OWER DOWN AND DISCONNECT THE POWER CORD BEFORE SERVICING OR WIRING THE
SWITCH
.
Do not disconnect modules or cabling unless the power is first switched off.
The device only supports the voltage outlined in the type plate. Do not use any other
power components except those specifically designated for the switch device.
Disconnect the power cord before installation or cable wiring.
The switches can be powered by using the same DC source used to power other devices. A
DC voltage range of 10 to 30 VDC (3.0W) must be applied between the V1+ terminal and
the V1- terminal (PW1), see the following illustrations. A Class 2 power supply is required
to maintain a UL60950 panel listing. The chassis ground screw terminal should be tied to
the panel or chassis ground. A redundant power configuration is supported through a
secondary power supply unit to reduce network down time as a result of power loss.
