• Use M4 screws provided in the parts kit to install shielding clamps on the grounding rail at the back of the enclosure
• Install only the necessary amount of shielding clamps for the cord grips to be used
• Remove the insulated jackets and shielding per the following instructions
Shielding Procedure
1. Install the shielding clamps on the grounding rail using the clamp screws. Finger tighten the screws at this time.
2. Route the cables through the cord grips and the shielding clamps to determine the cable lengths required to reach the
appropriate cable connectors.
3. Mark cables to remove the insulated jacket as described below for Foil Shielded Cables and Braid Shielded Cables.
Foil Shielded Cables
Figure 2-10. Foil Shielded Cable
1. Strip the insulated jacket and foil 1/2 in (15 mm) past the shielding clamp.
2. Strip another 1/2 in of the insulated jacket, leaving the foil shielding exposed.
3. Fold the foil shielding back on the cable where the cable passes through the clamp.
4. Ensure the silver (conductive) side of the foil is turned outward.
5. Wrap the shield wire around the cable, ensuring it contacts the foil where the cable passes through the clamp.
6. Torque the shielding clamp screw to 10 in-lb (1.1 N-m), ensuring the clamp is around the cable and contacting the
shield wire.
Braid Shielded Cables
Figure 2-11. Braid Shielded Cable
1. Strip the insulated jacket and braided shielding from a point just past the shielding clamp.
2. Strip another 1/2 in (15 mm) of the insulated jacket, leaving the braid exposed where the cable passes through the
clamp.
3. Torque the shielding clamp screw to 10 in-lb (1.1 N-m), ensuring the clamp is contacting the braided shielding of the
cable.
NOTE: The recommended cable strip length is 0.25 in (7 mm) for all 380/380X/381 connectors.

2.8.1 Load Cell Cable
To attach the cable from a load cell or junction box, route cable to the YC3 connector. See Table 2-6 for wiring the load cell cable
from the load cell or junction box to connector.
NOTE: For a 4-wire installation leave pins 3 and 4 empty on the connector.
NOTE: For a 6-wire installation set SW2 to all positions “off”, for 4-wire installation set all positions to “on.”
2.8.2 380/380X RS-232 Serial Communications
The CN10 connector is intended to provide a connection point for the RS-232 serial communications. One RS-232 port is
available. See Table 2-7 for the pin assignments for the CN10 connector.
NOTE: This connection is available on the outside of the 381 enclosure via an RJ-11 connector and optional
cable (PN 215273). The serial connection can be made directly to the CN10 connector if the RJ-11 connection is not wanted.
