Cat. No(s): 4 141 55/56/85/86
4. POSITIONING, CONNECTION (continued)
4.7 Replacing plug-in modules
Recommendation:
The installation must not be switched back on (DC/AC) without the
plug-in modules fitted.
4.8 Status feedback
A signalling accessory is included for feedback of the SPD status.
5. GENERAL CHARACTERISTICS
Marking on the front (plug-in modules)
. By indelible pad printing
Marking on the front (base) and markings on the side (base and
plug-in modules)
. By laser

(2)
Maximum current that the PV SPD can withstand in the event of end
of life due to a short-circuit without adding any external protection,
irrespective of the local environmental, temperature, sunlight conditions,
etc. This value must always be greater than the max. short-circuit current of
the PV generator (1.25 Iscstc).
