2.1.2 Personnel Qualifications
All sequences implemented on 787 Series devices may only be carried out by
electrical specialists with sufficient knowledge in automation. The specialists
must be familiar with the current norms and guidelines for the devices and
automated environments.

2.1.3 Use of the 787 Series in Compliance with Underlying
Provisions
The EPSITRON®787 Series power supply system provides direct current 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 and 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 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 787-1668 electronic circuit breaker reliably protects up to 8 load circuits
against short circuiting and overloading. The 24 VDC input voltage is distributed
among 8 output channels, each of which can be provided with separate fuse
protection.
