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 SN4300—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 SN4300—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
