Cautions
For the contacts being connected to the external drive terminals, use contacts of a switch, a relay, or the like
which is driven by lower than 30V AC or 60V DC or use manual contacts.
4-3-4 Alarm output terminals
(Caution 1) The alarm output is a mechanical relay “a” contact output. For connections, refer to
[3. Connections of output relay terminals].
Cautions
1. Connect a load of less than the designated contact
capacity to the output relay terminals.
2. Turn off the feed power source and buffer relay
power supply before starting connections for
preventing an electric shock accident.
①
Connect output relay terminals to the load via a
buffer relay.
②
For connection to the output terminals, use crimp
style terminals each having an insulation sleeve.
3. The buffer relay power supply is applied to the
output relay terminals after connections and an
electric shock accident occurs if you should touch
these terminals. Mount a terminal cover without fail
after connections.
