follow the warnings indicated on the unit, as well as in the operating instructions.
Water and Moisture – Do not use the

Object and Liquid Entry – Care should
be taken so that objects do not fall, and
liquids are not spilled, into the enclosure
through openings.
Ventilation – When installing the unit in a
rack or any other location, be sure there is
adequate ventilation. Improper ventilation
will cause overheating, and can damage the

hold of the plug or cord if your hand is wet.
Always grasp the plug body when
connecting or disconnecting AC.
Grounding of the Plug – This unit is
equipped with a 3-wire grounding type
plug, a plug having a third (grounding) pin.
This plug will only fit into a grounding-type

contact your electrician to replace your
obsolete outlet. Do not defeat the purpose of
the grounding-type plug.

be mounted to a wall or ceiling using only
equipment designed for that purpose.
