Installing the SVI II AP Display Cover
NOTE After replacing the SVI II AP display cover you must power up the
unit (see “Powering Up the SVI II AP” on page
52).
The replacement display cover is shipped with a lanyard to prevent the cable (that connects from
the display to the terminal board) from breaking. The lanyard must be inserted under the screw
in the lower left corner that attaches the terminal board to the SVI II AP housing.
To install the cover:
1. Install the lanyard and tighten the screw to 5 in/lb.
2. Using the 3 mm hex key, remove the screw from the lower left corner, connecting
the terminal board to the SVI II AP housing.
3. Connect the cable from the display into the LCD connector on the terminal board.
4. Ensure that the gasket is in its groove in the housing.
5. Place the cover over the screw mounts.
6. Tighten the four screws with the 5 mm hex key.
7. After installing the new display, power up the unit (refer to “Powering Up the SVI II
AP” on page 52 for further information).
NOTE The cover of the SVI II AP is a critical component for safety in
Hazardous Areas. To ensure safe operation the flat surfaces of the
cover and the housing must be clean and absolutely free of
particles or dents. There must be no gap between the housing
and cover; torque spec is 50 in/lb.
Ensure that:
1. The gasket is seated in the groove in the housing flange.
2. No wires or retaining cable can be trapped under the cover flange.
3. The flange area is not corroded and the surface is not scarred.
4. The four cover bolts are securely tightened to 50 in/lb.
