1.4 Safety instructions
Writing conventions
Warning!
WARNING!
• Avoid the described hazard: Otherwise there is danger from electric voltage that can lead to
death or serious bodily injury.
Caution!
CAUTION!
• Avoid the described hazard: Otherwise minor or medium bodily injury or property damage will
result.
For your safety
For safe operation and to avoid personal injury and equipment damage through operating error, al-
ways read these instructions, become familiar with the device, and follow all safety instructions on the
product and in this document, as well as the safety guidelines of Wurm GmbH & Co. KG Elektronische
Systeme. Keep these instructions ready to hand for quick reference and pass them on with the device
if the product is sold. Wurm GmbH & Co. KG Elektronische Systeme accepts no liability in case of
improper use or use for other than the intended purpose.
Warning!
WARNING! DANGER TO LIFE FROM ELECTRIC SHOCK AND/OR FIRE!
• Switch off the power to the entire system when installing, wiring or removing! Otherwise a mains
voltage and/or external voltage may still be present even if the control voltage is switched off!
• The wiring of the device should be carried out only by a qualified electrician!
• Use only the correct tools for all work!
• Check all wiring after connection!
• Take note of the maximum loads on all connections!
• Never expose the device to moisture, for example due to condensation or cleaning agents!
• Take the device out of operation if it is faulty or damaged and is therefore compromising safe
operation!
• Do not open the device!
• Do not repair the device yourself! If required, send it in for repair with an exact description of the
fault!
• Do not use the device in locations where there may be children!
Target group These instructions are intended for "service technician" personnel.
Intended use
GTW-LAN 2.1 is used for remote data transmission over a network. It
automatically forwards alarms to up to 5 different destinations per sub-
section.

1.5 Installing the device
The device is intended for top-hat rail installation and is suitable for operation in fuse boxes and dis-
tribution cabinets. The devices can be positioned immediately next to another without gaps.
Warning!
WARNING! DANGER TO LIFE FROM ELECTRIC SHOCK AND/OR FIRE!
• Switch off the power to the entire system before installing! Otherwise a mains voltage and/or
external voltage may still be present even if the control voltage is switched off!
• Take note of the maximum loads on all connections!
The entire system must be free of voltage.
1. (A) Place the device with the leading edge at an acute angle to the top-hat rail.
2. (B) Push the device downwards onto the the top-hat rail.
The device snaps into the top-hat rail with fastening catch (a).
You can now connect the device.
