F ELECTRICAL CONNECTIONS
The box receives several cables, i.e. the grey cable which connects the foot-control cable to the box, the black four-wire
cable for serial connection with the dental unit, and the white three-wire cable (brown, blue, and yellow/green) for chair
mains supply.
The following ones are coming from the dental unit:
one three-wire (blue, brown, yellow-green) black cable, one three-wire (blue, brown, yellow-green) white cable, one
more white (two-wire) and one more black one (two-wire), a grey cable for dental unit connection to foot-control
extension, a four-wire black cable for serial connection to the chair, and one more black cable ending by two faston
connections.
The safety connectors (a black and a white one) have ten terminals.
