General installation instructions
The TOWERCHRON QM1 and QM2 are both 
double insulated so earth protection is not 
required� However in the backplate a terminal for 
earth continuity is provided which should be used 
if earth conductors are present in your cable� 
Make sure that the earth conductors are sleeved 
to prevent accidental contact with live parts�
