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.
Ex devices have been approved according to the ATEX
directive for use in connection with installations in
explosive areas.
WARNING
To avoid the risk of electric shock and fire, the safety instructions
of this guide 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 installation guide 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.
Repair of the device must be done by PR electronics A/S only.
In applications where hazardous voltage is connected to in-/
outputs of the device, sufcient spacing or isolation from wires,
terminals and enclosure - to surroundings (incl. neighbouring
devices), must be ensured to maintain protection against electric
shock.
Potential electrostatic charging hazard. To avoid the risk of
explosion due to electrostatic charging of the enclosure, do
not handle the units unless the area is known to be safe, or
appropriate safety measures are taken to avoid electrostatic
discharge.

SAFETY INSTRUCTIONS
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 can be used for Measurement Category II and Pollution Degree 2.
The module is designed to be safe at least under an altitude up to 2 000 m.
MOUNTING
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 this
installation guide and on the side label.
The device is provided with eld wiring terminals and shall be supplied from a
Power Supply having double / reinforced insulation. A power switch should be
easily accessible and close to the device. The power switch shall be marked as the
disconnecting unit for the device.
SYSTEM 3000 must be mounted on a DIN rail according to EN 60715.
UL installation
Use 60/75°C copper conducters only.
Wire size ........................... AWG 26-12
UL le number.................. E314307
The device is an Open Type Listed Process Control Equipment. To prevent injury
resulting from accessability to live parts the equipment must be installed in an
enclosure.
The power Supply unit must comply with NEC Class 2, as described by the National
Electrical Code®(ANSI / NFPA 70).
cFMus installation in Division 2 or Zone 2
Class I, Div. 2, Group A, B, C, D T4 or I, Zone 2, AEx nA IIC T4 or Ex nA IIC T4.
In class I, Division 2 or Zone 2 installations, the subject equipment shall be
mounted within a tool-secured enclosure which is capable of accepting one or
more of Class I, Division 2 wiring methods specied in the National Electrical
Code (ANSI/NFPA 70) or in Canada in the Canadian Electrical Code (C22.1).
The 3000 System Isolators and Converters must be connected to limited output
NEC Class 2 circuits, as outlined in the National Electrical Code® (ANSI / NFPA

When the temperature under rated conditions exceeds 70°C at the cable or
conduit entry point, or 80°C at the branching point of the conductors, the
temperature specication of the selected cable shall be in compliance with the
actual measured temperature.
Provisions shall be made to prevent the rated voltage from being exceeded by
transient disturbances of more than 40%.
For installation on power rail in Zone 2, only Power Rail type 9400 supplied by
Power Control Unit type 9410 is allowed.
To prevent ignition of the explosive atmospheres, disconnect power before
servicing and do not separate connectors when energised and an explosive gas
mixture is present.
Do not mount or remove devices from the power rail when an explosive gas
mixture is present.
Cleaning
When disconnected, the device may be cleaned with a cloth moistened with
distilled water.
