SYMBOL IDENTIFICATION
Triangle with an exclamation mark: Warning / demand. Potentially
lethal situations.
The CE mark proves the compliance of the device with the essential
requirements of the directives.
WARNING
This device is designed for connection to hazardous electric
voltages. 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 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.
WARNING
Until the device is fixed, do not connect hazardous voltages to
the device.
The following operations should only be carried out on a
disconnected device and under ESD safe conditions:
Troubleshooting the device.
Repair of the device must be done by PR electronics A/S
only.

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

4 5725V101-IN
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 shall be easily accessible and close to the device. The power
switch shall be marked as the disconnecting unit for the device.
UL INSTALLATION REQUIREMENTS
For use on a flat surface of a type 1 enclosure.
Use 60/75°C copper conducters only.
Enclosure rating (face only).................... Type 4X, UL50E
Max. ambient temperature..................... 60°C
Max. wire size, pins 41...46.................... AWG 30-16
Max. wire size, others ............................ AWG 30-12
UL file number........................................ E248256
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
