Important Notes

Usage for the intended purpose

Use power supply unit URN 2 only for the voltage supply of a maximum of four
switching controllers type NRS 2-4 or NRS 2-5 and the cycling timer PRS 9.

Safety note

The equipment may only be installed by qualified staff.
Qualified staff are those persons who – through adequate training in electrical

engineering, the use and application of safety equipment in accordance
with regulations concerning electrical safety systems, and first aid & accident
prevention – have achieved a recognised level of competence appropriate to
the installation and commissioning of this critical safety device.

Danger

The terminal strip of the URN 2 is live during operation. This presents the
danger of electric shock. Cut off power supply before opening the
equipment and before inserting or removing the 19" slide-in unit.
