Security information
The DC-power-supplies of the seriesEPS/HC 40030-60 can be
operated as desktop or rack-mounting units. If they are not installed
inside cabinets or other casings, make sure that they are protected
against dropping particles, water, dust and vapor!
The manufacturer recommends installing the DC-power-supplies in
cabinets or other protective casings.
The DC power supplies are only to be operated in the permissible ranges
of current, voltage, environmental temperature and atmospheric humidity
according to the rating plate and the operating manual.

FMK0008970_4083-ESK_30V60A_1~230VAC_PFC_Ah_Ext-Sollwerte_X4_neutral_e.doc 7/41
1.3 Installation of the DC power supply modules
While mounting the module and the DC connectors, observe especially
the following:
- Don‘t tighten screws with a lever, don’t bent any rails or panels.
- The units must be mounted in a horizontal way.
- If mounting the units near the plating tanks is necessary, one has to
make sure that they are protected against chemical vapor and dust
and dropping particles.
- Ensure an unhindered airflow at the air input and air output.
- Observe the installation instructions of the electrical installation.
1.4 Operation conditions
DC power supplies are not to be operated in an explosive environment.
Ensure a sufficient airflow to avoid an internal overheating. Always install
the rectifiers directly on to a strong surface and never near an object that
may block the airflow.
Keep a distance from
at least 50cm
from air inlet and outlet to walls or other devices.
The cooling air must be free from any chemical contamination and free
from particles, steam and dust.
The unit must be protected from dropping particles, dripping water and
spalsh water.
The DC power supply should be fixed on the installation place by using
the mounting holes.
Attention!
Never use the front panel to hang up the device as shown on the
sketch below!

FMK0008970_4083-ESK_30V60A_1~230VAC_PFC_Ah_Ext-Sollwerte_X4_neutral_e.doc 8/41
2 General description
The DC-power supplytype EPS/HC 40030-60 isa sophisticated
switch mode type rectifier, designed for theindustry. It is
designed to fit in a 19”- casing.
The control of the output parameters is done by keys in the front panel of
the unit (internal setpoints mode) or via external analog set signals
(external setpoints mode). The output values are shown on the large,
illuminated display. The display can also show status and warning or
error messages.
The electronic regulation guarantees correct output parameters during
the operation, even with variable loads at the DC output.
Over temperature protection
The device is temperature protected. In case of rising interior
temperature, first the fan speed increases. If the temperature is still
increasing, the device decreases the output current automatically;
in extreme case, the output is set to zero. After a cooling phase, the
output power is increased automatically.
Attention:
Auto-re-start after cooling down!
Do not run the power supply at higher environmental temperatures
than 35°C!
2.1 Switch mode technology
This device was designed as switch mode type DC power supply. The
advantages of the switch mode technology are:
- very compact design
- maximum regulation accuracy
- very low ripple
- high efficiency; power factor cos. 0.95
2.2 PFC technology
The PFC technology (Power Factor Control) allows a reduced phase
current by increasing the efficiency of the power part.

2.3 Intended purpose
Device for industrial application
According to the norms
DIN EN 61000-3-12 (VDE 0838-12):2012-06
EN 61000-3-12:2011
this device is only to be used for industrial applications. Offering and
selling the device to the general public is not provided.
All other use must be clarified with the technical support of the
manufacturer. Otherwise, the installation or other connected devices
could be damaged.

FMK0008970_4083-ESK_30V60A_1~230VAC_PFC_Ah_Ext-Sollwerte_X4_neutral_e.doc 10/41
3 DC bus bars
The DC output bus bars are located in the rear panel of the device.
Connect the DC output of the DC power supply to the load.
Check for right polarity and proper contact.
Look for the
DIN VDE 0298-4 : 2013-06
admitted cable cross section and the correct polarity.
Attention:
The connection of active loads as batteries or DC-machines to the
DC output would cause damages to the unit!
Please check:
Do not wire the power supply cable and the DC-cables into a roll or bind
the supply cable and the DC-wiring together with other wires. Otherwise,
overheating is possible.

FMK0008970_4083-ESK_30V60A_1~230VAC_PFC_Ah_Ext-Sollwerte_X4_neutral_e.doc 11/41
4 Mains supply
Supply voltage: 230V AC +/-10% 50-60Hz
Phase current: see ”Technical data”
Use the delivered mains cable.
Mains cable specification:
The mains cable must be selected corresponding to the following
regulations:
DIN VDE 0298-4 / 2013-06
Use equivalent regulations that are valid for the country the device is
used in.
Provide for an allowable external fuse admitted to
DIN VDE 0636-2 / 2014-09 / DIN EN 60269-2
Check for the correct environmental temperature (max. 35°C).
Please check:
Make sure that the supply cables could be directly connected to your
main supply.
Avoid the use of cable extensions and multiple power sockets.
Do not wire the power supply or the DC-cables into a roll or bind the
supply and the DC-cables together with other wires. Otherwise,
overheating is possible.

5 Operation
5.1 Main switch
The DC-power-supply must be switched on by using the main switch in
the front panel (key ON / OFF, to the left hand side).
The LED between the two buttons lights up if the unit is switched on.
After connection to the main supply the following information appear on
the display:
- Checking Memory
- Memory o.k.
- Clearing memory
- Memory cleared
- Initializing memory
- Memory initialized
If the booting sequence is done the pe-logo is shown for a short time.
Afterwards the unit starts the normal operating mode.

FMK0008970_4083-ESK_30V60A_1~230VAC_PFC_Ah_Ext-Sollwerte_X4_neutral_e.doc 13/41
5.2 LCD display
In normal operating mode, the digital display shows the actual current
and voltage parameters of the connected DC power supply.
Below the current and voltage values, the parameters of the additional
functions are shown.
Depending on the operating state, the display can show special
parameters and special functions.
The display can also show error messages.
The display is backlight-illuminated.
The contrast, the display language (menu text) and the illumination can
be configured in the “additional Settings” menu.

8 The total counter
8.1 General description
The total counter allows the measurement of the actual current with
switchable measuring ranges ampere hours, ampere minutes, ampere
seconds, 1/10 000Ah and gram-silver, gram gold.
The actual counter reading is shown down in the display (line: “Total c.“)
Possible settings for the total counter
The following counting ranges are available:
Ah = Ampere hours
Am = Ampere minutes
As = Ampere seconds
0.0001Ah = 1 ten-thousandth part of ampere hour
gS = Gram silver
gG = Gram Gold (single weighted 3-weighted)
- Set decimal point
Attention
Each digit set after the decimal point reduces the digits before the
decimal point!
Example:
If you set ampere-hours with three digits after the decimal point
only two digits before the decimal point can be shown (99.999Ah).
If you set zero digits after the decimal point five digits before the decimal
point can be shown (99999Ah)
- Delete actual count
- Delete overflow indication
Attention:
The actual values (Ah, Am, As, 0.0001Ah, gS, gG) are deleted by
switching the unit or changing the decimal places!
The actual count is stored if the main switch of the unit is switched
off or if the unit is disconnected from mains.

9 External setpoints
In “External mode”, the DC power supply is controlled via external
setpoints (terminal X4, see wiring scheme).
If “External setpoints” is activated the current and voltage Up / Down
keys are deactivated.
The switching is done via key F2.
The display shows: Setpoints: extern
In “External setpoints mode”, the control signals for current and voltage
I-set and U-set are 0 … 10V each. These signals are supplied at terminal
X4.
The digital displays will show the actual output values. The readback
values are given out indirect-coupled on the X4-terminal
(signals: 0 … 10V each).
