1. Indoor Units. Power lines and signal cable (min. section of 1.5mm
2
for all Models), prewired-up on
each Indoor Unit and provided of plug, must pass from Indoor Unit to Outdoor Unit, by starting from Indoor
Unit’s back and getting to specific connector (Unit “A”, “B”, “C”, “D”) on Outdoor Unit. If it is needed to
increase wiring standard length (6 metres), always use cables in accordance with to law only.
2. Terminal block can be reached by removing electric box’s protection cover, on Indoor Unit’s right side.
3. Always fix cables on screw terminal blocks firmly, and always use the special wire clamps on Indoor
Units to avoid that any traction on cables may be sent to terminal blocks’ contacts.
4. If protection fuse is broken, replace it by a fuse which is equivalent to original one.
5. Outdoor Unit. Power supply line must be for system only, that is it must not be shared with other
appliances. A circuit breaker must be installed - with suitable calibration to the system’s power input -
which simultaneously interrupts all contacts; in opening position, min. distance between contacts must
be of 3 mm. Moreover, the installation of an earth breaker is required, specific for Inverter appliances.
