amperes (rms) at 600 V maximum when protected with the fuses given in section
Fuses, page 150.
Disconnecting device (disconnecting means) – See chapter Planning the
electrical installation, page 69.
Ambient conditions – The drive is to be used in a heated indoor controlled
environment. For the specifications, see Ambient conditions on page 162.
Input cable fuses – For installation in the United States, branch circuit protection
must be provided in accordance with National Electrical Code (NEC) and any
applicable local codes. To fulfil this requirement, use the US fuses given in section
Fuses, page 150.
For installation in Canada, branch circuit protection must be provided in accordance
with Canadian Electrical Code and any applicable provincial codes. To fulfil this
requirement, use the UL classified fuses given in section Fuses, page 150.
Power cable selection – See chapter Planning the electrical installation, page 69.
Power cable connections – For the connection diagram and tightening torques,
see Electrical installation.
Control connections – For the connection diagram and tightening torques, see
Electrical installation.
Overload protection – The drive provides overload protection in accordance with
the National Electrical Code (US). See the Firmware Manual for setting. Default
setting is off, must be activated at start-up.
