Connecting the Alarm Relay Wires to the Craft Interface in an EX9200 Switch
Before you connect the alarm relay wires between a switch and an alarm-reporting
device:
•
Ensure you understand how to prevent electrostatic discharge (ESD) damage. See
“Prevention of Electrostatic Discharge Damage” on page 351.
Ensure that you have the following parts and tools available:
•
ESD grounding strap
•
2.5 mm flat-blade screwdriver
To connect the alarm relay wires between a switch and an alarm-reporting device (see
Figure 59 on page 195):
1. Prepare the required length of replacement wire with gauge between 28 AWG
(0.08 mm
2
) and 14 AWG (2.08 mm
2
).
2. Insert the replacement wires into the slotsin the front of the block. Use the screwdriver
to tighten the screws and secure the wire.
3. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the
ESD points on the chassis.
4. Plug the terminal block into the relay contact, and use the screwdriver to tighten the
screws on the face of the block.
5. Attach the other end of the wires to the external device.
