Danger!
Supply voltage!
There is the risk of an electric shock involving injury or death when coming into contact with non-insulated
components carrying supply voltage.
Measures:
• During electric installations, all regulations in force need to be adhered to (e.g. VDE 0100 / IEC 60364).
• Service measures must only be undertaken when the system is deactivated!
• All types of electrical work must be carried out by authorised and qualified personnel only.
• At an AC supply, a reliably accessible separator must be provided close-by (e.g. power plug or switch), which
separates all current-carrying conductors
• If the potential-free contact carries voltage that is dangerous in the case of contact, a corresponding separator
must also be provided.
• The provided 24 VDC voltage must meet the requirements for protective extra-low voltages (PELV) in accordance with IEC
60364-4-41.
Note:
Between terminals KL 1.1 and 1.3. of the VCD devices and housings or condensate connections, there is no galvanic isolation.
As regards tests, for example protective conductor tests in accordance with VDE 0701-0702 / IEC 85/361/CD, it must be ob-
served that there is only a connection for the establishment of a functional earthing between the touchable conductive parts
of the device and the protective conductor base, and no protective connection capable of carrying current.
Tighten the threaded cable connection with a slightly sealing effect.
Potential-free contact
Via the potential-free contact, the alarm signal can be transmitted (i.e. to a control system). The switch-over contact can be
operated in the fail-safe mode.
For example, if supply voltage is applied and if the BEKOMAT functions trouble-free, the alarm relay is activated. The normally-
open contact (0.7-0.8) is closed.
If no supply voltage is applied or if a trouble indication occurs, the alarm relay is released. The normally-open contact is open
(alarm).
External test button (optional)
With this button, accumulated condensate can be discharged systematically via remote control. Here, the normal test-button
function is additionally led out of the BEKOMAT. When the external contact is closed, the valve opens. Observe the additional
instructions!
Between the protective conductor/PE connection and the piping, a potential difference is not admissible. If required,
potential equalisation in accordance with VDE 0100 / IEC 60364 must be provided for.
