6. INSTALLATION AND CONNECTION
6.1 LOCK AND LATCH MOUNTING
1. Install the latch in the area designed for installation.
2. Insert the latch into the lock and fix the lock so that the latch enters it until click.
3. Connect the lock (see cl. 6.2) and function test by applying supply voltage. The lock must
unlock the latch. Open the door so that the latch disengages with the lock.
4. If the latch is not unlocked when power is supplied, push the door in the area of lock fixation
and apply voltage. Then adjust the latch length providing for the necessary free play and
alignment.
6.2 CONNECTING PROCEDURE
The lock operation is controlled by supplying and blocking power. For this purpose a controller
(control board) or a switch (button) is generally used. The controller is mounted in accordance
with its certificate.
Connect the lock power wires adhering to the following polarity:
