Planning the electrical installation
Connection of a motor temperature sensor to the drive I/O
WARNING!
IEC 60664 requires double or reinforced insulation between live parts
and the surface of accessible parts of electrical equipment which are either non-
conductive or conductive but not connected to the protective earth.
To fulfil this requirement, the connection of a thermistor (and other similar
components) to the digital inputs of the drive can be implemented in three alternate
ways:
1. There is double or reinforced insulation between the thermistor and live parts of
the motor.
2. Circuits connected to all digital and analog inputs of the drive are protected
against contact and insulated with basic insulation (the same voltage level as the
drive main circuit) from other low voltage circuits.
3. An external thermistor relay is used. The insulation of the relay must be rated for
the same voltage level as the main circuit of the drive. For connection, see the
Firmware Manual
.
Installation sites above 2000 m (6562 ft)
WARNING!
Wear appropriate protection when installing, operating or servicing the
RMIO board wiring and optional modules attached to the board. The Protective Extra
Low Voltage (PELV) requirements stated in EN 61800-5-1 are not fulfilled at altitudes
above 2000 m (6562 ft).
Routing the cables
Route the motor cable away from other cable routes. Motor cables of several drives
can be run in parallel installed next to each other. It is recommended that the motor
cable, input power cable and control cables be installed on separate trays. Avoid
long parallel runs of motor cables with other cables in order to decrease
electromagnetic interference caused by the rapid changes in the drive output
voltage.
Where control cables must cross power cables make sure they are arranged at an
angle as near to 90 degrees as possible. Do not run extra cables through the drive.
The cable trays must have good electrical bonding to each other and to the
grounding electrodes. Aluminium tray systems can be used to improve local
equalizing of potential.
