Making Power Connections
The power source used for the
Counterpart
must be properly grounded to an acceptable earth ground and the outlet
must be a grounded outlet. If the scale is remotely mounted, the platform must be separately grounded from the
chassis ground screw located on the bottom of the platform. Connect this screw with 18 gauge wire to the same
earth ground system as the AC power source. Failure to ground the base may cause static buildup that could cause
damage to the electronics and/or give incorrect weight readings.
The AC adapter plugs in and turns to lock to the unit. Figure 2-6 shows the AC power location.

Load Cell Wiring
On all complete units, the load cell has been wired to the CPU load cell terminal at the factory. Wire the cable to the
CPU board’s J1and J2 connector as shown in Table 2-1.
Note
If using a 4-wire connection, set J1 and J2 to ON. If using a 6-wire connection, set J1 and J2 to OFF.
