Danger
Electrocution Hazard. If the sampler is installed outdoors or in any wet or
potentially wet location, a Ground Fault Circuit Interrupter (GFCI) is required. If the
sampler is installed outdoors, over-voltage protection is required.
Note: Install the sampler on its own circuit to ensure a continuous, stable source of power.
Important Note: This product is not intended for use with a split-phase (3-wire,
single-phase, mid-point neutral) AC power system. Use this product only with a 3-wire
(Hot/Neutral/Ground) polarized AC power system. Be sure that access to the power cord
plug is not blocked or obstructed. The AWRS sampler is not provided with a power switch.
The cord plug serves as the local disconnect.
