Emergency Stop Devices
The overall design of the installation must include emergency stop devices and any
other safety equipment that may be needed. Pressing STOP on the drive's control
panel does NOT:
• Generate an emergency stop of the motor.
• Separate the drive from dangerous potential.
Input Power Cables/ Wiring
Input wiring can be either:
• A four conductor cable (three phases and ground/protective earth) routed through
conduit.
• Four insulated conductors routed through conduit.
Size wiring according to local safety regulations, appropriate input voltage and the
drive's load current. In any case, the conductor must be less than the maximum limit
defined by the terminal size (see "Drive's Power Connection Terminals" on page
227).
The table below lists copper and aluminum cable types for different load currents.
These recommendations apply only for the conditions listed at the top of the table.
Based on:
• EN 60204-1 and IEC 60364-5-2/2001
• PVC insulation
• 30 °C (86 °F) ambient temperature
• 70 °C (158 °F) surface temperature
• Cables with concentric copper shield
• Not more than nine cables laid on cable ladder
side by side.
