Observe the safety instructions given in Sections 2 to 8 and Section 12 when decommissioning and
disassembling the unit.
Dismantle the unit as follows:

Risk of injury if dismantled under hazardous voltage!
»
If you do not switch off the voltage before starting to dismantle the unit, you may injure
yourself and damage the product or parts of the installation.
→
Make sure that the relevant parts of the installation have been disconnected from the
voltage supply.
Careless disposal of the unit may cause pollution.
Please therefore dispose of the unit in accordance with the national requirements that apply in your
country.
Further faults may occur before and during operation of the unit.
13. Troubleshooting
Please note the following instructions:
•
Proceed systematically and purposefully when troubleshooting, even under time pressure.
In the worst case, randomly and indiscriminately dismantling and changing settings may result in it
no longer being possible to determine the original cause of the fault.
•
Get an overview of the unit‘s operation in conjunction with the overall installation.
•
Try to clarify whether the unit provided the required function in the overall installation before the fault
occurred.
•
Try to find any changes to the overall system in which the unit is installed:
•
Have the unit‘s operating conditions or operating range been changed?
•
Have any changes (e.g. reconfigurations) or repairs been performed on the overall system
(installation, electrics, control) or to the unit? If yes: what?
•
Has the unit been operated correctly?
•
How does the fault appear?
•
Form a clear idea of the cause of the fault. If necessary, question the immediate operator or the
installation operator.
If you have not been able to remove the fault, please contact the manufacturer. The contact address
can be found at www.ruck.eu or on the back cover of this assembly and operating manual.
