ELECTRICAL CONNECTIONS
IMPORTANT WARNINGs: ELECTRICAL HAZARD
For protection against electric shock, connectors must be isolated from the power supply
while being assembled or disassembled.
Never perform electrical connections when the CCBu40 is powered-on. The CCBu40
provides high voltage outputs to the piezo actuators (>100V), and there is a risk of
electrical shock. If the board has been powered-on before, wait at least 1min after power-
off before working on the electrical connections.
Each time the connectors are used, it should previously be inspected for external defects
(particularly in the insulation). If there are any doubts as to its safety, a specialist must be
consulted, or the connector must be replaced.
