ages. Ignoring this warning can result in severe personal injury or
mechanical damage.
To avoid the risk of electric shock and fire, the safety instructions
of this manual must be observed and the guidelines followed. The
electrical specifications must not be exceeded, and the device
must only be applied as described in the following.
Prior to the commissioning of the device, this manual must be
examined carefully.
Only qualified personnel (technicians) should install this device.
If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be
impaired.

Until the device is fixed, do not connect hazardous voltages to the
device. The following operations should only be carried out on a

HAZARDOUS

VOLTAGE

disconnected device and under ESD safe conditions:
Dismantlement of the device for setting of DIP switches
and jumpers.
General mounting, connection and disconnection of wires.
Troubleshooting the device.

Repair of the device and replacement of circuit breakers must
be done by PR electronics A/S only.

WARNING

To keep the safety distances, devices with two built-in relays must
not be connected to both hazardous and non-hazardous voltages

WARNING

INSTAL­LATION

on the same device’s relay contacts.
SYSTEM 2200 must be mounted in socket type S3B Releco (order
no 7023).

SYMBOL IDENTIFICATION

Triangle with an exclamation mark: Warning / demand. Potentially lethal

situations.

The CE mark proves the compliance of the device with the requirements
of the directives.

The double insulation symbol shows that the device is protected by
double or reinforced insulation.

SAFETY INSTRUCTIONS

DEFINITIONS

Hazardous voltages have been defined as the ranges: 75 to 1500 Volt DC, and 50
to 1000 Volt AC.
Technicians are qualified persons educated or trained to mount, operate, and also
troubleshoot technically correct and in accordance with safety regulations.
Operators, being familiar with the contents of this manual, adjust and operate the
knobs or potentiometers during normal operation.

RECEIPT AND UNPACKING

Unpack the device without damaging it. The packing should always follow the
device until this has been permanently mounted. Check at the receipt of the device
whether the type corresponds to the one ordered.

ENVIRONMENT

Avoid direct sunlight, dust, high temperatures, mechanical vibrations and shock, as
well as rain and heavy moisture. If necessary, heating in excess of the stated limits
for ambient temperatures should be avoided by way of ventilation.
All devices fall under Installation Category II, Pollution Degree 1, and Insulation
Class II.

MOUNTING

Only technicians who are familiar with the technical terms, warnings, and
instructions in the manual and who are able to follow these should connect the
device.
Should there be any doubt as to the correct handling of the device, please contact
your local distributor or, alternatively,

PR electronics A/S

Mounting and connection of the device should comply with national legislation for
mounting of electric materials, i.a. wire cross section, protective fuse, and location.
Descriptions of Input / Output and supply connections are shown in the block
diagram and side label.

The following apply to fixed hazardous voltages-connected devices:
The max. size of the protective fuse is 10 A and, together with a power switch, it
should be easily accessible and close to the device.
The power switch should be marked with a label telling it will switch off the volt­age to the device.

CALIBRATION AND ADJUSTMENT

During calibration and adjustment, the measuring and connection of external
voltages must be carried out according to the specifications of this manual.
The technician must use tools and instruments that are safe to use.

NORMAL OPERATION

Operators are only allowed to adjust and operate devices that are safely fixed in
panels, etc., thus avoiding the danger of personal injury and damage. This means
there is no electrical shock hazard, and the device is easily accessible.

CLEANING

When disconnected, the device may be cleaned with a cloth moistened with
distilled water.

LIABILITY

To the extent the instructions in this manual are not strictly observed, the custom­er cannot advance a demand against PR electronics A/S that would otherwise exist
according to the concluded sales agreement.

HOW TO DISMANTLE SYSTEM 2200

The back panel of the device is detached from the housing by way of a screw-driver
as shown in picture 1.
On a device with knobs, these may have to be removed before the PCB can be
taken out as shown in picture 2.
After this, the back panel can be pulled out together with the PCB, but please
notice the position of the PCB as there is a number of different positions in the
house. Do not pull the wires unnecessarily, instead pull the PCB, see picture 3.
Switches and jumpers can now be moved.
When assembling the back plate and housing, please make sure no wires are stuck.

and housing.

SWITCHMODE POWER SUPPLY

2222

• 230 or 115 VAC primary voltage

• 24 or 15 VDC output voltage

• Double isolation by 3.75 kVAC

• 48 Watt output power, short circuit-protected

• Thermal protection against overload

• DIN rail mounting on a standard 11-pole relay socket

Applications

General 24 or 15 VDC supply for equipment that requires a stabilised DC voltage.
Separation of circuits in safety installations according to the PELV/SELV norm. Two
units can be connected in series to achieve a plus / minus supply or a higher output
voltage. The small mechanical dimensions of the switchmode power supply allow
for a high DC output power, even in narrow spaces.

Technical characteristics

The power supply is based on primary switchmode technology to achieve a high
efficiency. Galvanic isolation between the primary and the secondary voltage is
achieved through the double-isolated safety transformer. A thermal fuse protects
the input circuit when the internal temperature exceeds 100°C.
An 1 A fuse on the input protects the switchmode power supply against a short
overload. The DC output is protected against a short circuit by an electronic current
limiter that activates at an output current of 2.5 A. A green LED on the front of the
module indicates an active primary voltage.

Mounting

To achieve maximum cooling of the module, mounting in a vertical position at a
distance of minimum 10 mm between neighbouring units is recommended.

Input

AC power supply according to the specifications.
