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 volt-

ages. 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 follow-

ing. 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.

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 2, 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

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 5725V102-UK

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
