Part 3 Mounting The Cabinet; Figure 1: Mounting The Cabinet - Chamberlain SENTEX Infinity Series Installation Instructions Manual

♦ This manual describes the "L" series (with telephone entry capability and a large display), since
this is the most complicated installation. The unit is shown with optional CCTV.
♦ If your system is a "B", "S", or "DI" series, skip the sections that do not apply.
NOTE: "B" series Infinitys with the built-in modem option may have a telephone interface board.
♦ To save space in this manual, some drawings are composites of several models.
Most Sentex Systems cabinet locks are commonly keyed, but can be easily replaced with
individually keyed locks by a locksmith.
♦ When mounting the cabinet, minimize disassembly of the unit, and take particular care to
handle of the circuit boards as little as possible.
♦ Ground yourself whenever you are handling the circuit boards. If no ground can be found,
attempt to discharge any static build-up before handling the boards.
♦ Never remove the display assembly from the faceplate. If you must remove the faceplate
for some reason, remove it as a complete assembly.
♦ If you must remove any other circuit boards, leave them assembled.
1. Remove the screw securing the lower right corner of the circuit board to the metal stand-off.
2. Remove the locking nut securing the circuit board and grounding lug to the upper left metal
stand-off.
3. Using a pair of needle nose pliers, compress the locking tab on the lower left plastic stand-off
while carefully lifting that corner of the circuit board. Repeat this step for the upper right plastic
standoff.
4. Carefully remove all cables connected to circuit board connectors, then remove the circuit
board from the cabinet and place on a smooth, clean surface.
