Page 7: Installation And Connection
5 INSTALLATION AND CONNECTION The RCBO shall be installed and connected by qualified electrical per- sonnel. Before installation, make sure that: • The device characteristics (RCBO marking) meet the required values. • The device has no visible damage. • The mechanism properly operates (by turning the handle a few times and pressing the «T»... -
Page 8: Operation Conditions
After the RCBO trips by residual current (the operating handle turns to the OFF position and the button next to the handle is released), carefully in- spect the insulation of wires and devices in the protected circuit and trou- bleshoot the causes of current leakage. Press the button indicating the device trip and turn the operating handle to the ON position to reclose the device. -
