Installing Your 1394 Ground
Clamps
The 1394 ground clamp kit is designed for use with 1394C-SJTxx-x
(Series C) system modules and 1394C-AMxx (Series C) axis modules
only.
To install your system or axis module ground clamp:
1. Prepare one end of the cable for attachment to the cable shield
clamp by removing the outer insulation and braided shield from
the cable. Ensure approximately 51 mm (2.0 in.) of the insulated
cable wires are exposed (refer to Figure 1).
2. Remove another 22 mm (.875 in.) of insulation to expose the
braided shield underneath for clamp attachment.
Important: When cutting into the insulation use care not to cut
into the braided shield underneath.
3. Position the cable shield clamp over the exposed braided shield
(ensure clamp screw is behind clamp and not braided shield).
4. Tighten the clamp screw.
Important: Do not overtighten the clamp screw or damage to
the braided shield may result.
5. Thread the bracket screw into the bottom of the module and
tighten.
