Installation

Grounding

The equipment must be grounded to reduce the risk of static sparking and electric shock. Electric or static sparking can cause fumes to ignite or explode. Improper grounding can cause electric shock. Grounding provides an escape wire for the electric current.

The DCM and ADCM are used in a variety of systems, with varying grounding requirements.

Follow all instructions in your system manual.
