3.2.4 Alarm Output Wiring
1 Make sure the power switch is turned OFF and remove the transparent cover at the rear
of the
µ
R1800.
2 Connect the alarm output wires to the alarm output terminal. Do NOT change the place
of the therminal block!
3 Replace the transparent cover.
Depending on your option, your alarm output terminal will be arranged like one of the
following:
!
CHARACTERISTICS:
Output type:
relay transfer contact (energize/de-energize type switchable)
Output capacity:
250VAC (50 or 60Hz), 3A
250VDC, 0.1A (resistive load)
Dielectric strength: 1500VAC (50 or 60Hz) for one minute between output terminal
and ground terminal
To adjust initial settings, see 9.1.
• To prevent an electric shock, ensure the main power supply is turned OFF
during wiring and ensure the ground terminal is connected using a class 3
resistance of 100
Ω
or less.
• Ensure the ground terminal is connected using a class 3 resistance of 100
Ω
or
less.
• Use "crimp-on" lugs with insulation sleeves for all connections if a voltage of
more than 30 VAC or 60 VDC is applied to the alarm output or fail/memory end
output. Furthermore, use doubleinsulated wires (withstand voltage
performance: more than 2300VAC) for those wires which apply 30 VAC or
60VDC. All other wires can be basic-insulated (withstand voltage performance:
more than 1350VAC). To prevent electric shock, do not touch the terminal after
wiring and make sure to re-attach the cover.
NOTE
To prevent an emission of electromagnetic disturbances, separate the alarm output wires
from the power supply and input wires at least 0.1m. Over 0.5m is recommended.
