EM-238/363
The module automatically recognises the power failure and disconnects from the mains.
After on-site load shedding of all consumers not eligible for emergency power, and opening of the on-site
mains coupling switch, the module can switch to emergency power. After restoration of the power supply
and a brief power steadying phase, the module is shut down and the on-site mains coupling switch is
closed. The module then runs according to standard mode.
As heat is still generated in emergency power mode, adequate provision must be made to transfer this
heat and, if necessary, supply a cooling system or buffer cylinder.
Equipment level for operation to VDE 0108, comprising
• Batteries to VDE 0510 part 2
• Independent battery voltage monitor
• Key switch for test run
• Key switch for power failure simulation
• Incl. configuration expenditure
• Additional zero volt message contacts for parallel mains mode and emergency power mode
Note:
The standard emergency power mode (without equipment level to VDE 0108) is included in the Vitobloc
standard delivery.
