3. General Safety Information

Read the safety instructions very carefully. All safety precautions must be observed strictly while using

the product described in this manual and any associated instrumentation.

Study this document to learn how to operate your product correctly. Keep this instruction manual in

a safe place close to the described product and inform all other users of the manual’s location. Always

include this manual when handing the product over to third party persons.

Responsible body is the individual or group of persons that are responsible for the proper use and

maintenance of the product, ensuring that the product is being used within its speciﬁcations and

operating limits. The responsible body must ensure that users of the product are adequately trained.

Operators must use the product for its intended purpose. Users must be trained in electrical safety,

handling of cryogenic liquids (if applicable) and adequate use of scientific instrumentation. They must

be protected from electric shock and other potentially dangerous situations.

Maintenance Personnel perform routine tasks on the product to keep it in proper operating

conditions, i.e., setting up the line voltage or replacing consumables. Maintenance procedures

described in this manual must be followed.

Service Personnel are trained to work on live circuits and to work cryogenic liquids (if applicable) as

well as perform fault ﬁnding measurements and repair work to the product. Only fully trained service

personnel qualiﬁed to manage potentially lethal voltages may perform servicing and repair.

Shock hazard: The American National Standards Institute states that a shock hazard exists when

voltage levels are greater than 30 V RMS, 42.2 V peak or 60 VDC. A good safety practice is to assume

that hazardous voltages are present in any unknown circuitry.

Warning!

Always check for correct mains voltage before connecting any equipment!

Mains supply voltage fluctuation must not exceed ±10% of the nominal voltage.

Warning!

• Always observe and strictly follow the safety notes and regulations given in this document

• Always use the originally delivered cables with the product for all electrical connections.

• Always switch oﬀ the device before disconnecting cables.

• Never operate the device outside its dedicated environment.

• DO NOT OPEN the device unless you fulfill the requirements of a fully trained service

personnel, and you are familiar with live circuits and potentially lethal voltages.

Important! Ambient conditions and environment:

This product may only be used indoors, in locations meeting the following requirements:

• Room temperature lies between 5°C/41°F and 40°C/104°F

• Humidity up to maximum of 80%

• Altitudes up to 2000m

• Pollution Degree 2 environments

3.1 Specific Safety Precautions for the Products RECOMEC13 / RECOMCREC13V2

Only qualiﬁed personnel who recognize shock hazards and are familiar with the precautions

necessary to avoid injury shall use the products described in this manual.

Warning: Potentially Lethal Voltages!

This Product, depending on its application can operate at potentially lethal voltages of up to

300VRMS.

Any adjustment, fault-ﬁnding procedure, installation and maintenance of the product

described in this manual must be carried out only by authorized service personnel.

• In case of malfunction, immediately disconnect the unit from any power supply

• Do not touch any electrical terminals, connectors or wires

• Report damaged cabling immediately to service personnel

• Always wear electrically isolating safety shoes when performing maintenance

Warning: Liquid Nitrogen (LN2), Nitrogen Gas (N2)

• Nitrogen is a colorless, odorless, and tasteless non-toxic substance. LN2 is a clear liquid.

1 liter of liquid N2 expands to about 700 liters of gas when warming up which causes a large

pressure build-up in a closed container. Make sure to take precautions against overpressure.

• LN2/N2 can cause rapid suﬀocation without noticing. Therefore, these substances must be

stored and used in areas with adequate ventilation. Be aware that N2 gas accumulates on the

ground. If any symptoms such as drowsiness, dizziness, headache, unconsciousness or even

vomiting occur, bring victim to fresh air, provide oxygen or artiﬁcial respiration if needed. Call

for professional medical help.

• LN2 can cause severe frostbite. In case of injury, warm up exposed parts, but do not use hot

water. Seek medical assistance.

• The handling of liquid nitrogen is restricted to authorized and trained personal respecting the

general safety precautions for cryogenic liquids. Always use appropriate personal protective

equipment (PPE), i.e., wear safety glasses and gloves as well as closed stable shoes and long

sleeves/pants.

• Read all safety instruction given by your supplier of liquid nitrogen and storage vessels

carefully.
