2.1.3 Use of the 787 Series in Compliance withUnderlying
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 designedfor 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.

The Compact Power Series are compact switched-mode power supply units with
a wide range of uses. Their stepped design makes them suitable for applications,
such as for use as a DIN-rail built-in installation device in accordance with
DIN 43880, and this is also supportedby conformity with EN 60335-1.
The power supply units can be fitted on a DIN-rail. Screw mounting using the
fastening clips supplied with the device is also a possible alternative. In this way,
devices can be fitted both in the control cabinet as well as in a distribution boxor
screwed onto the housing of an automation device.
The devices employ pluggable WAGO picoMAX®connectors, enabling them to
be pre-wired for quicker installationand faster device replacement.
