Notes on Lightning Protection
A suitable lightning conductor is available to order for the WS-AP3765 and WS-AP3767e:
Lightning Protector part number: WS-CAB-LPM
Safety Extra-Low Voltage
Grounding
3-2 Connecting Cables to the Outdoor Access Points
Warning: Antennas installed outdoors must be within the area covered by a lightning protection
system. Make sure that all conducting systems entering from outdoors can be protected by a
lightning protection potential equalization system.When implementing your lightning protection
concept, make sure you adhere to the VDE 0182 or IEC 62305 standard.
Warning: Installing this lightning protector between an antenna and an WS-AP3765 or
WS-AP3767e is not adequate protection against a lightning strike. The lightning protector
only works within the framework of a comprehensive lightning protection concept. If you
have questions, consult a qualified specialist company.
Note: The requirements of EN61000-4-5, surge immunity tests on power supply lines, are met only
when a Blitzductor is used with 12V DC to 24V DC:
• 12V DC: VT AD 24V type no. 918 402
Manufacturer: DEHN+SÖHNE GmbH+Co.KG Hans Dehn Str.1 Postfach 1640 D 92306 Neumarkt,
Germany.
Warning: The WS-AP3765 and WS-AP3767e access points are designed for operation with a
directly connectable safety extra-low voltage or with the power supply adapters available as
accessories (available only for WS-AP3765 and WS-AP3767e 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 100 - 240 V AC for the WS-AP3765 and WS-AP3767e).
The power supply unit to supply the WS-AP3765 and WS-AP3767e 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 25V AC or 60V DC.
Caution: There must be no potential difference between the following parts, otherwise there is a
risk that the device will be destroyed:
• Housing of the WS-AP3765 or WS-AP3767e and the ground potential of the antenna.
• Housing of the WS-AP3765 or WS-AP3767e and the ground potential of a device connected
over Ethernet.
• Housing of the WS-AP3765 or WS-AP3767e and the shield contact of the connected Ethernet
cable.Connect both grounds to the same foundation earth or use an equipotential bonding cable.
Warning: DO NOT DISCONNECT EQUIPMENT WHEN A FLAMMABLE OR COMBUSTIBLE
ATMOSPHERE IS PRESENT.
Warning: EXPLOSION HAZARD – SUBSTITUTION OF COMPONENTS MAY IMPAIR
SUITABILITY FOR CLASS I, DIVISION 2 OR ZONE 2.
