this equipment.

Read the installation instructions before you connect the system to its
power source.
Warning
Before working on equipment that is connected to power lines, remove
jewelry (including rings, necklaces, and watches). Metal objects will heat
up when connected to power and ground and can cause serious burns or
weld the metal object to the terminals.

cause severe bodily injury and equipment damage.

The plug-socket combination must be accessible at all times because it
serves as the main disconnecting device.

To prevent the switch from overheating, do not operate it in an area that
exceeds the maximum recommended ambient temperature of 113×F (45×C).
To prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance
around the ventilation openings.
Warning
The device is designed to work with TN power systems.

When installing the unit, the ground connection must always be made first
and disconnected last.
