All Installation and service must be performed by qualified service personnel.
Read and follow all warning notices and instructions marked on the product or included in the manual.
Required Grounding
This product is intended to be used in a restricted access location Connect the device to a 48 VDC SELV (Safety Extra Low Voltage) supply that is electrically isolated from the DC Source. The 48 VDC source is to be reliably connected to earth (ground). Equipment grounding is vital to ensure safe operation.
Prior to installation, use a voltmeter/ohmmeter to check the wiring for the presence of earth ground.
Required Disconnect
A readily accessible disconnect device as part of the building installation shall be incorporated into the fixed wiring. The disconnect device (a 48 VDC, 15 or 20A circuit breaker or switch) must be included in the ungrounded supply conductor.
