6.1 Select power supply
The lock is designed for low power consumption. Only when the deadbolt is moved
does a larger current flow.
1. Select the power supply according to the maximum current consumption.
Note: If several locks are connected to one power supply at the same time, the
maximum current consumptions of the individual locks are added together.
WARNING
In the case of power supplies with high output power, there is a risk of fire due to
high currents in the event of a short circuit!
High currents can cause severe damage due to overheating and even fire.
• In the case of power supplies with high output power, protect the connection
lines to the individual locks with current limiters.
