DC Power Connection
A removable terminal block on the top panel provides both power and
alarm connections. Power can be provided through the dual inputs from
separate sources (PWR1 & PWR2). One power supply is enough to
power up the device. If two power supplies are used, the device
provides power redundancy function. See the figure provided below for
recommended DC power wiring scheme.
