‣

Use only original spare parts and accessories from the manufacturer.

Hazardous area

To eliminate danger to persons or the facility when the device is used in the hazardous

area (e.g. explosion protection):

‣

Check the nameplate to verify if the device ordered can be put to its intended use in the

hazardous area.

‣

Observe the specifications in the separate supplementary documentation that is an

integral part of these instructions.

2.5  

Product safety

This device is designed in accordance with good engineering practice to meet state-of-the-

art safety requirements, has been tested, and left the factory in a condition in which it is

safe to operate.

2.6  

Installation instructions

• The device's IP20 degree of protection is intended for a clean and dry environment.

• Do not expose the device to mechanical and/or thermal stress that exceeds the specified

limits.

• The device is intended for installation in a cabinet or similar housing. The device may

only be operated as an installed device.

The cabinet must meet the fire protection housing requirements according to safety

standard UL/IEC 61010-1 and provide adequate protection against electric shock or

burns.

• To protect against mechanical or electrical damage, the device must be installed in an

appropriate housing with a suitable degree of protection according to IEC/EN 60529.

• The device fulfills the EMC regulations for the industrial sector (EMC Class A). It can

cause electrical interference if used in residential environments.

• During installation, repair and maintenance work, the device must be disconnected from

all effective power sources if the power sources are not SELV or PELV circuits.

• Only use copper cables with a permitted temperature range (60 °C / 75 °C) as the

connection cable.
