Please observe:
• VDE 0100
• The installation must comply with current IEC and national local regulations or
5
any particular regulations, specified by the local electricity supply company
• The rating plate and technical specifications

Structural prerequisites

• The appliance must be installed via a permanent connection. Heater must be
earthed!
5
• The electric wiring should not be injured. After mounting, the wiring must not be
direct accessible.
• An all­pole disconnecting device (e.g. via fuses) with a contact opening width of at
3
least 3 mm per pole should be provided at the installation end.
• To protect the appliance, a fuse element must be fitted with a tripping current com­
4
mensurate with the nominal current of the appliance.

Load shedding relay

If further three­phase appliances are connected, a load shedding relay designed for
electronic instantaneous water heaters (CLAGE no. 82250) can be connected to phase
conductor L .
2
To avoid possible jitter of the load shedding relay caused by low power consumption
(low temperature set point and low water flow rate) the "Load­shedding­mode" can be
activated as followed:
• Disconnect the appliance from the power supply (e.g. by switching of the fuses)
• Insert the jumper on the power electronics (see picture)
• Put the appliance into operation again
