Grounding Transient Protection
To ensure proper operation, the JB8SP and JB8SPT must be grounded to protect the junction box from stray volt-
age and is essential for operation of the DC transient protection incorporated into the junction box.
A ground wire has already been attached to the grounding lug located on the main board and extends out of the
junction box cord grip. Securely attach a 10 gauge ground wire to the ground wire that's already coming out of
the junction box. The final ground wire connection must be at the AC power supply ground terminal and is sepa-
rate from the truck scale ground.
Figure 4-2 illustrates an example of single point grounding of junction box and the truck scale.
