Site Requirements
Power Supply
Ensure that the correct power supply is available for powering the terminal.
The nominal input voltage for a terminal is 12, 24 or 48 volts DC or 115 / 230 volts AC rms.
The DC supply voltage is factory preset at time of order and cannot be adjusted in the field.
The terminal voltage is indicated on the chassis label by the DC input connector and on the specification
label fitted to the terminal.
WARNING:
Before connecting power, ground the chassis using the safety earth terminal on the
front panel.
Equipment Cooling
Mount the terminal so that air can flow through it. Do not obstruct the free flow of air around the
terminal. The two internal, speed-controlled fans fitted into the chassis provide sufficient cooling.
The operation of the fans is monitored and an alarm is raised under failure conditions.
The environmental operating conditions are as follows:
Operating temperature
-10°C to +50°C
Storage temperature
-20°C to +70°C
Humidity
Maximum 95% non-condensing
