GENERAL

HAZARD-

OUS

VOLTAGE

CAUTION

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 OMEGA Engineering only.

In applications where hazardous voltage is connected to in-/
outputs of the device, su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.

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.

WARNING

The CE mark proves the compliance of the device with the

essential requirements of the directives.

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 field 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.
DRSL Series must be mounted on a DIN rail according to EN 60715.

UL installation

Use 60/75°C copper conductors only.

Wire size ................................... AWG 26-12

UL file number........................ E70366

The device is an Open Type Listed Process Control Equipment. To prevent injury
resulting from accessibility 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).

3

Cleaning

When disconnected, the device may be cleaned with a cloth moistened with
distilled water.

INSTALLATION ON DIN RAIL

The front cover of the 3100 series

has been designed with an area
for affixation of a click-on marker.
The area assigned to the marker
measures 5 x 7.5 mm. Markers
from Weidmüller’s MultiCard
System, type MF 5/7.5, are
suitable.
