
These cables prevent the summing board from being tampered with by an unauthorized individual. If these
cables are removed, NTEP Certification will become void.
Figure 2-2. Summing board cover with security cables installed
2.4 Electrical Interface to Indicator
Twenty feet of 6-wire cable to connect the scale to the weight indicator is supplied with each scale. Both ends
have the wires stripped and tinned.
To access the summing board,
1. Remove the stainless steel platform.
2. Remove lid in the center of the platform, revealing the summing board coverplate.
3. Remove security cables (this will void NTEP Certification).
4. Remove screws on the summing board coverplate and remove lid.
Wire Connections
Remove the summing board cover and connect the wires to the INDICATOR terminal (Figure 2-3). To connect
the indicator wires to the appropriate connectors, push in the quick connect lever with a small screwdriver or
ballpoint pen. When holding the lever, insert the appropriate wire into the exposed wire opening.
