Description

This is a Siemens 6GK5774-1FY00-0TB0 SCALANCE W774-1 M12 EEC, an Industrial Wireless LAN (IWLAN) access point designed for reliable communication in demanding environments. The unit features a single radio interface supporting IEEE 802.11a/b/g/h/n standards across both 2.4 GHz and 5 GHz frequency bands, delivering a gross data rate of up to 300 Mbit/s. It includes an integrated 2-port switch with rugged M12 connectors and supports Power over Ethernet (PoE) for simplified installation. Power can also be supplied via a redundant 24 V DC input. With a conformal coating, an IP30 rating, and compliance with EN 50155, this device is engineered for transportation systems and other harsh industrial settings.

Installation Guidelines

1. 1 Verify package contents. Ensure the SCALANCE module, M12 sealing caps, and documentation are present before beginning installation.
2. 2 Mount the access point securely to a stable surface or DIN rail within the control panel or enclosure. Ensure adequate clearance for cable routing and heat dissipation.
3. 3 Connect the R-SMA antennas to the designated ports. Tighten connections to be finger-tight plus a quarter turn with an appropriate tool to ensure a secure RF link. Do not overtighten.
4. 4 Terminate the M12 Ethernet cables for network connectivity. If using PoE, confirm the upstream switch or injector meets the device's power requirements.
5. 5 If using a local power source, connect the redundant 24 V DC supply via the specified M12 A-coded connector, observing correct polarity.
6. 6 Ensure the unit is properly grounded according to site and regulatory requirements to minimize the effects of electrical noise and ensure safety.
7. 7 After all physical connections are secured and verified, re-apply power to the system and proceed with software configuration of the access point.
