5.15 Re-fitting the Door
Before replacing the door ensure all mains, zone, alarm and auxiliary wiring has been completed and
will not foul the door when it is refitted.
Replace the plastic door by raising the door and placing flush to the back-box of the panel (figure
5.12 step 1). Slide the door down and ensure it pushes fully home into the back-box (figure 5.12 step
2). Finally screw in the fixing screw, taking care not to over tighten the screw (figure 5.12 step 3)
