Safety and installation notes

Caution
The mains voltage must match the rated input voltage of the unit (230 VAC).
CAUTION GROUNDING!!
Chassis must be grounded and disconnected from line power before any RF connections are made. Improper grounding may result in irreversible damage of the equipment.
Connecting cable
- Lay the cable so that no-one can trip over it.
- Lay the cable with a downward loop so that any water condensing on it can drip on the floor instead of running into the unit.
  Selecting the installation location
Excessive temperatures will reduce the operating lifetime of the unit. Don’t install the unit directly above or in the vicinity of radiators or heating systems where it would be subjected to thermal radiation or oil vapours.
Moisture Water dripping or splashing onto the unit will damage it. If there is condensation on the unit, wait until this has evaporated before switching the unit on.
Caution – danger! In accordance with EN 60728-1, the satellite antenna system must comply with the safety requirements with respect to grounding, potential equalisation, etc.
Service work Service work may be carried out only by qualified personal. Always disconnect the supply voltage before starting any such work.
Ambient temperature – Not greater than 50 °C.
Thunderstorms Avoid carrying out service work on the antenna system during thunder-storms.
Caution – danger! Fuses may be replaced only by qualified personnel. Only fuses of the same type and rating may be used.

Wall Mounting/ Hole Distances

For wall mounting of the OH50 chassis please use the supplied angle brackets, and fix it at both sides (see drawing). Use only the supplied screws (M4x6).

Wall Mounting versions

If the cables are fed from above the basic unit choose this wall mounting version.
If the cables are fed from below the basic unit choose this wall mounting version to maintain the min. bending radius of the coaxial cable.

Dust protection cover

To protect the basic unit during the mounting process from dust, please leave the carton as a cover at the front of the housing.

Assembly 19“-Rack

For 19”- mounting of the OH50 chassis please use the supplied angle brackets, and fix it at both sides (see drawing). Use only the supplied screws (M4x6).

Mounting 19″ angle brackets

Standard mounting (use front holes of the brackets)
Mounting for a bigger bending radius of the connection cables (use rear holes of the brackets)
Recommendation For operation all slots need to be equipped with a module, or covered with a blanking plate. Modules with a CI-slot need to carry the supplied covers, even without CA-module. This is necessary to assure proper air flow for cooling.
