Removing the operating panel
1) Disable the power supply.
2) Remove all electrical plugs from the operating panel.
3) Disconnect the ground cable from the ground bolt.
4) Loosen the mounting screws.
The operating pane is not ready for removal from the opening.
4.6
Air conditioning, ventilation
The operating panel has ventilation slots for heat dissipation. If the permissible
ambient temperature is not exceeded, no external fan will be needed. Make
sure that the ventilation holes are not covered.
CAUTION
High ambient temperature can destroy the operating panel!
●
The temperature inside the control cabinet may not be higher than the max-
imum permitted operating temperature of the operating panel. Please refer
to the technical data for this. If this cannot be guaranteed through natural
heat dissipation, an air conditioning of the control cabinet must be provided.
4.6.1
Use of air filters
Information
The operating panel must be installed in an appropriate housing to guarantee
that no degree of soiling greater than 2 according to EN 61131-2 occurs.
It is recommended to install the module in a dustproof, closed control cabinet.
Fan openings of the control cabinet must be equipped with air filters. The filter
elements must be cleaned or replaced regularly.
4.7
Sealing
To ensure protection type IP54 (front side), the back side of the operating panel
must be fitted with a seal (not included in the delivery of KEBA). The operating
panel with seal must be installed flush on the mounting surface.
CAUTION
●
All unused openings must be covered by appropriate blind covers (not in-
cluded in KEBA delivery). Otherwise, the tightness cannot be guaranteed.
●
Before installing the operating panel, check the surrounding seal for dam-
age. Only with an undamaged seal is the front-side protection class IP 54
ensured.
