Hardware Installations
2-5
Be sure to disconnect the power cord before installing and/or wiring your switch.
Be sure of the maximum possible current when wiring connections. If the current goes above
the maximum ratings, the wire could overheat and result in serious damage to your switch.
2-6.3 Wiring The Alarm Relay
The alarm relay contact can be wired into an alarm circuit which senses an alarm condition when the contact
is broken. The alarm relay is normally closed when there is no alarm condition. Please note that the alarm
relay contact can only support
1A current at 24VDC (1A@24VDC).
Do not apply voltage and current that
exceed these specifications.
The acceptable wire range is 12 to 24 AWG.
2-6.4 Wiring the Earth Ground
An earth ground connector is provided on the top panel with an earth ground sign next to it. Grounding the
device can help to release leakage of electricity to the earth safely so as to reduce injuries from
electromagnetic interference (EMI).
Prior to connecting to the power, it is important to connect the ground wire to the earth. Follow steps below to
install ground wire:
