2. Safety instructions
Installation of the transmodulator must be done according IEC60728-11 and national safety standards.
Any repairs must be made by skilled personnel.
Do not expose this transmodulator to moisture or splashing water and make sure no objects filled with liquids, such as
vases, are placed near or on the unit.
Avoid placing the transmodulator next to heat sources such as central heating components or in areas of high humidity.
Keep the transmodulator away from naked flames.
If the transmodulator has been kept in cold conditions for a long time, bringing it into a warm environment may cause
condensation, so allow it to warm up for no less than 2 hours before plugging into the mains.
Ventilation should not be impeded by covering the transmodulator, such as newspapers, table-cloths, curtains etc.
Mount the transmodulator in a vertical position only. If installing in a 19” rack system additional forced air cooling fans
may be required (see table "Technical specifications" - operating temperature range).
Always allow 10 cm of free space from the top, front and bottom of the unit to enable any heat to be dissipated.
