Specification:
The DCUPS2U-Series is designed as an uninterruptable power supply for telecommunication and data
application use. Its regulated DC of 90% makes the DCUPS2U robust, economical and reliable. Camtec power
supplies are traditionally made with high-end low ESR electrolytic output capacitors with withstanding
+125°C temperature. Our capacitors are rather designed over for longer lifetime and longer hold up times.
The DCUPS2U is short circuit and zero load stability protected. It has a thermal overload fuse at the output to
protect the connected load. It is protected against high transient and provides very good interference
resistance. We use IP20 stabile aluminium housings with ventilation slots in accordance to the demanding
VDE norms. The plus pole has an internal connection to ground. The AC-Line connector and the DC-Output
connector has securing clip and screw fitting to avoid accidential removal of the connected cabeling. The
DCUPS2U has a built in AC-Fail detection and the message is available at the output connector galvanic
insulated. A DC-fail-function- message for the battery charger power supply and the main power supply is
optional available; each relay is floating galvanic insulated.

a) Use approriate test equipment which apply the voltage with a slow ramp
b) Connect L1 and N together, as well as all output poles
c) Use only AC test-voltages with 50/60Hz. The output voltages is floating and has
no ohmic reference to ground.
d) If testing output voltages are ≥60Vdc remain to security directives.
Use only isolated screw drivers to adjust output voltages.

Battery Management Switch:
We advise the battery management to be switched into the off-position for shipping, storing or for service operations (battery change!). If
the switch is not in the off-position, the batteries can be damaged while beeing total discharged! The piezo warning sound of AC-main
failure and the DC-battery backup connection is disbaled while the switch is put into the off-position. To enable the battery backup and all
warnings, make sure that the battery management is put into the on-position (normal operation mode).

Mechanics & Installation:
Stable aluminium housing IP20 to allow adequate convection, a free air space of 1U (top/bottom) and 5mm (sidewalls) is required for the
DCUPS2U; for active devices 15mm space from its sidewalls. For free air convection it is necessary to install the DCUPS2U horizontal
Battery type for service replacement:
To guarantee safe function it is advised to use the same battery type as the installed one, to DC-UPS. The battery type is the Panasonic
LC-R124R5P 12V 4,5Ah . We recommend the batteries to change after 2 years cycle operation to prevent malfunctions.
Safety Instructions: Please read all warnings and advices carefully before installing or operating the DCUPS2U. Retain this operation manual
always ready to hand.The DCUPS2U must be installed by specialist staff only.
Installation:
1.) The DCUPS2U is designed for systems fulfilling the safety norms of
dangerous voltages/energy and fire prevention
2.) Installation is restricted to specialists only, make sure that the AC
wire system is free of voltage
3.) Opening the DCUPS2U, making any modifications to it, dismounting
any screws from it, operating the DCUPS2U out of specification
and/or using it in appropriate area will unevitably result in loosing
manufactureres guarantee; we decline taking any responsibility for
risk of demages caused to someones health or to any installed
system.
4.) Attention: The DCUPS2U has input fuses for the L and the N line.
Replace the fuses only with the same type; we recommend to use
the same manufacturer. The fuses must be UL-certified switch type.
It is also necessary to wire an automatic circuit braker to the line.
We suggest to use a 16A-type with B-characteristic. It is verboten to
operate the DCUPS2U without protective earth wired.
5.) It is recommended to replace the internal batteries by the same
valve regulated lead-acid battery type with Faston 197 connectors:
Panasonic LC-R124R5P. For replacing the battery please consult
your service provider or send the DCUPS2U to the manufacturer.
6.) After lifetime batteries has to be given to a cetified recycle company.
Warnings:
Disregard these warnings can cause fire, electic shock, serious
accident and death.
1. Never operate the DCUPS2U without Protective Earth
Conductor
2. Before connecting the DCUPS2U to the AC wire
system make all wires free of voltage and assure
accidently switch on
3. Allow neat and professionel cabeling
4. Never open nor try to repair the DCUPS2U by yourself.
Inside are dangerous voltages that can cause electric
shock hazard.
5. Avoid metal pieces or other conductive material to fall
into the DCUPS2U
6. Do not operate the DCUPS2U under damp or wet
conditions
7. It is verboten to operate the DCUPS2U under Ex
conditions or in Ex-Area
H= 2U = 88,1mm
B= 84WU(TE) = 426,4mm
