5.3 Connecting the level switch
The GL 3 provides the option to install a model NS1/GL45 level
switch. The receptacle therefore has a GL45 connection.
DANGER
Explosion hazard
To use the GL 3 in an explosive atmosphere with level switch,
the level switch and controller must be ignition protection
class intrinsically safe "i". The use of non-intrinsically safe
components may result in ignition in explosive atmospheres.
Also note the specifications under EN 60079-14 in this respect.
The level switch must be screwed in tight, sealed with Teflon
tape or sealant/flat gasket!
Pay attention to leaks!
Please be sure to run the connection cable safely and without
tension. If possible, the cable between the level switch and
controller should NOT be run inside conduit with switch
cables, as these may cause interference.
Please refer to the separate operating and installation instruc-
tions included with the product for addition information on
connecting the level switch and controller.
