Fig. 4. Connection of cameras and network devices to the LAN and POE terminals.
5. Check the power supply output voltage:
- output voltage of the unloaded power supply without a battery should amount to U=54V DC.
6. Connect the batteries in series according to the color markings:
- battery output (+V): BAT+ cable/ red
- battery output (0V): BAT- cable / black
7. Check the optical indication of the PSU status.
8. Close the cover after installing and checking the operation of the power supply.
3. Power supply operation indication.
The presence of voltage at the input of PoE modules is indicated by LEDs on the front panel.
4. Service and operation.
4.1. Overload or short-circuit of the power supply output.
In case of overload, the output voltage is automatically shut off, and so is the LED indicator. The
restoration of the voltage takes place immediately after the failure (overload) is over.
4.2. Battery operation
In case of mains power loss, the unit will instantly switch to battery operation.
The power supply is equipped with a discharged battery disconnection system. If
the battery voltage has dropped below 38V during the battery operation, the battery will be
disconnected.
4.3. Maintenance.
All maintenance procedures can be performed after disconnecting the power supply from the power
network. The PSU does not require any specific maintenance; however, its interior should be cleaned with
compressed air if used in dusty conditions. The battery status should be checked periodically. (battery capacity
loss, too high internal resistance) batteries should be replaced. In case of fuse replacement, use only compatible
replacement parts.
