9. Instructions before
switching on
Before using the unit with all the necessary safety,
the user must read carefully chapter 2 which deals
with safety provisions.
10. Connection to the line
The electrical installation including the unit must
always be connected through a safety device (fuse,
circuit breaker) to a disconnecting device which
isolates the whole set of power wires.
These equipments must be in accordance with the
standards. They must provide a breaking capacity
compatible with currents and voltages peculiar to
the equipment. They must be placed close to the
unit and well-recognized using an adequate
marking. For parallel connection, follow the rules
concerning the circuit setting.
