Mains connection
CAUTION
Only qualified electricians are permitted to perform electrical installations!
The following components have to be provided in the installation:
• A readily accessible circuit breaker, rated according to the FertiKit™'s total rated power certified as a
branch circuit over current protector (see Appendix - Dosing booster electrical data , page 46),
compliant with the national code and requirements.
• Grounding connection: ≤ 10 Ω.
For the selection of the wire size - consider (see Appendix - Dosing booster electrical data , page 46):
• The FertiKit™'s total rated power.
• Whether the electricity supply is single-phase or three-phase.
(if a dosing booster is not present in the system, select the single-phase, up to 1.5 kWatt option).
