Note: 1.
The relay in the 61F-GP-N8H de-energizes when there is water present across the electrodes, whereas the relay in the 61F-GP-N8HY
energizes when there is water present across the electrodes.
2.
The length when using completely-insulated, 600-V, 3-conductor (0.75 mm
2
) cabtyre cables. Usable cable lengths will become shorter
as the cable diameter or number of conductors becomes larger.
3.
The insulation resistance and dielectric strength indicate values between power terminals and electrode terminals, between power ter-
minals and contact terminals, and between electrode terminals and contact terminals.
4.
Possible to use with 10 kΩ or less, however, this may cause reset failure.
