SYMBOL IDENTIFICATION
Triangle with an exclamation mark: Warning / demand.
Potentially lethal situations.
The CE mark proves the compliance of the module with
the requirements of the directives.
The double insulation symbol shows that the module is
protected by double or reinforced insulation.
WARNING!
This module is designed for connection to hazardous electric volt-
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
module must only be applied as described in the following.
Prior to the commissioning of the module, this manual must be
examined carefully.
Only qualified personnel (technicians) should install this module.
If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may
be impaired.
WARNING!
Until the module is fixed, do not connect hazardous voltages to
the module. The following operations should only be carried out
on a disconnected module and under ESD safe conditions:
Dismantlement of the module for setting of DIP-switches
and jumpers.
General mounting, connection and disconnection of wires.
Troubleshooting the module.
Repair of the module and replacement of circuit breakers
must be done by PR electronics A/S only.
WARNING!
To keep the safety distances, modules with two built-in relays
must not be connected to both hazardous and non-hazardous
voltages on the same module’s relay contacts.
SYSTEM 2200 must be mounted in socket type S3B Releco
(order no 7023).
GENERAL
HAZARD-
OUS
VOLTAGE
INSTAL-
LATION

The following apply to fixed hazardous voltages-connected modules:
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 module.
The power switch should be marked with a label telling it will switch off the
voltage to the module.
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 modules 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 module is easily accessible.
CLEANING:
When disconnected, the module 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.

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 module without damaging it and make sure that the manual always
follows the module and is always available. The packing should always follow the
module until this has been permanently mounted.
Check at the receipt of the module 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 modules 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
module.
Should there be any doubt as to the correct handling of the module, please
contact your local distributor or, alternatively,
PR electronics A/S, Lerbakken 10, DK-8410 Rønde, Denmark,
tel: [phone].
Mounting and connection of the module 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.

HOW TO DISMANTLE SYSTEM 2200
The back panel of the module is detached from the housing by way of a screw-
driver as shown in picture 1.
On a module 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.

SWITCHMODE
POWER SUPPLY
2220
• Mains voltage input
• Isolation 3.75 kVAC
• Adjustable output 5...24 VDC, max. 7 W
• Short-circuit protection
• Thermal overload protection
• Standard 11-pole relay socket
APPLICATIONS:
General power supply for smaller measurement systems requiring fixed stabilized
24 VDC, or supply for any other sensors, transmitters or as a general
variable power supply 5 to 24 VDC.
Two units may be connected in series for plus / minus or higher output voltage.
TECHNICAL CHARACTERISTICS:
The unit is based on secondary switchmode technology enabling an adjustable
output with a minimum loss of power. Isolation test voltage between input and
output is 3.75 kVAC. This makes the unit suitable for PELV/SELV applications. The
double-isolated safety transformer includes a 100°C thermal fuse which switches
off the input before the transformer is overheated. When the temperature returns
below 100°C the thermal fuse will automatically switch on the power supply.
MOUNTING:
The 2220 is for standard 11-pole socket mounting in all positions. To achieve
maximum cooling, vertical position and a small distance (10 mm) between
neighbouring units are recommended.
INPUT:
Standard supply voltages in accordance to the specifications. Galvanic isolation
is ensured by the double-isolated safety transformer.
