WARNING
Please observe the following before commencing any repair work on the IRC5
controller, or units connected to the controller:
• Switch off all electric power supplies with the power switch!
• Before handling, make sure you are grounded through a special ESD wrist
bracelet or similar. Many components inside the module are sensitive to
ESD (ElectroStatic Discharge) and can be destroyed if exposed to discharge.
See the Safety chapter,
Action
Inspect all sealing joints and cable
glands to make sure they are airtight
in order to prevent dust and dirt from
penetrating into the controller cabinet.
Inspect connectors and cabling to
make sure they are securely fastened
and cabling not damaged.
Inspect the drive system fans and air
channels in the controller to make sure
they are clean.
WARNING
The fan unit must not be covered.
Check that nothing covers or block the
fan unit.
After cleaning:
• Temporarily turn the power sup-
ply to the modules on.
• Inspect all fans to make sure
they function correctly.
• Turn the power supply back off.
Replace any malfunctioning fans as
described in Replacement of drive
system fans on page 216.
