Connecting power
In connecting to the power source, it is important to establish a good grounding connection first, then the
power connection. This section explains:
• Making the ground connection for either AC or DC units (see section “Grounding the Model SN4400—
AC and DC units”)
• Connecting to an AC power source (see “Installing the power cables—AC units” on page 31)
• Connecting to a DC power source (see “Installing the power cables—DC units” on page 32)
Grounding the Model SN4400—AC and DC units
Do the following:
1. Assemble a ground wire using #10 AWG wire with green-colored insulation and two ring terminals. Make
the wire long enough to reach one of the following earth ground sources:
– The building ground rod (generally located at the site’s main service entrance)
– A sprinkler system pipe
– A cold-water pipe
– Building structural steel
