- Protection of power feed (must be ordered):
- Power pack A:
ABB Stotz m.c.b.: S 282 UC-K, 1.6 A
- Power pack B:
ABB Stotz m.c.b.: S 282 UC-K, 1.0 A
- Power consumption on the input side during a charging
process: ca. 100 W
- Power consumption in normal position: P < 10 W
- Charging times of the capacitor (example for DC voltage):
a) Initial charging on commissioning:
- Breakers to 25 kA:
- Breakers from 31.5 kA:
depending on the supply voltage.
In this time, the capacitor(s) is/are charged to 80 V, and
an ON-OFF operating cycle is already possible at 72 V.
(The "READY" lamp indicates readiness for switching.
A flashing "READY" lamp signals recharging of the ca-
pacitor. Switching readiness is enabled during that time).
b) Recharging after a switching operation to a charge of
80 V: max. 5s.
Different response ranges for individual inputs on request.

2)
In general, with AC signals which are connected via long lines, it should be checked
3)
whether the installed base load of 300 kΩ is sufficient (mutual capacitive coupling!)
to ensure a reliably low interference level. Otherwise, an appropriately dimensioned
resistor or capacitor is to be connected in parallel at the input terminals.
