1. Read and follow all warning notices and instructions marked on the product or
included in the manual.
2. All installation and service must be performed by qualified service personnel, as
opening or removing covers may expose dangerous voltage points or other risks.
3. This product is intended to be used in a restricted access location. Connect the
product to a – 48 VDC SELV (Safety Extra Low Voltage) supply source that is

earthing (grounding) lug connector, identified by the protective earth symbol. This
is a safety feature. 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. If the wiring is not properly grounded, the installation must not
continue until a qualified electrician has corrected the problem.
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.
Overcurrent protection must be a 15 or 20A, – 48 VDC fuse or circuit breaker.
