Powering the Receiver

1.4.2. Powering the Receiver
Power supply requirements
The socket-outlet shall be installed near the equipment and shall be easily accessible.
A single external power supply with 5 pin ODU connector or SAE connector is necessary to operate
DELTA. If external power supply has only SAE connector, Receiver-to-SAE power cable shall be used.
The external power supply needs to be Listed for US and Certified for EU countries, it needs also to be a
Limited Power Source and have an output rated for 4,5...35 V DC, not less than 2A. This may not be the
same range as other JAVAD GNSS products with which you are familiar.
C : To avoid the introduction of hazards when operating and installing, before connecting of the equip-
AUTION
ment to the supply, make sure that the supply meets local and national safety ordinances and
matches the equipment's voltage and current requirements.
C : Never attempt any maintenance or cleaning of the supply while plugged in. Always remove supply
AUTION
from AC power before attempting service or cleaning.
Warning: If the voltage supplied is below the minimum specification, the receiver will suspend operation. If the voltage
supplied is above the maximum specification, the receiver may be permanently damaged, voiding your
warranty.
Make sure cords are located so that will not be stepped on, tripped over, or otherwise subjected to
damage or stress. Do not operate equipment with a damaged cord or plug – replace immediately.
To reduce the risk of damage to the equipment, pull by the plug body rather than the output cord
when disconnecting the equipment.
Do not operate the supply if it has received a sharp blow, been dropped, or otherwise damaged. Do
not disassemble the supply.
Warning: Before connecting the external power source and the receiver, make sure that the power source matches the
receiver's voltage and current requirements.

1.4.3. Turning On/Off the Receiver

To turn ON the receiver, press and hold the power button until the LEDs briefly flash. To turn OFF the
receiver, press and hold the power button for more than one and less than four seconds (until both the SAT
and the REC LEDs are off). This delay (about 1 second) will prevent the receiver from being turned off
by mistake.
Delta saves the last power status and restore it after voltage loss.
