10 Routine Maintenance & Repair 
10.1  Routine Maintenance 
Periodic inspection of the inverter should check: 
1.  For build up of dust obstructions that may obstruct the ventilation of the product. This should be 
removed using dry air. 
2.  Tightness of power connections are at the recommended terminal tightening torque as specified in 
this manual.  
 
10.2  Preventative Maintenance 
 Main Duct Cooling Fans 
The Main Duct Cooling fans are designed to be field replaceable by a competent person. 
For preventative maintenance, replace the fan cassettes every 5 years of operation, or whenever the 
inverter trips on “tr10” / “10 Heatsink Temp” during normal operation.  
 
 DC Link Capacitors 
For preventative maintenance, the DC link capacitors should be replaced every 10 years of operation, or 
when the inverter trips on “tr20” / “20 VDC Ripple” under normal operating conditions.  
The unit must be returned to your local Parker Repair Centre for replacement. 
 
10.3  Repair 
In the event of a drive failure, the inverter should be returned to a local Parker Repair Centre. No attempt 
should be made by the user to repair the unit themselves. Only Parker trained personnel are permitted to 
repair this product in order to maintain certifications, reliability, and quality levels. 
 
When returning a faulty product, the user should: 
1.  Where possible, save the application data onto either a µSD card using the ‘Clone’ feature, or onto 
a PC by performing a configuration ‘Extraction’ using the DSE configuration tool.   
2.  Contact the local Repair Centre, who will arrange the return of the unit and assign an Authorisation 
To Return (ATR) number. This is used as a reference on all paperwork returned with the faulty 
item. 
Customers should be ready with the following information: 
-  Product model and serial number (found on the product rating label) 
-  Detailed information on the nature of the fault (Trip messages, user application and 
history). 
3.  Pack and dispatch the unit using original packaging materials where retained, or in suitable 
packaging materials that ensure that no additional damage is caused to the unit during transit. 
Please ensure that if used, packing chips do not enter the unit.
