Appendix A: Safety and Regulatory Compliance Information for the MX104 Router
Ensure that the polarity of the DC input wiring is correct. Under certain conditions,
connections with reversed polarity might trip the primary circuit breaker or damage
the equipment.
For personal safety, connect the green and yellow wire to safety (earth) ground at both
the router and the supply side of the DC wiring.
The marked input voltage for a DC-powered router is the nominal voltage associated
with the battery circuit, and any higher voltages are only to be associated with float
voltages for the charging function.
Because the router is a positive ground system, you must connect the positive lead to
the terminal labeled , the negative lead to the terminal labeled
+
to the chassis grounding points.
