Depending on the external wiring, dangerous voltages [115 V, 220 V or 230 V]
may be present on the terminals of relay outputs RO1 to RO3 or on the optional
AGPS board (Prevention of unexpected start-up).
•
The Prevention of unexpected start-up function (option +Q950
remove the voltage from the main and auxiliary circuits.
•
The Safe torque off function (option +Q968) does not remove the voltage from
the main and auxiliary circuits.
•
At installation sites above 2000 m (6562 ft), the terminals of the RMIO board
and optional modules attached to the board do not fulfil the Protective Extra
Low Voltage (PELV) requirements stated in EN 50178.
Grounding
These instructions are intended for all who are responsible for the grounding of the
drive.
WARNING! Ignoring the following instructions can cause physical injury, death or
equipment malfunction and increase electromagnetic interference.
•
Ground the drive, the motor and adjoining equipment to ensure personnel
safety in all circumstances, and to reduce electromagnetic emission and
interference.
•
Make sure that grounding conductors are adequately sized as required by
safety regulations.
•
In a multiple-drive installation, connect each drive separately to protective
earth (PE).
•
Do not install a drive with EMC filter option +E202 on an ungrounded power
system or a high resistance-grounded (over 30 ohms) power system.
Note:
•
Power cable shields are suitable for equipment grounding conductors only
when adequately sized to meet safety regulations.
•
As the normal leakage current of the drive is higher than 3.5 mA AC or 10 mA
DC (stated by EN 50178, 5.2.11.1), a fixed protective earth connection is
required.
