13.5 Application limits
B2F020 as ”Standard power supply”
z As basic emergency power supply.
Maximum load:
1 x E3X10. with max. 2 x 12 V, 42 Ah batteries and 1 x E3C... with max. 2 x 12 V,
42 Ah batteries (E3X10. incl. lines- / control modules, AlgoPilot B3Q... control con-
sole etc.)
B2F020 as ”Auxiliary power supply”
z In parallel operation with the standard power supply.
E.g. if long duration of emergency operation is required.
Maximum load:
3 x E3C... each with 2 x 12 V, 42 Ah batteries
Note
– B2F020, E3X10. and all E3C... must be installed in the same housing (or in hou-
sings mounted solidly together)
– The required emergency power supply battery capacity (number of batteries)
must be calculated based on the individual quiescent current (see document
1076 / EP5, 008725 / EP7F-Z1 ”Calculating emergency power supply”)
– Batteries larger than 42 Ah per E3X10. or E3C... are impossible if the recharging
of a battery is to be done according to regulations (to 80 % capacity within 24 h)
