• Do not exceed the specified operational temperatures and humidity range.
• Mount inside an electrical switchboard or control cabinet.
• Make sure there is sufficient air ventilation and clearance to other devices mounted
next to the unit.
• Observe applicable local regulations like EN60204 / VDE0113.
Powering the SERIP-100
Before connecting power please follow the rules in the section called "Safety Precau-
tions" and the section called "Before connecting anything".
Power is supplied via a 3.81 mm 2-pin pluggable terminal block located at the top side
of the mounted unit (refer to Figure 2.1, "Location of connectors" ). The following table
and picture shows the power terminal socket pinout:

Make sure that the polarity of the supply voltage is correct before connecting any
device to the serial ports! A wrong polarity can cause high currents on the ground
plane between the V- power supply pin and the serial port ground pins, which can
cause damage to the device.
Wiring the RS-485/RS-422 interface
The gateway's serial port can be configured by software to use the RS-485 or RS-422
physical layer. This is done through the web interface (See the section called "Configuring
serial port").
The RS-485 and RS-422 signals are located at the 3.81 mm 6-pin pluggable terminal
block on the top side of the mounted unit (refer to Figure 2.1, "Location of connectors" ).
