3.4.1
Installation site
}
Do not position the device close to highly flammable materials.
}
When installing the device within a control cabinet, you must ensure the ventilation slots
are not obstructed. otherwise the device could be damaged through overheating.
}
Protect the device from direct sunlight and dust.
}
Please note the guidelines given under “Installation”.
3.4.2
Measures to protect against interference
}
If necessary, use bulkhead separators to protect the unit from sources of interference.
}
Inductive loads within the environment (e.g. contactor, relay and solenoid valve coils)
should be wired using suppression elements (e.g. RC elements). This is particularly im-
portant if these inductive loads are fed from the same supply.
}
The power cables and the data cables should be physically separated from each other
in their own conduits (recommended minimum distance: 10 cm/3.94"). This will avoid in-
ductive and capacitive interference.
}
The prescribed earth point
for the functional earth guarantees compliance with
noise immunity requirements.
Connect the functional earth to the central earth point in star form. A cable cross sec-
tion of at least 1.5 mm² should be used for the connection. Connections should be kept
as short as possible.
3.4.3
Voltage supply
}
The supply voltage must be +24 V DC
CAUTION!
Safe electrical isolation must be ensured for the external power supply gen-
erating the 24 V voltage supply. Failure to do so could result in electric
shock. Power supplies must conform to DIN VDE 0551/EN 60742 and
EN 50178.
3.4.4
Operation
}
Plan the system correctly to ensure that a communication error between the PMI and
the host computer does not cause a malfunction.
}
Do not operate the touchscreen interface using hard or heavy objects or apply excess-
ive pressure.
}
The maximum ambient temperature must not be exceeded when using the unit.
}
Do not pour liquids over the unit or insert any objects into the unit.
}
When in storage and during operation, protect the unit from vibration and shock.
}
Avoid using chemicals close to the system.
