4.1 Power supply
The power supply is performed via connector X1, terminal 1 and 2 (see chapter 4. Reader
connection ). The device may be supplied either with 12 - 24 V AC / DC. The polarity of DC supply
can be selected freely.
NOTE:
The length of the wire between mains receiver and megalock Infoterminal should be as
small as possible and it should not be positioned directly parallel to other power supply- or
low voltage lines.
4.2 Digital inputs (IN1 / IN2)
Both digital inputs (connector X2 [IN1] respectively [IN2], see chapter 4. Reader connection have
to be switched only opposite [GND] to connector X2. A supply with external voltage may cause the
damage of the device.

4.3 Relay
The device is provided with an electronical semiconductor relay. The connecting is performed at
connector X2, terminal [COM] and [NO].
The relay is protected against overcharge by means of a miniature fuse (see: Fig. 1: Position of
the connecting terminals and the operational control , "Fuse").
