Safety class I with parts according to II and III to
DIN EN 60730-1
IP00
Degree of protection
Note:
The burner or boiler
manufacturer must ensure
degree of protection IP40 for
burner controls as per DIN EN
60529 through adequate
installation of the LME7...

Weight Approx. 490 g
4.2 Terminal rating Inputs
Mains voltage: Input current depending on the operating state of the unit
Under voltage U
Mains 120 V UMains 230 V
Safety shutdown from the operating
position takes place should mains
voltage drop
≤AC 75 V ≤AC 165 V
Restart is initiated when mains
voltage exceeds
≥AC 100 V ≥AC 195 V
State inputs, temperature controller, temperature switch, load controller, pressure
switch, air pressure switch, actuator (except safety loop) of the contact feedback
network (CFN) are used for system supervision and require mains-related input
voltage
Input safety loop See Terminal rating outputs
