Wire Specifics
Wires connecting to J1, J2, J3, or J4 should adhere to the following specifications:

Cable Grounding
Except for the power cord, all cables should be grounded against the scale enclosure. Do the following to ground
shielded cables.
•
Use the lockwashers, clamps, and kep nuts provided in the parts kit to install grounding clamps on the
enclosure studs. Install grounding clamps that will be used; do not tighten nuts.
•
Route cables and grounding clamps to determine cable lengths required to reach cable connectors. Mark
cables to remove insulation and shield as described below:
•
For cables with foil shielding, strip insulation and foil from the cable half an inch (15 mm) past the
grounding clamp (see Figure 2-4). Fold the foil shield back on the cable where the cable passes through
the clamp. Ensure silver (conductive) side of foil is turned outward for contact with the grounding clamp.
•
For cables with braided shielding, strip cable insulation and braided shield from a point just past the
grounding clamp. Strip another half inch (15 mm) of insulation only to expose the braid where the cable
passes through the clamp (see Figure 2-4 on page 9).
•
Finish installation using cable mounts and ties to secure cables inside of indicator enclosure.

Serial Communications
Wire the serial communications cables to J4, which is Port 2 (5-wire RS-232 port). J5 is Port 1 (RS-232 and 20
mA). Connect communications cables to J5 and J4 as shown in Table 2-3.
Use cable ties to secure serial cables to the inside of the enclosure.
Port 1 supports full duplex RS-232 communications only; Port 2 provides either active 20 mA output or duplex
RS-232 transmission. Both ports are configured using the SERIAL menu. See Section 3.6.5 on page 36.
