(*) Note: for lengths exceeding 50 m and up to 200 m, the connection
between KTAU and circuit board of the Chiller/heat pump, must be
realised using an AWG 20/22 shielded cabl e (4 wires + screen) and
two by-pass boards (use the E968573484 Kit) as in the layout shown
below.

The connections between board and switc h or remote light must be
made with screened cable (make sure the screening is continuous
throughout the length of the c able) c onsisting of 2 twisted 0.5 mm² wires
and the screening. The screening must be connec ted to the earth scr ew
on the panel (on one side onl y). T he maxi mum permitted distanc e is 30
m.
Lay the c abl es far from power cables, c ables with a different voltage
and cabl es that emit elec tromagnetic distur banc e.
Do not lay the cabl es in the vicinity of appliances that could create
electromagnetic interferenc e.
