Note

Some NTUs have non-standard connections and require special

cables. Consult the NTU maker’s product documentation

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 SN4900—

AC and DC units”)

• Connecting to an AC power source (see “Installing the power cables—AC units” on page 33)

• Connecting to a DC power source (see “Installing the power cables—DC units” on page 34)

Grounding the Model SN4900—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

2. Install the grounding wire between the grounding stud (see figure 11) and the grounding source.
