Mounting Instructions Stainless steel mounting brackets are included on the enclosure . Wall anchoring screws are not included . Note: If you have purchased a SCE400 Series enclosure without cable entries provided, you should add your own entry prior to mounting the enclosure .
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 . Correct Incorrect Drill Drain Hole Here Figure 4. Conduit Entry for SCE400 Series...
Grounding Ensure the shield ground wire on the SCE400 Series enclosure is grounded to earth ground . A. Mounting to Earth Ground When mounting SCE400 Series enclosures 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 SCE400 Series enclosure to a non-grounded structure, ensure the shield ground wire or customer-supplied ground wire is tied to a source of earth ground . Figure 6. Ground Wire Placement...
Electrical Connectons Cables enter and exit the enclosure through conduit fittings or cord grips on the bottom of the unit . All input and output wiring is connected to the terminal blocks and signal conditioners inside the unit . Inputs are routed through a conduit fitting or cord grips (one per channel), output wiring is routed through a conduit fitting .

Note: When collecting waveform data from the BNC jack on the signal conditioner using a portable data collector that supplies constant current power, it is recommended that the data collector is configured so that power to the sensor is turned off . Although the BNC connector circuitry offers short circuit protection and can safely sink the current, long-term degradation may occur due to increased power dissipation depending on the magnitude of the IEPE current .

A short circuit is indicative of a lack of electrical resistance, removing the ability to measure the impact from a change in voltage . This instance is largely driven by an incorrect wiring setup . Verify that all wiring connections are attached in the correct polarity, and that no signal and common wires are touching .

This state occurs when the signal conditioner starts up, confirms there is an available configuration, and sets up its peripherals and outputs . If the USB cable is connected and plugged into a PC, this state will persist . Plugging in the USB cable at any point will also cause the device to enter this state .
