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. 50 VDC) the R&S
ENV216
control circuit is powered by an external power supply.
1. Make sure that the DC voltage does not exceed 50 VDC. Higher DC voltages
may damage the equipment.
2.
DANGER!
Risk of electric shock. Make sure that the external power supply
complies 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 cau-
ses serious personal injury, or even death.
Connect the external power supply to the "EXT. POWER SUPPLY" socket (1).
The input is reverse voltage protected.
