PELV or SELV
The current for the powerpack must be limited to
a maximum of 4 A – either by the powerpack it-
self or by a fuse
UL 508: Use a galvanically isolated power supply
with limited output voltage and power (42.4 VDC,
100 VA). The output voltage must be secured by
a fuse that meets the standards according to UL
248. Connect all supply connections of the sys-
tem to a common source and ensure a common
ground connection when using several sources.
Max. 3.3 W
4 A gG (with tripping characteristic B or C)
24 V DC (16.8 to 30 V DC)
PELV or SELV
The current for the powerpack must be limited ex-
ternally to a maximum of 8 A per output group
(B1 and B2) – either by the powerpack itself or by
a fuse.
