Communication Lightning Protection
1 Precaution
CAUTION The COM connection for communications is not the shield wire. The COM, RX, and TX wires must connect to each other at all controllers.
CAUTION Connect the safety ground wire to one of the grounding terminals!
- Install the lightning protector in series on the cable leading from the controllers to the multiplexer. Locate the protector close to the controller. Install a good ground; otherwise, protection is not effective.
- Connect the side marked “Protected” to the controller side. Connect the side markers “Unprotected” to the other side of the cable, leading to the multiplexer.
- Use 3 wire shielded cables (3 + shield) for the communication line. Connect the shielded wire to the safety ground terminal.
CAUTION Do not ground the shield of the protected side.
