Safety & Warnings
This unit has been designed and tested according to safety standards and left the manufacturer’s premises in a compliant state. To maintain this state and ensure safe operation, the following instructions and precautions should be observed:
1) When permanently cabling the unit, connect the protective ground conductor before making any other connections.
2) Built-in units should only be operated when properly fitted into the system.
3) For permanently cabled units without built-in fuses, automatic switches, or similar protective facilities, the AC supply line should be fitted with fuses rated to the units.
4) Before switching on the unit, ensure that the operating voltage set at the unit matches the line voltage. If a different operating voltage is to be set, use a fuse with the appropriate rating.
5) Units of protection class I with a disconnectible AC supply cable and plug may only be operated from a power socket with a protective ground contact. The protective ground connection should not be made ineffective by an extension cable. Any breaking of the protective ground conductor within or outside of the unit or loosening of the protective ground connection may cause the unit to become electrically hazardous. The protective ground conductor shall not be interrupted intentionally.
6) Before opening the unit, isolate it from the AC supply. Adjustment and replacement of parts, as well as maintenance and repair, should be carried out only by specialists approved by R&S. Observe safety regulations and rules for the prevention of accidents. Use only original parts for replacing parts relevant to safety (e.g., power on/off switches, power transformers, or fuses).
7) Also observe the additional safety instructions specified in this manual.
