. SSB1000 Series Modular Switch Box Overview: Four to 12 sensor inputs (four to 12 measurement channel outputs), fiberglass enclosure CTC modular switch box solutions allow for the monitoring of remotely-mounted vibration sensors, which would otherwise be restricted to human access due to safety considerations .
Mounting Instructions Note: If you have purchased a modular switch box without cable entries provided, you should add your own entry prior to mounting the modular switch box . CTC does not recommend putting holes in the top of the enclosure due to access and moisture concerns .
Conduit Entry If you are running conduit to your enclosure, ensure the conduit cable entry is located at the bottom of the enclosure when mounted . Note: To ensure moisture will not flow into the enclosure, a hole should be drilled at the lowest point in the conduit to provide drainage for any moisture .
Grounding Ensure the shield ground wire on the SSB1000 Series modular switch box is grounded to earth ground . A. Mounting to Earth Ground When mounting SSB1000 Series modular switch boxes to earth ground (such as an I-Beam), mount the shield ground wire using a mounting bolt through one of the mounting brackets on the enclosure .
B. Mounting to Non-Grounded Structure When mounting the modular switch box to a non-grounded structure, ensure the shield ground wire or customer-supplied ground wire is tied to a source of earth ground .

Post-Installation Testing The TM1018 Accelerometer Verification Meter can be used to verify cable conductivity, sensor location and proper wiring connections . The Verification Meter will indicate if the sensor, cable and/or junction box is in working condition . It will also confirm bias voltage of the accelerometer, which will inform you of the operation of the internal accelerometer amplifier .
