SYMBOL IDENTIFICATION
Triangle with an exclamation mark: Read the manual before installation
and commissioning of the device in order to avoid incidents that could lead
to personal injury or mechanical damage.
The CE mark proves the compliance of the device with the essential
requirements of the directives.
The double insulation symbol shows that the device is protected by
double or reinforced insulation.
Ex devices have been approved according to the ATEX directive for use in
connection with installations in explosive areas.
SAFETY INSTRUCTIONS
DEFINITIONS
Hazardous voltages have been defined as the ranges: 75...1500 Volt DC, and
50...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.
WARNING
The following operations should only be carried out on a discon-
nected device and under ESD-safe conditions:
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
Do not open the front plate of the device as this will cause dama-
ge to the connector for the display / programming front PR 4501.
This device contains no DIP-switches or jumpers.

9113 - Product Version 9113-004 3
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.
The device must be installed in pollution degree 2 or better.
The device is designed to be safe at least under an altitude up to 2 000 m.
MOUNTING
Only technicians who are familiar with the technical terms, warnings, and instruc-
tions 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
The use of stranded wires is not permitted for mains wiring except when wires
are fitted with cable ends.
Descriptions of input / output and supply connections are shown in the block
diagram and on the side label.
The device is provided with field wiring terminals and shall be supplied from
a Power Supply having double / reinforced insulation. A power switch shall be
easily accessible and close to the device. The power switch shall be marked as
the disconnecting device for the device.
For installation on Power Rail 9400 the power is supplied by Power Control
module 9410.
Year of manufacture can be taken from the first two digits in the serial number.
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.

4 9113 - Product Version 9113-004
NORMAL OPERATION
Operators are only allowed to adjust and operate device 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 DEMOUNT SYSTEM 9000
