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.
Cet appareil numérique de la classe B respecte toutes les exigences du Règlement sur le matériel brouilleur du Canada.
Caution The nonmetallic enclosure does not provide grounding between conduit connections. Use grounding type bushings and jumper
wires.
Attention Un boîtier nonmétallique n’assure pas la continuité électrique des conduits. Utiliser des manchons ou des fils de accord
spécialement conçus pour la mise á la terre.
