Emergency Stop Devices; Input Power Cables/ Wiring - ABB ACS550-01 User Manual

220

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 any of:
• A four conductor cable (three phases and ground/protective earth). Shielding is
not required.
• 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
223).
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.
