R8D0-MIO* Installation
Depending on the application, the R8D0-MIO* must be mounted in a suitable environment.
If mounted in Zone 2 for an Ex ec application, the environment (housing or enclosure) must
ensure the following:
IP54 in accordance with IEC 60529 for hazardous area Zone 2
■
Pollution degree 2 or better according to IEC/EN 60664-1
■

R8D0-MIO* Cable and Connection Information

Danger!
Explosion hazard from insufficient insulation
Insufficient dielectric strength of insulators between intrinsically safe circuits may lead to
interferences and to charge transfers that cause sparks. These sparks can ignite a potentially
explosive atmosphere.
Ensure that the dielectric strength of the insulation between intrinsically safe circuits is at least
500 V according to IEC/EN 60079–14.
Danger!
Explosion hazard or danger to life from inadequate installation of cables and connection lines
If you do not install cables and connection lines according to the instructions given in the
instruction manual, this can generate sparks that can ignite the surrounding potentially
explosive atmosphere. Furthermore, insufficient installation practice can result in electric
shock.
Ensure you carry out any cable gland installations in accordance with the instructions given in
the instruction manual.
Danger!
Explosion hazard from connection damage
Manipulating connections outside of the specified ambient temperature range can lead to
material damage, resulting in an unwanted failure of the connection. This could result in an
increased explosion hazard in potentially explosive atmospheres.
Only manipulate connections in the specified ambient temperature range. 
Temperature range: -5 C° ... +70 C°
Danger!
Danger to life from incorrect installation
Incorrect installation of cables and connection lines can compromise the function and the
electrical safety of the device.
Observe the permissible core cross section of the conductor.
■
When using stranded conductors, crimp wire end ferrules on the conductor ends.
■
Use only one conductor per terminal.
■
When installing the conductors the insulation must reach up to the terminal.
■
Observe the tightening torque of the terminal screws.
■
The following section describes the different connection details of the multi-input/output with
particular reference to the torques required for a safe installation.
