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 cover plate.
3. Remove security cables (this will void NTEP Certification).
4. Remove screws on the summing board cover plate 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.
