Grounding the Model 2160 and connecting power
In connecting to the power source, it is important to establish a good grounding connection first, then the
power connection. 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 6) and the grounding source.
3. Connect the power adapter to the DC 9V port on the Model 2160, and then connect to the power source.
Mains Voltage: Do not open the case the when the power cord is attached.
Line voltages are present within the power supply when the power cords are
connected. The mains outlet that is utilized to power the device shall be
within 10 feet (3 meters) of the device, shall be easily accessible, and pro-
tected by a circuit breaker.
The Model 2160 is not shipped with power cables. For AC powered units,
ensure that the power cable used meets all applicable standards for the coun-
try in which it is to be installed, and that it is connected to a wall outlet which
has earth ground.
The power supply automatically adjusts to accept an input volt-
age from 100 to 240 VAC(50/60 Hz).
