3.1.3.2. Cautions on Wired Control XK49 Replacement
To replace the wired control XK49, in addition to the preceding handling steps specific for XK46, you
should also configure access control.
(1) If the wired control does not need an access control system, set switch ā1ā for DIP S1 at the
bottom of the wired control to digital end (neglect switch ā2ā).
(2) If the wired control needs an access control system, set switch ā1ā for DIP S1 at the bottom of the
wired control to ON (neglect switch ā2ā) and connect the access control card interface to ports N and L or
ports VCC and GND of the wiring terminal. The following should be noted:
1) Ports N and L are power interfaces of 100-240V~50/60Hz access control.
2) Ports VCC and GND are power interfaces of DC 5-24V access control.
3) Either of them can be selected at one time.
