When installing and using this electrical equipment,
basic safety precautions should always be followed,
including the following:
The installer must ensure that this control and its
wiring are isolated and/or shielded from strong
sources of electromagnetic noise. Conversely, this
Class B digital apparatus complies with Part 15 of
the FCC Rules and meets all requirements of the
Canadian Interference-Causing Equipment
Regulations. However, if this control does cause
harmful interference to radio or television
reception, which can be determined by turning
the control off and on, the user is encouraged to
try to correct the interference by reorienting or
relocating the receiving antenna, relocating the
receiver with respect to this control, and/or
connecting the control to a different circuit from
that to which the receiver is connected.
CAUTION:
The non-metallic enclosure does not
provide grounding between conduit connections.
Use grounding type bushings and jumper wires.
CAUTION:
Improper installation and operation of
this control could result in damage to the equip-
ment and possibly even personal injury. It is your
responsibility to ensure that this control is safely
installed according to all applicable codes and
standards. This electronic control is not intended
for use as a primary limit control. Other controls
that are intended and certified as safety limits
must be placed into the control circuit.
