Wolf CFL-WRG - 10 Maintenance Shutdown

233065065_201704
Before starting any maintenance work, switch OFF the mains isolator and safeguard against unauthorised reconnection.
If the isolator is switched back on unintentionally, maintenance staff or others in the vicinity could be at risk from
rotating parts.
Wait for the fans to come to a complete standstill before opening the doors (approx. 2 minutes). Also observe the
clearly visible warning on the unit. When the doors are opened, negative pressure may draw in loose objects, which
could destroy the fan or even cause a risk to life.
Voltage is still present at terminals and connections of the EC fans even when the unit has been shut down.
This means there is a risk of electric shock that could result in injury or death.
- Do not touch the EC fans for ve minutes after disconnecting the power across all poles.
- Use a rubber mat if working on the unit when it is electrically charged.
