Preparing for Installation

Before installing/repairing any wiring to the 8620 DET, make sure that the power is turned off at the main circuit breaker or switch. The power switch should be locked in the OFF position and labeled to prevent other personnel from turning the power on during installation.

Do not apply power until the 8620 DET is properly grounded.

Do not apply power in a hazardous environment until the cover is closed.

Incorrect field wiring connections can damage the 8620 DET electronics and cause system malfunctions.

Unpacking

Varec’s 8620 DET(s) are shipped fully assembled and ready for installation.

To unpack the 8620 DET, follow the steps below:

1.Place the shipping container on a secure bench.

2.Open the shipping container, taking care not to damage the contents.

3.Carefully remove the 8620 DET from the shipping container and place it on the bench.

4.Inspect the 8620 DET for shipping damage. Report any damage to the carrier and Varec.

Note If the 8620 DET must be stored prior to installation, it should be repacked in its ship- ping container and stored in a temperature-and-humidity-controlled environment.

Installation

To install the 8620 DET, follow the steps below:

1.Verify proper 8620 DET configuration for the RS-232, RS-422/485, or Ethernet protocol.

2.Ensure proper grounding of the 8620 DET. Refer to Figure 2-1 below for dimensions and mounting holes.

3.Verify that there is proper mounting height for your application (trucks, cars, and pedestri- ans).

4.Install proper mounting hardware (pole, stand, or wall).

5.Install the 8620 DET to the mounting hardware.

6.Run the conduit and wiring to the 8620 DET.

7.Power up and verify communications.
