Powering
The EISB requires low-voltage power (AC or DC) via a four-pin removable
keyed connector. Power conductors can be stranded (16–18 AWG) or solid
(16–22 AWG). Consult the Specifications section for power requirements.
The various power options are explained below.
NOTE:
This device is intended for use with Class 2 circuits.
DC Powered
The EISB accepts a voltage range of 10–36 VDC and draws a current value
commensurate with 20-watt power consumption. Power conductors should be
sized accordingly. Ground is directly connected to zero volts and the
equipment chassis is isolated from zero volts. The input connections are
reverse-polarity protected.

Redundant DC Powered
Redundant diode-isolated DC power inputs are provided so the EISB can
operate despite the loss of primary power. Either source must be capable of
providing 20 watts of power.
