Page 6: Conduit Entry
Conduit Entry If you have purchased an enclosure without cable entries provided, you should add your own entry prior to mounting the termination box . CTC does not recommend putting holes in the top of the enclosure as it will cause restricted access to the wire termination connection points and also allow possible moisture ingress . -
Page 7: Grounding
Grounding Optional grounding is available on the TCT301 Series . Select the “with ground lug” option (TCT301G) when ordering if external grounding is desired . A. Mounting to Earth Ground When mounting TCT301G Series Termination 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 . -

Page 11: Post Installation Testing
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 . -
Page 12: Maintenance
Post Installation Testing The following LED Readout indicates the circuit integrity: Green LED: Normal . Indicates proper connection and an output bias will be given, indicating the health of the sensor (4 – 16 V indicates a healthy accelerometer) .
