PRODUCT DESCRIPTION
The Dimension CP-Series are cost optimized power
supplies without compromising quality, reliability and
performance.
First of all, high immunity to transients and power surges
as well as low electromagnetic emission and Marine
approvals with EMC Class B make the
CP20.245-R2 the best choice for equipment in bridge &
deck zones the same way as for oil, gas and chemical
plants.
This power supply furthermore features a DC-OK signal
contact to remotely monitor error-free operation, a
decoupling MOSFET to set-up redundant power supply
systems, and plug connector terminals to allow device
replacement while the application keeps running. The
CP20.245-R2 covers an extreme wide temperature range
from -40°C up to +60°C providing full output power.
Outstanding features of CP20.245-R2 are its high
efficiency, the electronic inrush current limitation, and an
active PFC. The devices also offer PowerBoost: Power
reserves of 20%, which may even be used continuously at
temperatures up to +45°C. Additionally, the device can
deliver about 3 times the nominal output current for
12ms which helps to trip fuses on faulty output branches.

NSTALLATION INSTRUCTIONS
WARNING
Risk of electrical shock, fire, personal injury or death.
- Turn input power off before working on the device. Protect against inadvertent re-powering.
- Make sure that the wiring is correct by following all local and national codes.
- Do not modify or repair the unit.
- Do not open the unit as high voltages are present inside.
- Use caution to prevent any foreign objects from entering the housing.
- Do not use in wet locations or in areas where moisture or condensation can be expected.
- Do not touch during power-on, and immediately after power-off. Hot surfaces may cause burns.
Obey the following installation instructions:
This device may only be installed and put into operation by qualified personnel.
This device does not contain serviceable parts. The tripping of an internal fuse is caused by an internal defect.
If damage or malfunction should occur during installation or operation, immediately turn power off and send unit to the
factory for inspection.
Install the device in an enclosure providing protection against electrical, mechanical and fire hazards.
Install the device onto a DIN-rail according to EN 60715 with the input terminals on the bottom of the device. Other
mounting orientations require a reduction in output current.
Make sure that the wiring is correct by following all local and national codes. Use appropriate copper cables that are
designed for a minimum operating temperature of 60°C for ambient temperatures up to +45°C, 75°C for ambient
temperatures up to +60°C and 90°C for ambient temperatures up to +70°C. Ensure that all strands of a stranded wire enter
the terminal connection. Unused screw terminals should be securely tightened.
The device is designed for pollution degree 2 areas in controlled environments. No condensation or frost is allowed.
The enclosure of the device provides a degree of ingress protection of IP20. The housing does not provide protection against
spilled liquids.
The isolation of the device is designed to withstand impulse voltages of overvoltage category III according to IEC 61010-2-201.
The device is designed as “Class of Protection I” equipment according to IEC 61140. Do not use without a proper PE
(Protective Earth) connection.
The device is suitable to be supplied from TN, TT or IT mains networks. The continuous voltage between the input terminals
and the PE potential must not exceed 300Vac.
The input can also be powered from a battery or a similar DC source. The continuous voltage between the supply voltage and
the PE/ground potential must not exceed 375Vdc.
A disconnecting means shall be provided for the input of the device.
The device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do not cover
ventilation grid!
The device is designed for altitudes up to 6000m. Above 2000m a reduction in output current and over voltage category is
required.
Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 5mm left and right side. Increase
the 5mm to 15mm in case the adjacent device is a heat source. When the device is permanently loaded with less than 50%,
the 5mm can be reduced to zero.
The device is designed, tested and approved for branch circuits up to 32A (IEC) and 30A (UL) without additional protection
device. If an external fuse is utilized, do not use circuit breakers smaller than 10A B- or C-Characteristic to avoid a nuisance
tripping of the circuit breaker.

Above 45°C, do not use this power/ current longer than a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes.
**) HiccupPLUS®Mode
At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2s. After this, the
output is switched off for approx. 18s before a new start attempt is automatically performed. This cycle is repeated as long as the
overload exists. If the overload has been cleared, the device will operate normally. See Fig. 6-2.

*) The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by the lifetime
expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is calculated according to
the capacitor’s manufacturer specification. The manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15
years (131 400h). Any number exceeding this value is a calculated theoretical lifetime which can be used to compare devices.
**) MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a
device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product.
The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h means that
statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it cannot be determined if the failed
unit has been running for 50 000h or only for 100h.

The output voltage is floating and has no ohmic connection to the ground. Type and factory tests are conducted by
the manufacturer. Field tests may be conducted in the field using the appropriate test equipment which applies the
voltage with a slow ramp (2s up and 2s down). Connect all input-terminals together as well as all output poles before
conducting the test. When testing, set the cut-off current settings to the value in the table below.

To fulfil the PELV requirements according to EN60204-1 § 6.4.1, we
recommend that either the + pole, the – pole or any other part of
the output circuit shall be connected to the protective earth
system. This helps to avoid situations in which a load starts
unexpectedly or cannot be switched off when unnoticed earth
faults occur.
B*) When testing input to DC-OK ensure that the max. voltage between DC-OK and the output is not exceeded (column D). We recommend
connecting DC-OK pins and the output pins together when performing the test.
