Alarm Output Wiring (/A1 to /A3, Option)
WARNING
• To prevent electric shock, ensure the main power supply is turned OFF.
• If a voltage of more than 30 VAC or 60 VDC is to be applied to the alarm output
terminal, use ring-tongue crimp-on lugs with insulation sleeves on all terminals
to prevent the wires from slipping out when the screws become loose.
Furthermore, use double-insulated wires (dielectric strength of 2300 VAC or
more) for the signal wires on which a voltage of more than 30 VAC or 60 VDC is
to be applied. For all other wires, use basic insulated wires (dielectric strength
of 1350 VAC). To prevent electric shock, attach the terminal cover after wiring
and make sure not to touch the terminals.
Wiring Procedure
1.
Turn OFF the recorder and remove the cover for the option terminal.
2.
Connect the alarm output wires to the terminal.
The terminal arrangement will be one of the figures shown below depending on
the alarm output relay option (number of outputs) and the /F1 option.
3.
Replace the terminal cover and fasten it with screws.
Note
The option terminal block itself can be removed by loosening the two screws at the top left
and bottom right of the terminal block. This makes wiring work easier. To prevent bad
contacts, make sure to securely tighten the screws after wiring.
