ELECTRICAL INSTALLATION
SAFETY INFORMATION AND
GENERAL GUIDELINES
•
Make sure that the motor terminals are
configured for the correct supply voltage
•
Make sure that the input power supply is
isolated before making or changing any
connections
•
The control power supply and motor leads
must be laid separately. They must not be fed
through the same cable conduit/trunking and
should cross at 90° wherever this is
unavoidable
•
High voltage insulation test equipment must
not be used on any cables connected to the
inverter
Motors can be connected to inverters
either individually or in parallel. For
parallel motor operation each motor
should have an overload protection
relay fitted. Set parameter P077 to 0
for multi-motor operation mode.
For wiring guidelines to minimise the
effect of electro-magnetic
interference (EMI), refer to the
relevant section of this manual.
