12 | Operating Manual GW 601 | Assembly and installation
ATTENTION!
The assembly location must be selected so that the device is not subject to any mechanical load or chemi-
cal exposure in any way.
When assembling make sure there is clear access to the device.
6.2 Transmitter
• A transmitter can be connected to the GW 601 gas warning device.
• The transmitter is connected via a shielded 3-wire cable.
• All input and output wires and cables must be shielded. The shielding must be applied on one side
only.
• The gas inlet of the sensor must be kept clear of dust and contamination.
• Wall assembly is with the sensor opening facing down, close to the ground (approx. 30 cm high) with
two screws (max. Ø 4 mm) and only with the cover open.
• During assembly make sure that the transmitter is accessible for maintenance work.
• Keep a minimum distance of 10 cm between the sensor opening and other fixtures.
The cables pass through the PG connections into the housing interior. The cable entry point consists of the
flange which screws into and is sealed in the basic housing, the clamp/seal assembly and the threaded
sleeve. Insert the cable in turn through the threaded sleeve, clamp/seal assembly and the flange. Make sure
the clamp/seal assembly is correctly installed. Fasten the cable by screwing the threaded sleeve tightly.
Note
The cable shielding must not be introduced into the transmitter. The grounding terminal in the housing
should not be occupied.
All transmitter terminals are plug-in terminals. Remove the connectors before routing the cables to avoid
mechanical damage. Do not plug them back in until you have completed the assembly.
