).
Bij de temperatuursensoren is de polariteit van de aders
niet van belang. De sensorkabels kunnen worden verlengd
tot 100 m (tot 50 m lengte = 0,75 mm
2
, tot 100 m =
1,5 mm
2
).
Alle sensorleidingen gescheiden verleggen van 230 V of
400 V voerende leidingen, om inductieve beïnvloeding te
voorkomen (min. 100 mm).
Afgeschermde laagspanningskabels gebruiken indien
externe inductieve invloeden kunnen worden verwacht
(b.v. door transformatorstations, krachtstroomkabels,
microgolven).
Brandveiligheidstechnische, bouwkundige maatregelen
mogen niet worden beïnvloed.
Kabel overeenkomstig aansluitschema aansluiten.
