1)
For high-tolerance electromagnetic compatibility (EMC) in 115/230 V units,
the screw connection for the protected earth terminal (page 30, pos. 7) to
ground must be additionally provided.
This connection must also be low-impedance for high frequencies (copper
rod or HF litz wire). Otherwise a 2,5
V
litz wire should be used.
Connected to the mains power supply via a 2-pole switch
in the accessible region (fire protection according to IEC
66E (sec) 22/DIN VDE 0411 part 100). For circuits
without limitations, the power supply to the device must
be provided via a switch. For circuits with limitations
(
≤
30 Vrms or
≤
42.4 V DC and current
≤
8 A or source
under all loading conditions
≤
150 VA or fuse link
corresponding to
≤
150 VA ) a switch is not required.
If the 24 V UC power supply unit is secured with
≤
4 A
(35 V DC) (T 3.15 A as a min. requirement) the switch is
not required.
