Electrical connection
Attention
Before connection, check whether the mains voltage required by the JUDO UNIDOS
digital dosing pump system matches the local circumstances!
The electrical connection of the JUDO UNIDOS digital dosing pump system must only be
performed by JUDO customer service or authorised technical personnel!
Once the mains voltage is connected, the JUDO UNIDOS digital dosing pump system
can start up automatically, therefore only plug in the mains plug upon commissioning!
Do not operate the JUDO UNIDOS digital dosing pump system by switching the mains
voltage on or off as this can damage the pump electronics!
If external circuits are connected to the signal inputs of the dosing pump, they must be
isolated from dangerous voltages using double/additional insulation!
The degree of protection (IP 65/Nema 4X) is only ensured if protective caps or
connection plugs are correctly fitted!
