Hazardous Location Requirements
The enclosure of the power supply and the MPM will need to be grounded to earth ground
according to local building codes for hazardous location use. The back side of the power
supply is bare metal, allowing it to be grounded to the mounting plate when it is bolted in
place. The mounting plate will need to have no coating where the power supply is installed
in order to provide electrical conductivity.
