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.

The CE mark proves the compliance of the device with the essential requirements of the directives.

WARNING

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. Can be used in overvoltage Category II and Pollution Degree 2. The devices are 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).

Page 6

Cleaning

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

Page 7

MOUNTING ON DIN RAIL

The DRSL devices can easily be mounted on a standard 35 mm DIN rail.

Remove the DRSL Series units from the rail by lifting the DIN rail mounting clip.

Wire size AWG 26-12 / 0.13 x 2.5 mm Screw terminal torque 0.5 Nm.

stranded wire.

Page 8

INSTALLATION ON DIN RAIL

To avoid short circuit between the power rail connectors on the DRSL-TC-ISO and DRSL-RTD-ISO devices and the screws holding the 7.5 mm DIN rail, the head of the screws shall be no more than 3.5 mm high.

MODULE STOP

Module stop (DRSL-MOD-STOP)

Page 9

FLEXIBLE SUPPLY

The DRSL-TC, DRSL-RTD, DRSL-TC-ISO, and DRSL-RTD-ISO devices are powered by 24 VDC +/- 30%. 2.5 A equals 60 W - this means that up to 85 units can be energized by connecting the source in parallel with the power terminals of each unit.

External protective fuse: 2.5 A.

Power rail solution:

Alternately, you can connect 24 VDC to one DRSL-TC-ISO or DRSL-RTDISO device, which will energize up to 10 other units on the power rail.

External protective fuse: 0.4 A.

DRSL-PCU

Power rail solution:

The DRSL-PCU power connector unit allows easy connection of your 24 VDC/

2.5 A source to the power rail. Up to 85 of the DRSL-TC-ISO and DRSL-RTDISO units can be powered this way.

External protective fuse: 2.5 A.

External fuse characteristics:

The 2.5 A fuse must break after not more than 120 seconds at 6.4 A.

Page 10

MARKING

The hinged cover of the DRSL series has

a space designed to accept a snap-on marker, which can be used to identify individual units.

This space measures 5 x 7.5 mm, and

markers from Weidmuller’s MultiCard System, type MF 5/7.5, are suitable.
