Retain for future use.HAZARD CATEGORIES AND SPECIAL SYMBOLS
Read these instructions carefully and look at the equipment to become
familiar with the device before trying to install, operate, service or maintain it.
The following special messages may appear throughout this bulletin or on the
equipment to warn of potential hazards or to call attention to information that
clarifies or simplifies a procedure.
The addition of either symbol to a “Danger” or “Warning” safety label
indicates that an electrical hazard exists which will result in personal injury if
the instructions are not followed.
This is the safety alert symbol. It is used to alert you to potential personal
injury hazards. Obey all safety messages that follow this symbol to avoid
possible injury or death.
DANGER
DANGER indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.
WARNING
WARNING indicates a potentially hazardous situation which, if not
avoided, can result in death or serious injury.
CAUTION
CAUTION indicates a potentially hazardous situation which, if not
avoided, can result in minor or moderate injury.
CAUTION
CAUTION, used without the safety alert symbol, indicates a potentially
hazardous situation which, if not avoided, can result in property damage.
NOTE:Provides additional information to clarify or simplify a procedure.
PLEASE NOTE
Electrical equipment should be installed, operated, serviced, and maintained
only by qualified personnel. No responsibility is assumed by Schneider
Electric for any consequences arising out of the use of this material.
FCC NOTICE
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
(cid:129) Reorient or relocate the receiving antenna.
(cid:129) Increase the separation between the equipment and receiver.
(cid:129) Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
