ELECTRIC CONNECTION
CHAPTER 4
Ensure tension and frequency of pump (read motor plate) and supply network are same.
WARNING
Installer must make sure that electric current network has ground wire conforming to current laws.
Make sure that electric current network is provided with a high-sensitivity circuit-breaker
∆=30 mA (DIN VDE 0100T739).
DANGER - ELECTRIC SHOCK RISK

BIOX® range pumps have a built-in thermal overload with automatic reset. Further protections are not required.
BIOX® range three phase pumps can be protected by using a magneto-thermic motor protector or a contactor with thermal relay;
in both cases they have to be rated conforming to nominal power showed on motor plate.
Eventual electric float switch must be connected to auxiliary connector buckles.
Water head and delivery are terribly effected by wrong rotation of shaft of pump motor. Clock wise rotation is correct (upside view of
pump). When startin the pump motor will ungergo an anti-clock wise back-kick.
In this case test is positive; on contrary case, please disconnect pump from network and inverse two phases.
Single phase pumps are equipped with double ground contact plug at top end of supply cord ; in this case grounding is done when
plugging in.
In this case the ground wire (yellow-green cable) of supply cord must be connected to ground wire of electric current network.
Ensure connection to electric current network by using an omnipolar-sectionned magneto thermic circuit-breaker.
This will ensure effective disconnection from electric current network.
