Connecting the device to the external power supply
Regulated power supply, with output voltage from12 to 24 V and allowable load current no less than 250 mА for 12 V and no
less than 125 mА for 24 V, is connected to
12-24 V
socket (figure 3 , position
19
) on the device case. If the external power
supply is used, batteries supply will be automatically disabled.
Figure 5 – Socket for external power supply
You should use lithium batteries as an independent power supply.
Do not mix batteries of different types or from different manufacturers in one set.
To prevent the breakdown of the device, the socket (figure
5
) of the direct current regulated source must have positive
potential on its central pin.
Use of third-party power source can damage the device. We recommend using the equipment from the delivery set.
The manufacturer is not responsible for device functioning when it is connected to third-party power source.
