sation when PDS is out of service.
Site altitude – –
Max. 2000 m above sea level
• With site altitudes over 1000 m a derating
of 1 % per 100 m must be taken into con -
sideration.
• With site altitudes over 2000 m, the control
board to the mains has only basic isola-
tion. Additional measures must be taken
when wiring the control.
