Technical Description
The cabinet can be equipped with an optional heater, including a thermostat,
for operation in cold environments. The heater is power supplied by -48 V DC.
The bottom of the cabinet holds 12 cable bushings where DC and traffic cables
can be feed. The bottom also holds five adapters for radio cable connection.
A fan alarm can be used to detect cooling system malfunction. Furthermore,
a door sensor is mounted in the cabinet, which can be used to generate an
alarm when the lockable door is opened.
The TMR 9302 is power supplied by -48 V DC, from an external DC supply
source or an optional dedicated AC/DC converter (PSU). The PSU converts
100-250 V AC to -48 V DC, see Figure 103 on page 133. The maximum
output power is 420 W. The PSU fulfills Over Voltage Category II, according
to IEC60950.
The PSU supports the same mounting alternatives as the TMR 9302.
