Power Supply Requirements
Rated Operating Voltage: 10...30 Vdc
Nominal Operating Voltage: 12 Vdc and 24 Vdc
Input Power (Rx typical): 5 W
Input Power (Tx typical): (See table below)
Typical receive/standby input power is 5 Watts. The input power will vary in transmit
mode according to RF output power level.
The QR is supplied with a lock-in mating DC power connector (Schneider Electric
Part Number TBUMPWR-PLUG-QR-A) which should be installed with the locking
screws done up tightly (0.5 - 0.6 Nm / 4.42 - 5.31 ftin).
The radio is designed to limit damage if the voltage exceeds 30 Vdc or if reverse
polarity is applied. The field-replaceable internal fuse has a 7 Amp rating. Fuse replacement instructions can be found within this
user manual. Fuses are available from Schnedier Electric, part number TBUMPWR-FUSE-QR.

Connect and secure the antenna, Ethernet and serial connectors BEFORE applying power to the unit. Lastly, before inserting
the power connector, re-check that the polarity and voltage is correct using a multimeter and check the power cable against
the +/- label printed on the front panel of the radio.
NOTICE
HAZARD OF EQUIPMENT DAMAGE
The radio modem can be damaged if there is any potential difference between
the chassis-ground, RS232 signal ground, power (-) input, or antenna coaxial
shield. Before connecting any wiring, ensure that all components are earthed to a
common ground point.
Failure to follow these instructions can result in equipment damage.
