10.2 Periodic inspection & preventive maintenance
The recommended periodic preventive inspection and maintenance for the motor controller and associated
components are minimal. Parker recommends that the below items are done regularly. Refer also to chapter
3.
WARNING
High voltage - risk of electric chock
Disconnect the battery power supply before starting any work on the vehicle.
WARNING
High voltage - risk of personnel injury and/or damage to equipment
To prevent personnel injury and protect the AC Drive from possible damage due to voltage
transients, the AC Drive’s internal filter capacitors shall be discharged as described in the
instruction below. Do not short the + to B- terminal as this may cause an arc.
WARNING
Hot surfaces - risk of personnel injury
After operation of the motor controller, the heat sink may be too hot to touch. Allow it to cool
before performing any maintenance work on the motor controller.
CAUTION
Water sensitive equipment - risk of damage to equipment
Do not clean the motor controller using high-pressure water.
1. Wait 5 minutes for the internal filter capacitors to self-discharge, or apply a 100
Ω
(10W)
resistance between B+ and B- terminals for 15 seconds to discharge the filter
capacitors. Check that the voltage b and B- is below 10V DC.
2. Check bolt torque at terminal posts according to the values in chapter 10.6.
3. Verify vehicle functional safety.
4. Reconnect the battery power supply.
