HiPath Wireless Outdoor AP Installation Guide
Safety extra low voltage
Earthing
Interruption of the power supply
Warning
HiPath Wireless Outdoor APs are designed for operation with a directly connectable safety extra-
low voltage or with the power supply adapters available as accessories (available only for HiPath
Wireless Outdoor AP devices). Therefore, only safety extra-low voltage (SELV) with limited
power source (LPS) complying with IEC950/EN60950/VDE0805 may be connected to the power
supply terminals (exception: Power supply adapter for 110 - 230 V AC for the HiPath Wireless
Outdoor AP).
The power supply unit to supply the HiPath Wireless Outdoor AP must comply with NEC Class
2 (requirements of class 2 for power supply units of the "National Electrical Code, table 11 (b)")
or SELV with LPS (Limited Power Source) EN 60950-1. If the power supply is designed
redundantly (two separate power supplies), both power supplies must meet these requirements.
Exception:
•
Power supply with PELV (according to VDE 0100-410 or IEC 60364-4-41) is also possible if
the generated rated voltage does not exceed the voltage limits 25 V AC or 60 V DC.
Caution
There must be no potential difference between the following parts, otherwise there is a risk that the device
will be destroyed:
• Ground potential of the power supply and ground potential of the antenna ground.
• Ground potential of the power supply and a grounded housing.
• Ground potential of the power supply and the ground potential of the device connected to Industrial
Ethernet (for example PC, AS-300, AS-400 etc.)
Connect both grounds to the same foundation earth or use an equipotential bonding cable.
Caution
Damage to the Ethernet interface
Repeated fast removal and insertion of the Ethernet cable when using Power-over-Ethernet and when there
is a redundant power supply can cause damage to the Ethernet interface.
Avoid repeatedly removing and inserting the Ethernet cable when using Power-over-Ethernet and a
redundant power supply.
