Installation and connection

It is important that you read these operating instructions, including the safety instruc-

tions thoroughly and carefully before rst use to ensure that you will launch the relay

board properly! If in doubt, let a specialist do the installation and connection.

Only connect boards when they are disconnected from voltage/current. Otherwise,

there is a risk of a life-threatening electric shock!

a) Installation

The relay board must be installed so that accidental contact is avoided. Here also a sufcient

distance to low voltage or non-mains-carrying circuit parts must be observed. Secure the board

so that it will not come loose.

Warning! There is a risk of a life-threatening electric shock if the work is done incor-

rectly!

b) Connection

• Two-pole connection terminal “IN”: Control voltage (230 V/AC, 50 Hz) connection for switch-

ing the relay contacts (connection phase/L and neutral conductor/N is not important)

When control voltage is applied, a control LED will go on next to the connection

terminals. You can route the LED light. to the front of an enclosure using suitable

light conductors, for example.

• Two three-pole connection terminals “CO/ NC/NO”: Relay switching contacts; two potential-

free switching contacts

CO = Common switching contact

NC = Switch output “normally closed” (closed when idle)

NO = Switch output “normally open” (open when idle)

Secure all cables carrying mains voltage appropriately. Ensure appropriate strain

relief of the mains cables dependent on the place where the relay board is installed.

Maintenance

The relay board is maintenance-free. However, check the connection leads for damage from

time to time and that the connections are mechanically secured.

Only an authorised expert may perform repairs.

Before you start working on the module, disconnect the mains cable from voltage/

current; the same also applies to all devices connected to the relay contacts.

Disposal

Electronic devices are recyclable material and do not belong in the household

waste. Dispose of an unserviceable product in accordance with the relevant statu-

tory regulations.
