WARNING
The wiring must comply with all applicable regulations. The type and position of the fused isolators
must also comply with regulations. For safety reasons, these must be clearly visible and installed
within operating distance of the machine. All machines must be earthed throughout.
IMPORTANT
Operating a machine with the wrong voltage or with excessive phase asymmetry represents incorrect
use, which is excluded from the PicoEnergy guarantee. If the phase asymmetry exceeds 2 % (voltage)
and 1 % (current), please contact your power supply utility immediately, before commissioning the
heat pump.
