2.1.3 Use of the 787 Series in Compliance with Underlying
Provisions
The 787 Series power supply system provides DC voltage to electric or electronic
devices, such as industrial control systems or display, communication and
measuring devices.
The devices have been developed for use in an environment that meets the IP20
protection class criteria. Protection against finger injury and solid impurities up to
12.5 mm diameter is assured; protection against water damage is not ensured.
Unless otherwise specified, operation of the components in wet or dusty
environments is prohibited.
The devices are designed for installation in an enclosure. Under no
circumstances may they be used in control systems for planes or in nuclear
facilities, as any malfunction in these applications could result in severe injuries
or risk of death.

Protect the components against materials having seeping and insulating
properties!
The components are not resistant to materials having seeping and insulating
properties such as: aerosols, silicones and triglycerides (found in some hand
creams). If you cannot exclude that such materials will appear in the component
environment, then install the components in an enclosure being resistant to the
above-mentioned materials. Clean tools and materials are imperative for
handling devices/modules.

The terms “switched ON” and “switched OFF”, as well as “tripped” are used in
this manual. To clearly delineate these terms, they are explained as follows:
Table 5: Definition of Terms
Designation
Definition
Switched ON
The user has activated the electronic circuit breaker
manually from the push and slide switch or via a
corresponding signal at the control input. The load
circuit is closed, the current flows.
Switched OFF
The user has deactivated the electronic circuit
breaker manually from the push and slide switch or
via a corresponding signal at the control input. The
load circuit is open, the current flow is interrupted.
Tripped
The electronics of the electronic circuit breaker has
been tripped due to overcurrent, undervoltage or
overvoltage. The load circuit is open, the current
flow is interrupted.
