6.3 AROUND THE DOOR
The door and jamb are crucial to the integrity of the Double Electrically Isolated (DEI) Enclosure. The
following must be properly set up for the door assembly to be effective:
• The inner and outer shields must be separated electrically.
• The pressure of the three latching bars on the roller cam ramps must be firm and equal. Adjust the
ramps as required; adding shim stock under the ramps can increase the pressure on the latching
bar.
• The threshold of the doorjamb must be level. If necessary, use wood shims to level the threshold.
