Adhere strictly to the operating instructions before you either change
switches, or connect sockets, marked with this symbol!

1. Safety Instructions

The units of the series MCP deliver dangerously High Voltages! Ensure that
nothing and nobody will be endangered by this High Voltage before putting the
unit into operation!

Attention ! The full dielectric strength of the high voltage connectors is only achieved if

fully mated together.

Preparing for commissioning Make sure that you have read and understood the operating instruction manual!

Ensure that you observe all the hints and warnings contained within it. In not following
the operating instructions, you contravene the safety regulations for operating units of
this type. FuG accepts no liability for consequences arising from the failure to follow
these safety instructions.

Mains voltage Check whether the input voltage for your power supply, noted on the type label,

corresponds to your actual mains voltage.

Earth The unit is provided with a safety earth (German safety class I). For protection against

electric shocks, the unit must be connected to the mains via a suitable 3 or 5-pole
cable with a non-fused earth conductor. For electrical potential equalization to the load
and to the center of the AC-supply, the earth stud must be used.

High leakage current! Labeled by a sticker on the rear. At a high leakage current is an earth connection to

the Earth stud mandatory.

Operating environment The units may only be operated in a clean, dry environment.

Please make sure that no objects or liquids can enter the casing through the
ventilating apertures.
Because of the risk of sparks, the unit must not be operated in the vicinity of
flammable gases or fumes.

Cooling To ensure an adequate cooling, the ambient temperature must not exceed 40°C.

This unit is air cooled by convection or at units >700W by forced ventilation.
Therefore please ensure that an adequate air-flow is available and that nothing is
placed either above or below the unit which may impede this air-flow.
Do not operate table top units without the mounted legs and do not expose the unit
directly to solar radiation.

If the unit is used as a plug-in component, sufficient air-flow must be provided,

(1HU = 44,5 mm above and below clear).

Opening the unit Before opening, ensure that the unit is disconnected from the mains!

The unit may be opened by operating personnel only for the purpose of operating
switches as described in the operating instructions, (e.g. baud rate switch of Probus V,
which is inside).

Danger: The electronic boards inside the power supply are connected to one output pole

and can therefore lie on up to 2000V during operation.

ATTENTION! The unit contains capacitors, which discharge only very slowly (typical

discharge time 5 min) or, in worst case, do not discharge at all.

For switch over use isolated tools only.

Maintenance or repair of this unit should only be carried out by trained service

personnel who are aware of the inherent dangers of such equipment.

2. General

The units of the series MCP (Medium Voltage Chopper Power Supplies) are high
stable DC- power supplies with low ripple.

High Voltage Output ATTENTION! The units supply dangerously HIGH VOLTAGE!
Polarity Both output terminals are floating (not with option analog programming), either the

negative or the positive pole can be connected to earth.

Output Isolation At units up to 350 V nominal voltage each output terminal may float up to ±500 V with

respect to earth, from 650 V to 2000 V nominal voltage up to ±2000 V.
At units with analog programming (not floating) from 650 V on one pole is internally
connected to earth.

Short-circuit Protection All units are short-circuit proof. The maximum current can be supplied for all output

voltages, even in case of a short-circuit.

ATTENTION! During short-circuit or flash over, the internal filter-capacitors will be

discharged very fast. The output current is only limited by internal safety
resistors and can reach a value 500 times higher than the nominal value.

Load Types The type of load is optional. All passive bipolar loads can be connected.
Series Connection A series connection is possible, paying attention to the stated output isolation. That

means at a series connection of power supplies the sum voltage of both power
supplies may not exceed the mentioned value.

Parallel Connection Parallel connection of power supplies with similar nominal voltage is supported.
Type Number From the type number you can see both the power class and the maximum output

voltage of the unit.
Example: MCP 14 - 2 000 = Power class 14W / Nominal voltage 2 000V
Modifications Modified types with differing electrical or mechanical data are indicated by a "M" within

the type number, or are marked with a label “modifiziert” or "modified"

(e.g. MCP 35M - 2000).

(In this case pay attention to the description in section 8)
Serial Number The label on the rear of the unit, the technical manual and the circuit diagrams show

the serial number.

It has the following content:

Serial No.:

AAAAA-PP-NN YYYY/MM

Internal order number
Item number
Consecutive number out of this item
Deliv ery Year / Month

IMPORTANT Please indicate on all further enquiries for warranty, service or spare parts

orders the serial number and the model number of the unit.

2.1 Setup Information

Operating position The units may only be operated in horizontal position.
Class of pollution The units are designed for the pollution class 1 (normal, not conductive pollution).
EMC The units are built according to current standards. When length of signal- and control

lines up to 3m length.
Transport If the power supply is equipped with lifting appliances or handles, the weight of the unit

must be shared to these points.

2.2 Preparation for commissioning

Mains Voltage Check whether the input voltage for your power supply, noted on the type label,

corresponds to your actual mains voltage.

Use only the enclosed delivered mains cable.
Earth, Safety Conductor The unit is provided with a safety earth (German safety class I). For protection against

electric shocks, the unit must be connected to the mains via a suitable 3 or 5-pole

cable with a non-fused earth conductor.

For electrical potential equalization to the load and to the center of the AC-supply, the

earth stud must be used.

High leakage current! When this sticker is placed on the rear side of the unit or the text “High leakage

current” is engraved , the unit must be grounded properly by using the appropriate

grounding bolt with a cable of at least 10 mm ² cross section.

Fuses Internal: See type label.

External: On mains side next higher size, characteristics delay-action or if automatic

cut-out is used, characteristics "C" or "K".
Load connection The output is floating. Pay attention to the in section "2. General" stated voltage limits

for the output isolation.

The load always has to be connected between the positive and the negative output

terminal of the power supply. The return current must not flow back via mains earth!

The screen of the HV- cable always must be connected at earth potential.
Max. isolation voltage: up to 350V nominal voltage -> ± 500V

from 650V nominal voltage -> ± 2000V

At units up to 350 V output voltage use only safety connectors according

IEC 1010-1 or VDE 0110.

At units from 650 V on use the enclosed connector only.
Attention! Please obtain the limitation of isolation at units with option “analog

programming”.

See section 6.1 “analog programming”
