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.

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 supported by 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 box or

screwed onto the housing of an automation device.

The devices employ pluggable WAGO picoMAX

connectors, enabling them to

be pre-wired for quicker installation and faster device replacement.
