WARNING
  • Risk of electric shock.
  • Disconnect the power supply before making electrical connections. The printed circuit board and its components are at AC line voltage. Contact with components carrying hazardous voltage can cause electric shock and may result in personal injury or death.
Avertissement
  • Risque de décharge électrique.
  • Débrancher l'alimentation avant de réaliser tout raccordement électrique. Le circuit imprimé et ses composants présentent une tension CA. Tout contact avec des composants porteurs de tensions dangereuses risque d'entraîner une décharge électrique et de provoquer des blessures graves, voire mortelles.
Important:
  • Use the M4 x 8 crosshead terminal screws provided. Substitution of other screws voids the warranty and agency approvals.
  • To prevent moisture from entering and condensate from forming inside the Type 3R/IP43 enclosure, do not block the drain hole provided.
  • To prevent moisture from entering and condensate from forming inside the Type 4/IP67 enclosure, do not remove the case-to-cover O-ring provided on the flow switch.
  • Use copper conductors only. Make all wiring in accordance with local, national, and regional regulations.
  • Do not exceed the control’s electrical ratings. Exceeding the control’s electrical ratings can result in permanent damage to the control and void any warranty.

The F261 models have three color-coded terminals. Red is common. See Figure 1 and Table 1 for switch action.
