Technische Daten
Maintenance
If repair is necessary, the affected component must be sent to the production
location. Repairs can only be carried there.
Special Conditions
1. The diagnostic repeater must be installed in a cabinet or metal housing. These
must comply with the IP 54 degree of protection as a minimum. The
environmental conditions under which the equipment is installed must be taken
into account. There must be a manufacturer's declaration for zone 2 available
for the housing (in accordance with EN 50021).
2. If a temperature of > 70 °C is reached in the cable or at the cable entry of this
housing under operating conditions, or if a temperature of > 80 °C can be
reached at the junction of the conductors under operating conditions, the
temperature-related properties of the cables must correspond to the
temperatures actually measured.
3. The cable entries used must comply with the required IP degree of protection
and Section 7.2 (in accordance with EN 50021).
4. All devices (including switches, etc.) that are connected to the inputs and
outputs of fail-safe signal modules must be approved for EEx nA or EEx nC
explosion protection.
5. Steps must be taken to ensure that the rated voltage through transients cannot
be exceeded by more than 40 %.
6. Ambient temperature range: 0° C to 60° C
7. A sign containing the following warning must be put up inside the housing in an
easily visible position when the housing is opened:
Warning
The housing can only be opened for a short time (e.g. for visual diagnostics). If
you do this, do not operate any switches, remove or install any modules or
disconnect any electrical cables (plug-in connections).
You can disregard this warning if you know that the atmosphere is not
hazardous (i.e. there is no risk of explosion).
