Chapter 2: Site Preparation and Installation
We recommend that you provide a 10-A fuse on your external DC connection to
safeguard against connecting the power source with the incorrect polarity.
The SafeGuard Controller does not have a power switch. To be able to disconnect the
power cords when needed, make sure that the power connections are easily accessible.
Make sure that the AC power input source connection is within 8 feet of the SafeGuard
Controller installation location.
