SAMI GS

Safety Instructions

ONLY A COMPETENT ELECTRICIAN SHOULD CARRY OUT THE ELECTRICAL INSTALLATION

SAMI GS must always be earthed through an earthing conductor connected to the earthing terminal (Protective Earth PE).

If SAMI GS is connected to a system without system earth, the earth fault protection must be capable of starting at earth fault currents containing high frequency and DC components. SAMI GS' earth fault protection guards the frequency converter only against earth faults occuring in the motor or the motor cable.

Fault current circuit breakers do not necessarily operate properly with frequency converters. Circuit breaker function should be checked for possible earth fault currents arising in a fault situation.

Warning symbols

For your own safety please pay special attention to instructions containing these symbols.

Dangerous voltage

General warning

WARNINGS!

SAMI GS contains dangerous voltages when connected to the mains.

Note that the printed circuit cards within the Converter Module of the SAMI GS are at mains supply voltage potential.

The capacitors in the Converter Module are charged to dangerous DC voltage levels. After disconnecting the supply, wait at least 5 minutes after the display readout on the

control panel has disappeared before taking any measurements.

Dangerous external control voltages may be present on the relay outputs of the Control Interface Card and Option Cards.

Pay attention to the following instructions:

- Do not work on the frequency converter when SAMI is connected to the mains.

- Never connect mains voltage to the drive output terminals (U2, V2, W2).

- Do not make any voltage withstand tests on any part of the unit. Disconnect motor cables before taking any measurements on the motor or motor cables.

- Make sure that power factor correction capacitors are not connected between the drive and the motor.

- Do not touch the IC-circuits on the printed circuit boards. Static discharge voltage may destroy the circuit. In general, avoid touching any of the components within SAMI GS.

- Check that the voltage setting of the internal transformer corresponds to the mains voltage.

ALWAYS CHECK THAT SAMI GS IS SAFE BY MEASURING THE DC LINK VOLTAGE BETWEEN TERMINALS UDC+ AND UDCAND MAINS INPUT VOLTAGE!

The meter for measuring these voltages must withstand 1000 V DC or AC. Refer to the figure 5-1 on page 20.
