Note!
If both external power input and battery power exist at the same time,
that external power will have high priority of main power source.
Note!
ADAM-2510Z router and ADAM-2520Z gateway are always in normal
transmission mode during operation, and which power consumption will
be higher than other end devices to shorten battery life, therefore, sug-
gest ADAM-2510Z and ADAM-2520Z adopt external power input for
main power source and battery power for backup power source.

I/O Module Wiring
The system uses a plug-in screw terminal block as the interface between I/O mod-
ules and external devices. When connecting external devices to the I/O modules, fol-
lows the guideline below.
1.
The maximum wire diameter allowed for the terminal block is 0.5 mm to 2.5 mm.
2.
Always use an integrity wire.
3.
Keep wires as short as possible.
4.
Use wire trays or wire holders to secure wires.
5.
Avoid running wires close to high energy wiring.
6.
Keep input wiring and output wiring apart.
7.
Avoid any sharp bend to the wires.
8.
Follow the (+) and (-) symbols on the side panel to wire correctly.

Communication Wiring
In a WPAN, only the Gateway needs to connect to a host. The ADAM-2520Z is the
Wireless Sensor Network Modbus RTU Gateway of the ADAM-2000 series and pro-
vides RS-422/485 and USB interfaces to connect to host. Users can choose one of
the interfaces by pushing the switch to RS-422/485 or USB position.
