UB20.241
U–Series
24V, 20A, DC-UPS
21. DIELECTRIC STRENGTH
The relay contacts and the inhibit input are floating and separated from the input and output voltage. The following
isolation tests were performed.

Type tests and factory tests:
Conducted by the manufacturer. Do not repeat test in field!
Rules for field test:
Use appropriate test equipment which applies the voltage with
a slow ramp (2s up and 2s down). Connect input and output
poles as well as the signal ports together. When testing, set the
cut-off current settings to the value in the table above.
22. FULFILLED STANDARDS
EN/IEC 60204-1 Safety of Electrical Equipment of Machines
EN/IEC 61131-2 Programmable Controllers
EN 50178, IEC 62103 Electronic Equipment in Power Installations
23. USED SUBSTANCES
The unit does not release any silicone and is suitable for the use in paint shops.
Electrolytic capacitors included in this unit do not use electrolytes such as Quaternary Ammonium Salt Systems.
The materials used in our production process do not include the following toxic chemicals:
Polychlorinated Biphenyl (PCB), Pentachlorophenol (PCP), Polychlorinated naphthalene (PCN), Polybrominated
Biphenyl (PBB), Polybrominated Biphenyl Oxide (PBO), Polybrominated Diphenyl Ether (PBDE), Polychlorinated
Diphenyl Ether (PCDE), Polybrominated Diphenyl Oxide (PBDO), Cadmium, Asbestos, Mercury, Silica
24. PHYSICAL DIMENSIONS AND WEIGHT
Width 46mm / 1.81’’
Height 124mm / 4.88’’ Plus height of signal connector plug
Depth 127mm / 5.0’’ Plus depth of DIN-rail
Weight 700g / 1.54lbs
DIN-Rail Use 35mm DIN-rails according to EN 60715 or EN 50022 with a height of 7.5 or 15mm.
The DIN-rail height must be added to the depth (117mm) to calculate the total required installation
depth.

All parameters are specified at an input voltage of 24V, 20A output load, 25°C ambient and after a 5 minutes run-in time
unless otherwise noted. It is assumed that the input power source can deliver a sufficient output current.
