Replacing a module in a CAPACITY multi-module system

WARNING: All the operations in this section must be performed by authorised and trained personnel. By
opening or removing the UPS modules and module covers you run risk of exposure to dangerous voltages!
WARNING: When removing a UPS module wait for at least 2 minutes after it has been disconnected in
order to allow the DC Capacitors to fully discharge.

WARNING: Two persons are needed to pull out the module from the UPS Frame. The weight of a DPA 50,
40kW module is 60kg. Employ suitable lifting aids and safety platforms where possible.
If a UPS module fails and there is not enough capacity left to protect the load by the remaining operating UPS modules,
the load will automatically transfer to the (static) bypass and continue to be supplied from the mains supply.
