shield is installed just below the air bae. To install the mains
shield, use the following steps. Refer to Illustration 1.1 and
Illustration 1.2.
1. Remove the protective plastic lm from the front and
back of the upper mains shield and lower mains
shield.
2. Remove 14 brackets from the front edges of the
drive enclosure by removing 1 screw from each
bracket. See Illustration 1.1.
3. Install 14 new brackets from the mains shield kit.
Secure the new brackets to the drive enclosure using
14 M5x12mm screws (T25) from the kit. Tighten to
2.3 Nm (20 in-lb).
4. Feed the LCP (local control panel) cable through the
cable access hole in the upper shield. Refer to
