1. General information

WARNING!

Before installation, usage and operation, ensure that the appropriate temperature

transmitter/switch has been selected in terms of measuring range, design and specic

measuring conditions.

Non-observance can result in serious injury and/or damage to

the equipment.

WARNING!

Observe the working conditions in accordance with chapter 3 “Specications”.

Further important safety instructions can be found in the individual chapters of these

operating instructions.

2.1 Intended use

The temperature transmitter/switch is used to convert temperature into an electrical signal indoors and

outdoors.

The instrument has been designed and built solely for the intended use described here, and may only

be used accordingly.

The technical specications contained in these operating instructions must be observed. Improper

handling or operation of the temperature switch outside of its technical specications requires the

instrument to be taken out of service immediately and inspected by an authorized NOSHOK service

engineer.

The manufacturer shall not be liable for claims of any type based on operation contrary to the intended

use.

2. Safety

2.2 Personnel qualication

WARNING!

Risk of injury should qualication be insu󰀩cient!

Improper handling can result in considerable injury and damage to equipment.

The activities described in these operating instructions may only be carried out by skilled

personnel who have the qualications described below.

Skilled personnel

Skilled personnel are understood to be personnel who, based on their technical training, knowledge

of measurement and control technology and on their experience and knowledge of country-specic

regulations, current standards and directives, are capable of carrying out the work described and

independently recognising potential hazards.

Special operating conditions require further appropriate knowledge, e.g. of aggressive media.

2.3 Special hazards

WARNING!

For hazardous media such as oxygen, acetylene, ammable or toxic gases or liquids,

and refrigeration plants, compressors, etc., in addition to all standard regulations, the

appropriate existing codes or regulations must also be followed.

WARNING!

Residual media in the dismounted temperature switch can result in a risk to persons, the

environment and equipment.

Take su󰀩cient precautionary measures.
