DIN Track Insulation
Spacers
Noise can interfere with proper operation if the ground wire connected to the
PC is shared with other equipment. If the CQM1H is mounted to DIN Track,
electrical continuity will be created with the control panel. To insulate the
CQM1H from the control panel, use DIN Track Insulation Spacers.
