DANGER

THE MOTOR TERMINALS (U, V, W / T1, T2, T3) AND BRAKING RESISTOR

TERMINALS (R+ AND R- WHEN APPLICABLE) ARE LIVE WHEN THE

FREQUENCY CONVERTER IS CONNECTED TO A MAINS SUPPLY, EVEN WHEN

THE MOTOR IS NOT RUNNING. THE CONTROL BOARD’S RELAY OUTPUT

TERMINALS (WHEN APPLICABLE) MAY HAVE A DANGEROUS CONTROL

VOLTAGE, EVEN WHEN THE FREQUENCY CONVERTER IS DISCONNECTED

FROM THE MAINS SUPPLY. THESE CONDITIONS MAKE A RISK OF

ELECTRICAL SHOCK POSSIBLE.

WARNING

The RCD current from the frequency converter can exceed 3.5mA AC.

According to standard EN61800-5-1, a reinforced protective ground connection

shall be ensured to reduce the risk of an electrical shock.

4.3.4 Conductor diameter and stripping lengths

Use cables with heat resistance of at least 70°C.

4.3.5 Recommended tightening torques

The screw tightening torques of the power module terminals are 0.5 – 0.6 Nm and for control board’s digital input

terminals 0.5 Nm.

Note: Do not over tighten the terminal screws. Over tightening can cause the terminal block to break. If the terminal block

breaks, the entire frequency converter must be replaced.
