36 SMART-MR10/15 User Manual Rev 5
Chapter 2 Installation
2.3.1 Connecting the Power Supply
The SMART-MR10/15 requires +9 to +36 VDC for the input power to the receiver. See Appendix A.2
starting on page 75 for SMART-MR10 power supply specifications, and Appendix A.3 starting on
page 79 for SMART-MR15 power supply specifications.
The SMART-MR10/15 cable provides power in (with a BATT+ label) and power ground (with a
BATT- label) bare wires for connections from the SMART-MR10/15 to a vehicular power system
protected by a user-supplied fuse. NovAtel recommends an automotive blade-type fuse, rated for 5A
with an operating voltage of more than 36V. For cable details, refer to Appendix A.4.3, Custom
Connector and Cable Requirements starting on page 87.
Once you apply power, the SMART-MR10/15 status lights will light as described in Status Indicators
starting on page 37.
Fuse/holder recommendations can be found in Table 14, Recommended Fuses on
page 87.
The SMART-MR10/15 power source must be protected by a 5A fuse or damage to
wiring may result (not covered by warranty). If the voltage supplied is above or
below the specified range, the receiver will suspend operation. If the voltage
supplied is above 48V, the receiver may be permanently damaged, voiding your
warranty.
