the two (2) slots at the bottom of that section of the enclosure (middle or bottom).

3. Push the top of the panel forward until it is properly set in position.

4. Use a T30 Torx screwdriver to tighten the two (2) M6 Torx screws under the top lip of the panel.

Note

The TOP and BOTTOM rear panels are re-attached in exactly the same way. Use

the following procedure to re-attach each of the rear panels in its turn.

The instructions for re-attaching the rear panels are the reverse of the instructions

for removing rear panels. Refer to the graphic on page 15.

Note

After installation, the TOP rear panel MUST be removed whenever the ground and
