Ground Connecting
The DIS-700G-28XS must be properly grounded for optimum system performance.
Warning:
The middle grounding pin of the DC power terminal block has no function. The device
can only be grounded using the dedicated grounding screw.

The 24 V DC / 2 A alarm relay output contacts are located in a separate 2P terminal block. The alarm
relay contact is "Normal Open", and will automatically close when a power failure is detected.
Power Connecting
DC Power Connection
The switch can be powered using two power supplies (input range 20 V – 57 V) through the 3P
terminal block for DC power. 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.
After completing chassis installation, please apply power to the fused power distribution panel feeding
the chassis.
Note:
The DC power should be connected to a properly-fused power supply.
