Electrical Installation
Important
Electrical ratings are subject to changes. Refer to serial plate decal for electrical ratings information specific to your machine.
WARNING
Hazardous Voltage. Can cause shock, burn or cause death. Allow machine power to remain off for two minutes prior to working in and around AC inverter drive.
WARNING
Hazardous Voltage. Can cause shock, burn or death. Verify that a ground wire from a proven earth ground is connected to the lug near the input power block on this machine.
The AC inverter drive requires a clean power supply free from voltage spikes and surges. If a transformer or generator is connected to the building's power supply, always install line reactors before the terminal block connections to the machine. A voltage monitor should be used to check incoming power. The customer’s local power company may provide such a monitor.
If input voltage measures above 240V for a 220V drive or above 480V for a 400V drive, ask the power company to lower the voltage. As an alternative, a
The AC drive provides overload protection for the drive motor. However, a separate single or
IMPORTANT: Do NOT use fuses in place of a circuit breaker.
For installation in the United States or Canada, branch circuit protection must be provided according to National and Local Codes. The branch circuit breaker must be of the inverse time or instantaneous trip type at the values given in the technical specifications for each machine.
Use a circuit breaker of the minimal type of 10kA interrupt current.
CAUTION
Do not use a voltage or phase converter on any variable speed machine.
The
-In accordance with legal regulations, every machine must be protected with an earth leakage circuit breaker of 30mA.
-The earth leakage circuit breaker, which one uses, must be of the type SI.
-For countries outside the European Community, the usual safety instructions must be observed.
