The E024U board is powered by a high efficiency switching
power supply that takes 115VAC input and provides 36VDC to
power the board. On the power supply board there is only one
repleaceble fuse:
6.3A timed
The E024U board allows the connection of a 24V backup bat-
tery to provide power to operate the gate during blackouts. For
more details about how the boards handles the loss of main
power and how to configure its behaviour please see par 4.3

AC POWER GUIDELINES:
THE E024U control board and power supply uses a single
phase AC power line to operate, charge the batteries, and power
gate accessories. Use the following guidelines when installing
the AC power:
1. Check the local wiring codes in all cases and follow all local
building codes. Wiring and hookup should be performed by a
qualified electrician/installer only.
2. AC power should be supplied from a circuit breaker panel and
must have its own dedicated circuit breaker. This supply must
include a green ground conductor.
3. Use copper conductor wires with liquid tight flexible conduit
UL listed for electric cable protection
14 AWG, 600V, 80°C

4. Properly ground the gate operator to minimize or prevent
damage from power surges and/or lightning. Use a grounding
rod if necessary. A surge suppressor is recommended for ad-
ditional protection.
