5.4.4 Mains and Batteries connection
The connection to the 230 V AC power supply mains must be performed through three-conductor cable
(phase- neutral- earth).
The identification of the earth conductor coming from the mains must be performed on the CN1 terminal block
(refer to basic board topography) and must be fixed at the heart bar by means of cable –tightening strip so that
it cannot be accidentally stripped off from the terminal block.
The 230 V AC power supply cable must be fixed inside the control unit by means of an appropriate cable fixing
device.
The cable fixing collars must be HB flammability class.
The mains supply conductors shall not be consolidated by means of a soft welding.
A sectioning device external to the control unit must be provided for the 230 V AC power cable
(contact separation: min. 3 mm) The sectioning device must be omni-polar or must disconnect the line phase
Power Supply connection must be done following this procedure: (Refer to Base Board)
1. Turn off the main power switch of the 230 V AC mains.
2. Disconnect the CN1 terminal block from the control unit.
3. Connect the mains cable.
4. Re-connect the CN1 terminal block.
5. Turn on the mains switch.
6. Install and connect the batteries as indicated in this manual.
Once the control unit has been powered, it will automatically start operating.
However, in accordance with the battery storage period, it is necessary to wait some hours before the
batteries are completely re-charged.
7. Check the operation of the LED indicators on the panel, according to the paragraph
“TEST AND STARTING OPERATION”.
8. Close the control unit.
