Product # 7774

ERMINAL

The Terminal Box provides easy, reliable connections for splicing wires and

cables. All connections are housed in a weather-resistant enclosure. The termi-

nal box can simplify and speed up the task of wiring the weather station sen-

sors, sensor interface module (SIM), and communication lines.

Note:

The terminal blocks in the Terminal Box are rated for 300V, 10A and are intended for 26-16 AWG

(.08-1.5 mm) wire. When wiring, all applicable building and electrical codes must be followed.

When connecting shielded cables to shielded cables, connect each colored wire

to the same colored wire on the extension cable (or other cable). In twisted-pair

cables, all black wires are ground and may be shorted together.

When connecting standard cables to standard cables, you may also connect

each colored wire to the same colored wire on the extension cable (or other

cable). In some cases, however, wires may be combined in order to use fewer

terminals on the terminal block. Consult the table below:
