1.4 Intended Use
The devices are only approved for appropriate and intended use.
The device must only be operated in the ambient temperature range and at the relative
humidity (non-condensing) specified.
The devices are used in C&I technology for the galvanic isolation of C&I signals such as 20
mA and 10 V standard signals or alternatively for adapting or standardizing signals.
Devices that incorporate intrinsically safe circuit are used for operating intrinsically safe
field devices in hazardous areas.
1.5 Improper Use
Protection of the operating personnel and the overall system is not ensured if the product
is not being used according to its intended purpose.
The equipment is not suitable for isolating signals in high current applications unless this is
noted separately in the corresponding datasheet.
1.6 Mounting/Installation
Prior to mounting, installation, and commissioning of the device you should make yourself
familiar with the device and carefully read the instruction manual.
The device must not be installed at locations where corrosive vapors may be present.
The devices fulfill a degree of protection IP 20 according to IEC/EN 60529.
The devices are designed for use in pollution degree 2 and overvoltage category II as per
IEC/EN 60664-1.
If used in areas with higher pollution degree, the devices need to be protected accordingly.
Only use power supplies that provide protection against direct contact for the connection to
power feed modules.
Observe the tightening torque of the terminal screws.
The installation instructions in accordance with IEC/EN 60079-14 must be observed.
Intrinsically safe circuits of associated apparatus (installed in safe areas) can be led into
