13. ELECTRICAL CONNECTION

13.1 GENERAL INSTRUCTIONS

a) The electrical connection must always be implemented in accordance with the circuit diagram
pasted in to the connection space of the storage tank!
b) Ensure the correct connection voltage!
c) An all-pole isolation switch with a contact opening width of 3 mm is to be provided in the
electrical supply line. Automatic circuit breakers are also permissible as isolators.
d) The connection cable must be inserted into the connection space of the storage tank and be
prevented from being pulled out and twisted by a strain relief mechanism. For register storage
heaters a second cable insert is provided for the charging pump control cable.
e) For installation and intrusive interventions into the device, the hot water storage tank must first
be isolated completely (all poles) and on every side from the power supply in compliance with EN
50110 (ÖVE, TAEV).
Before carrying out any further work, the system must be secured against the accidental
reconnection of the power supply (remove the fuses, trigger the mains circuit breaker).

13.2 RECONNECTION OPTIONS

In the case of storage
heating rods is to be carried out in accordance with the circuit diagram pasted
to the device. Switching
6-hour heating time in ~ 230 V connection voltage. The polyphase circuits from 100 litres upwards, 3
~ 400 V and 3 N ~ 400 V, are also to be connected in accordance with the following table.
Reconnectable heating times and outputs at associated protection currents 16A.
