DANGER:
Never attempt to view optical connectors that might be emitting laser energy.
Do not power up the laser product without connecting the laser to the optical fiber and
putting the cover in position, as laser outputs will emit infrared laser light at this
point.
Connecting the Power
The switch can be powered using two power supplies (input range 12V – 58V). Insert the positive and
negative wires into the V+ and V- contacts on the terminal block and tighten the wire-clamp screws to
prevent the wires from being loosened.
NOTE:
The DC power should be connected to a properly-fused power supply.
Connecting the Alarm Relay
The alarm relay output contacts are in the middle of the DC terminal block connector as shown in the
following figure.
By inserting the wires and setting the DIP switch of the Port Alarm to “ON”, the relay output alarm will detect
any port failures, and form a short circuit.
The alarm relay out is “Normal Open”.
