Attention! Connecting the device to the COM port of the computer when the
power of the device is turned on can damage the RS-232 interface of the device's
processor.
Connect the power supply:
−
from the AC power line (100 - 240) V, 50 or 60 Hz to socket "220 V, 50
Hz, 40 V·A"
−
from the DC power supply: (22 – 30) V to "
22…30 V" (backup power
source).
Make sure that the "POWER", "NORM" and "
22 ... 30 V 35 W" indicators on
the power module panel are lit.
The "
22 ... 30 V" indicator on the power unit panel lights up only if there is a
DC voltage on the "
22 ... 30 V 35 W" connector.
To connect an external power source use a power cable with a
2PMT14КПН4Г1В1 (2PM14-4TKQB2) type connector. Pin 1 of the connector must
be connected to the positive pole of the DC power supply, and pin 4 to the negative
pole of the power supply (see Figure 4).
