2.3 CONNECTING THE CONTROL UNIT
The installation and the electrical connections must be carried out by qualified personnel in accordance
with the instructions set out in this manual and on the diagram shown on the back of the cover of the
U•H1 control unit.
It is recommended to place the circuit breaker in the vicinity of the equipment.
All installations must comply with locally-applicable standards and regulations, notably the cable type
and section of the wires to be used.
During electrical connection of the terminals, make sure the wires are attached to the connectors. Use
a maximum tightening torque of 0.60 Nm. In order to achieve electrical safety, wires going from the
enclosure’s cable glands to the board’s terminal blocks shall not be longer than 70 mm.
It is recommended to always use wires with a crimping end to avoid any risk of poor electrical contact.
Example of a connection diagram for the
U•H1 control unit:
A circuit breaker (2-poles, 6A, 250V (AC)) must be placed on both live and
neutral. See the wiring example below.
