4.2.7. Environmental conditions
The equipment conforms to the environmental classes defined in ETS-300-019:
• Transportation: ETSI-EN-300-019-1-2, class 2.3, public transportation.
(temperature range: -40
°
C to +70
°
C).
• Storage: ETSI-EN-300-019-1-1, class 1.2, weather protected,
not temperature-controlled storage locations.
(temperature range: -40

According to ETSI-EN-300-019-1-4, class 4.1 , non weather
protected locations
For temperatures below 0
°
C the equipment must be switched on
for at least 10 minutes in order to operate according to the
specifications.
4.3. Mechanical Characteristics
4.3.1. Installation
The equipment is very easy and quick to install. It is designed for stationary use in split mount
installations. IFU and ODU are interconnected with coaxial cable. One cable for each ODU is used. (i.e.
Two cables needed for HSB, 1+1 FD and 2+0 systems). The IFU can be installed as a stand-alone unit,
or it can be mounted in a standard 19“ rack (Ref. IEC 297-2 and IEC 297-3), or in an ETSI standard
cabinet (Ref. ETSI EN 300 119). The ODU
1
may be mounted directly to the antenna for antenna sizes up
to and including 1.8 m. Alternatively the ODU can be supplied with a mount for a vertical column (Ø=60-
115mm).
