Power supply
7.1 SIDOOR NT40
The rated data of the output are:
Rated output voltage
Rated output current
Continuous output power rating
Dangerous electrical voltage.
May cause death, serious injury or property damage.
The third line brought out at the output is only a functional grounding connection, this must
not be regarded or used as a ground in the sense of a PE connection!
Connection specifications
Dangerous electrical voltage!
When operating electrical devices, certain parts of these devices are necessarily under
dangerous voltage. Failure to observe the operating instructions can therefore result in serious
injury or material damage.
Observe the operating instructions.
Observe the following connection regulation:
• The regulations for the construction of high voltage installations must be observed when
carrying out the electrical installation.
• The switch mode power supply may only be connected to the power supply by connected
supply lines.
• The power supply (230 V AC ± 15%) must be connected according to VDE 0100 and VDE
0160.
• The supply voltage to the device must be equipped with a protective device (automatic circuit
breaker) (10 A / tripping characteristic B).
• The protective conductor is connected via the supply line X1.
• Output lines may only to be connected to the SIDOOR control device.
• When connecting the device to the power system, it must be ensured that this network
fulfils the requirements for the overvoltage category II. If required, an external overvoltage
protection is to be connected upstream of the device so that the requirements for the
overvoltage category II are fulfilled.
• Ensure that the power outlet is clearly recognizable and easily accessible.
