5. Push the plastic bushing all the way into the enclosure to make a tight seal in the hole.

Figure 2-5. Use Plastic Bushings

Bushings are not a “cord grip.” Bushings allow for free movement of cable while protecting them from the
enclosure sides.

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.

If using a 4-wire connection, set J1 and J2 to ON. If using a 6-wire connection, set J1 and J2 to OFF.
