Electrical connections
A switch or an omnipolar cut-off switch with a contact opening of at least 3 mm must be installed on the mains power
line; put the cut-off switch in OFF position and disconnect any buffer batteries before performing any cleaning or
maintenance operations.
Ensure that an adequate residual current circuit breaker with a 0.03 A threshold and a suitable overcurrent cut-out
are installed upstream the electrical installation in accordance with best practices and in compliance with applicable
legislation.
For power supply, use a H07RN-F 3G1.5 type electric cable and connect it to the terminals L (brown), N (blue),
(yellow/green), located inside the control panel box.
and secure the cable with the cable retainer.
Measure the voltage on the primary mains power connection with a tester.
TRANSFORMER
For the Brushless automation system to function correctly, the mains power voltage must be:
- 230V~ ±10% for the B70/1THP control unit.
- 115V~ ±10% for the B70/1THP/115 control unit.

Connections to the electrical distribution network and to any other low-voltage conductors in the external
section to the electrical panel must be on an independent path and separate from the connections to the
command and safety devices (SELV = Safety Extra Low Voltage).
Make sure that the mains power conductors and the accessory wires (24 V) are separated.
The cables must be double insulated, strip them near the relevant connection terminals and lock them with clamps
(not supplied).
