. The TSB4000 Series 12 Switched Triaxial Channel stainless steel modular switch box is used to convert the four-conductor input wiring of up to 12 remotely installed triaxial accelerometers to switched BNCs and a switched four-pin connector for 36 channels of measurement .
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 drilling 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 enters from 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 TSB4000 Series modular switch box is grounded to earth ground . A. Mounting to Earth Ground When mounting TSB4000 Series modular switch boxes to earth ground (such as an I-Beam), no additional steps are necessary, as the enclosure is grounded internally .
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 .
