Chapter 3: System Installation
Facility Overvoltage Protection
The user must protect the robot from excessive overvoltages and voltage spikes. If the country
of installation requires a CE-certified installation, or compliance with
IEC 1131-2, the following
information may be helpful: IEC 1131-2 requires that the installation must ensure that
Category II overvoltages (i.e., line spikes not directly due to lightning strikes) are not exceeded.
Transient overvoltages at the point of connection to the power source shall be controlled not to
exceed overvoltage Category II, i.e., not higher than the impulse voltage corresponding to the
rated voltage for the basic insulation. The user-supplied equipment or transient suppressor
shall be capable of absorbing the energy in the transient.
In the industrial environment, nonperiodic overvoltage peaks may appear on mains power
supply lines as a result of power interruptions to high-energy equipment (such as a blown fuse
on one branch in a 3-phase system). This will cause high current pulses at relatively low
voltage levels. The user shall take the necessary steps to prevent damage to the robot system
(such as by interposing a transformer). See
IEC 1131-4 for additional information.
