Cable Connections (continued)

6. Connecting the Alarm I/O Terminals

Connect to the equipment with alarm input terminal using the alarm signal cable.

Cable

Flat-blade screwdriver

¥ The connector can be released by loosening the screws on the two sides as shown in the figure. ¥ Strip the coating of each cable by about 4 mm before inserting it. After connecting all of the cables, turn the screws on the side to fasten the

connectors.
