Safety
Warning
Only trained and qualified personnel should be allowed to install,
replace, or service this equipment.
Warning
Ultimate disposal of this product should be handled according to
all national laws and regulations.
Warning
This unit is intended for installation in restricted access areas. A
restricted access area is where access can only be gained by
service personnel through the use of a special tool, lock and key,
or other means of security, and is controlled by the authority
responsible for the location.
Warning
Unplug the power cord before you work on a system that does not
have an on/off switch.
Warning
The plug-socket combination must be accessible at all times
because it serves as the main disconnecting device.
Warning
The safety cover is an integral part of the product. Do not operate
the unit without the safety cover installed. Operating the unit
without the cover in place will invalidate the safety approvals and
pose a risk of fire and electrical hazards.
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.
