Operating on non-standardized voltages
For measurement tasks on voltages that are outside the normal mains voltage ranges
(e.g. <90 VAC) and operation on DC (max. 28 VDC) the R&S
ENV216 control circuit is
powered by an external power supply.
1. Make sure that the DC voltage does not exceed 28 VDC. Higher DC voltages may
damage the equipment.
2.
DANGER!
Risk of electric shock. Make sure that the external power supply com-
plies with the requirements for reinforced/double insulation in accordance with
DIN/EN/IEC/UL/CSA 61010-1, DIN/EN/IEC/UL/CSA 60950-1 or
DIN/EN/IEC/UL/CSA 62368-1. An external power supply without reinforced/double
insulation is live in case of failure. Touching a live electrical device causes serious
personal injury, or even death.
Connect the external power supply to the "EXT. POWER SUPPLY" socket (1).
The input is reverse voltage protected.
