OPERATING MANUAL

17/48

Make sure that a differential switch (circuit breaker) has been installed upstream the line and that it functions properly.

Before carrying out any intervention on the electrical system, disconnect the power supply by means of main switch.

Work on the driver/fan by unqualified personnel or failure to comply with warnings can result in severe personal injury or serious

damage to material.

Only suitably qualified personnel trained in the set-up, installation, commissioning and operation of the product should carry

out work on the driver/fan. This driver must be grounded.

The power supply terminals L, N (1-Phase) or R, S, T (3-Phase) and the motor terminals U, V, W can carry dangerous voltages

even if the driver is inoperative.
