1. Safety Instructions and Responsibility

1.1. General Safety Instructions

This operation manual is a significant component of the unit and includes important rules and
hints about the installation, function and usage. Non-observance can result in damage and/or
impairment of the functions to the unit or the machine or even in injury to persons using the
equipment!

Please read the following instructions carefully before operating the device and observe all safety
and warning instructions! Keep the manual for later use.

A pertinent qualification of the respective staff is a fundamental requirement in order to use
these manual. The unit must be installed, connected and put into operation by a qualified
electrician.

Liability exclusion: The manufacturer is not liable for personal injury and/or damage to property
and for consequential damage, due to incorrect handling, installation and operation. Further
claims, due to errors in the operation manual as well as misinterpretations are excluded from
liability.

In addition the manufacturer reserve the right to modify the hardware, software or operation
manual at any time and without prior notice. Therefore, there might be minor differences
between the unit and the descriptions in operation manual.

The raiser respectively positioner is exclusively responsible for the safety of the system and
equipment where the unit will be integrated.

During installation or maintenance all general and also all country- and application-specific safety
rules and standards must be observed.

If the device is used in processes, where a failure or faulty operation could damage the system or
injure persons, appropriate precautions to avoid such consequences must be taken.

1.2. Use according to the intended purpose

The unit is intended exclusively for use in industrial machines, constructions and systems. Non­conforming usage does not correspond to the provisions and lies within the sole responsibility of
the user. The manufacturer is not liable for damages which has arisen through unsuitable and
improper use.

Please note that device may only be installed in proper form and used in a technically perfect
condition in accordance to the “Technical Specifications” (see chapter 6).

The device is not suitable for operation in explosion-proof areas or areas which are excluded by
the EN 61010-1 standard.

1.3. Installation

The device is only allowed to be installed and operated within the permissible temperature range.
Please ensure an adequate ventilation and avoid all direct contact between the device and hot or
aggressive gases and liquids.

Before installation or maintenance, the unit must be disconnected from all voltage-sources.
Further it must be ensured that no danger can arise by touching the disconnected voltage­sources.

Devices which are supplied by AC-voltages, must be connected exclusively by switches,
respectively circuit-breakers with the low voltage network. The switch or circuit-breaker must be
placed as near as possible to the device and further indicated as separator.

Incoming as well as outgoing wires and wires for extra low voltages (ELV) must be separated
from dangerous electrical cables (SELV circuits) by using a double resp. increased isolation.

All selected wires and isolations must be conform to the provided voltage- and temperature­ranges. Further all country- and application-specific standards, which are relevant for structure,
form and quality of the wires, must be ensured. Indications about the permissible wire cross­sections for wiring are described in the “Technical Specifications” (see chapter 6).

Before first start-up it must be ensured that all connections and wires are firmly seated and
secured in the screw terminals. All (inclusively unused) terminals must be fastened by turning the
relevant screws clockwise up to the stop.

Overvoltages at the connections must be limited to values in accordance to the overvoltage
category II.

For placement, wiring, environmental conditions as well as shielding and earthing/grounding of
the supply lines the general standards of industrial automation industry and the specific shielding
instructions of the manufacturer are valid.

1.4. Cleaning, Maintenance and Service Notes

To clean the front of the unit please use only a slightly damp (not wet!), soft cloth. For the rear no
cleaning is necessary. For an unscheduled, individual cleaning of the rear the maintenance staff
or assembler is self-responsible.

During normal operation no maintenance is necessary. In case of unexpected problems, failures
or malfunctions the device must be shipped for back to the manufacturer for checking, adjustment
and reparation (if necessary). Unauthorized opening and repairing can have negative effects or
failures to the protection-measures of the unit.
