Operating Instructions, 03/2022, C79000-G8976-C617-03
Note
The requirements of EN61000-4-5, surge immunity tests on power supply lines, are met
only when a Blitzductor is used with 24 VDC:
BVT AVD 24

Supply voltage
WARNING
Power supply
The device is designed for operation with a directly connectable safety extra-low
voltage (SELV) or protective extra low voltage (PELV) from a limited power source
(LPS).
The power supply therefore needs to meet at least one of the following conditions:
•
Only safety extra low voltages SELV/PELV with limited power source LPS complying
with IEC 62368-1 / EN 62368-1 / VDE 62368-1 may be connected to the power
supply terminals.
•
The power supply unit for the device must meet NEC Class 2 according to the
National Electrical Code (r) (ANSI / NFPA 70).
If the equipment is connected to a redundant power supply (two separate power
supplies), both must meet these requirements.
Grounding
WARNING
Danger to life from overvoltage, fire hazard
When using outdoor antennas, the shared or grounded pin of the circuit must be
connected to the shield of the coaxial cable and to all touchable conductive parts and
circuits. Otherwise, there may be impermissibly high voltages on touchable parts in the
event of a fault.
