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.

and replacement of jumpers.

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.
