NOTE: The Adept robot system is intended to be installed as a piece of
equipment in a permanently-installed system.
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, non-periodic 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.

DANGER: AC power installation must be performed by a
skilled and instructed person. During installation,
unauthorized third parties must be prevented from
turning on power through the use of fail-safe lockout
measures.
