5 Connection 5.1 Lightning protection, power supply and grounding Lightning protection WARNING Danger due to lightning strikes 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.
Connection 5.1 Lightning protection, power supply and grounding Note We recommend that you use the maintenance-free lightning protector LP798-2N. Exception: When there is also DC power supplied via the antenna cable. In this case, only the lightning protector LP798-1N can be used. WARNING Danger due to lightning strikes Installing this lightning protector between an antenna and a SCALANCE W700 is not adequate protection against a lightning strike.
Connection 5.1 Lightning protection, power supply and grounding Grounding WARNING Danger to life from overvoltage, fire hazard When using outdoor antennas, the shared or even grounded pin of the circuit must be connected to the shield of the coaxial cable and with all touchable conductive parts and circuits. Otherwise, in the event of a fault there may be illegally high voltages on touchable parts.
Connection 5.1 Lightning protection, power supply and grounding General notes on use in hazardous areas according to UL-HazLoc WARNING EXPLOSION HAZARD DO NOT DISCONNECT WHILE CIRCUIT IS LIVE UNLESS AREA IS KNOWN TO BE NON-HAZARDOUS. This equipment is suitable for use in Class I, Division 2, Groups A, B, C and D or nonhazardous locations only. This equipment is suitable for use in Class I, Zone 2, Group IIC or non-hazardous locations only.
Connection 5.2 Power supply 5.2 Power supply Note Galvanic isolation of the power supply unit To ensure dielectric strength according to IEEE 802.3, the supplying 24 V power supply unit must be galvanically isolated with a dielectric strength of 1500 VAC. The galvanic isolation must also not be bridged by other devices connected to the same power supply unit.
Connection 5.2 Power supply SCALANCE W774 M12 EEC For the power supply, there are two options with the SCALANCE W774 M12 EEC: ● Direct feed in via the four-pin M12 socket (position ①) ● Power over Ethernet via the M12 Ethernet interface P2 (position ②). The other Ethernet interface P1 is not capable of PoE.
Connection 5.2 Power supply The SCALANCE W774/W734 RJ-45 devices support the standards IEEE 802.3at type 1 (IEEE 802.3af ) and IEEE 802.3.at type 2. Note Disabling the PoE power supply Before you pull a plug via which the device is supplied with power using PoE, disable the relevant PoE power supply. Note "Phantom power" only with SCALANCE W774 M12 EEC The SCALANCE W774 M12 EEC device only supports the standard IEEE 802.3 at type 2.
Connection 5.3 Ethernet 5.3 Ethernet The SCALANCE W774/W734 devices have two Ethernet interfaces located on the underside of the device. Depending on the version, either RJ-45 or M12 sockets are available. SCALANCE W774/W734 RJ-45 ① ② Ethernet interface P1 Ethernet interface P2 The power can also be supplied via this interface (Power over Ethernet).
