Table 7: Types of Alarm
Always switch off the mains power supply before working on the electrical or mechanical part of the system. Wait for the warning lights on the control panel to go out before opening the appliance. The capacitor of the direct current intermediate circuit remains charged with dangerously high voltage even after the mains power has been turned off.
Only firmly cabled mains connections are admissible. The appliance must be earthed (IEC 536 class 1,
NEC and other applicable standards).
Ensure that the voltage and frequency on the data plate of the EVOSTA2 SOL circulator are the same as those of the power mains.
