Installation and operating instructions, ATS022
(1
On 1 phase system is not allowed to choose 100 V, 115 V and 120 V.
(2
If voltage level is between 57,7 – 109 Vac, AUX power supply must be used.
(3
In system with rated frequency is 16 2/3 an AUX voltage have to be used; if rated voltage is higher than 100Vac
external voltage transformer must be used.
(4
Whenever ATS022 is used at low temperatures (lower than -10°C) it is advisable to use an external voltage to avoid
any visualization problems on the graphical display.
