Terminals 17 and 18 and terminals 19 and 20 must be shorted
externally

+24 VDC POWER OUT (1 A max)
Power output signal (+), must be connected to terminal 5 on the
M module

-24 VDC POWER OUT (1 A max)
Power output signal (-), must be connected to terminal 6 on the
M module
Notes:
24V IN and 24V OUT are not galvanically separated.
The two-color LED indicates the module operating status and battery status:
short pulses in green colour (0.5 s on / 1.5 s off):
pre-charging (battery discharged),
pulses in green colour (0.5 s on / 0.5 s off):
main charging,
long pulses in green colour (1.5 s on / 0.5 s off):
recharging (battery charged),
green color of the diode (continuous signal):
the battery is fully charged (supplying the device from a battery),
pulses in red colour (0.5 s on / 0.5 s off):
battery heavily discharged (supplying the device from a battery),
red color of the diode (continuous signal):
failure state, e.g. failure of temperature sensor or battery, temperature exceeding.
If the PSBATT module is installed, it is forbidden to connect the power supply to the M
module (terminals 5, 6, 7). The power supply must be connected only to the PSBATT module
(24V IN).
The power supply output signal must be connected from the PSBATT (24V OUT)
module to terminals 5, 6 on the M module.
Terminal 7 on the M module should be connected
to GND or PE. Use only dedicated power supply.
The double external switch is used to power the device, it does not disconnect battery
charging.
From April 1, 2020, the PSBATT module is manufactured only in version 1.2. Version
1.2 of the module is not backward compatible. The presented way of connecting signals
applies only to version 1.2 of the module. To connect signals to module in version 1.0 or in
version 1.1, contact the Manufacturer.
