Bering BEXP05i Manuel D'installation Et D'utilisation page 27

NOTE:
(1) Above electrical wiring diagram only for your reference, please subject machine posted the wiring diagram.
(2) The swimming pool heat pump must be connected ground wire well, although the unit heat exchanger is
electrically isolated from the rest of the unit. Grounding the unit is still required to protect you against short circuits
inside the unit. Bonding is also required.
Disconnect: A disconnect means (circuit breaker, fused or un-fused switch) should be located within sight of and
readily accessible from the unit. This is common practice on commercial and residential heat pumps. It prevents
remotely-energizing unattended equipment and permits turning off power at the unit while the unit is being
serviced.
6.2 Electrical protection
The power supply for the heat pump must come, preferably, from an exclusive circuit with regulatory protection
components (30mA differential protection) and a magneto-thermal switch.
- The electrical installation must be carried out by a specialized professional (electrician) in accordance with the
standards and regulations in force in the country of installation.
- The heat pump circuit must be connected to a safety earth circuit at the terminal block.
- The cables must be properly installed to prevent interference.
- The pump is intended for connection to a general power supply with earth connection.
- Section of the cable; This section is indicative and should be checked and adapted according to the needs and
conditions of use.
- The tolerance of acceptable voltage variation is +/- 10% during operation.
The connections must be dimensioned according to the power of the device and the state of
installation.

These values are given as a guideline, only an authorised electrician can determine the values
corresponding to your installation. The electric cable must be equipped with a ground connection and
with a circuit breaker with difference 30mA.
