Safety Instructions
III Planning and Installation - Rev. 0 / 04.2002
CAUTION!
To reduce the risk of electric shock, plug each power supply cord into sepa-
rate branch circuits employing separate service grounds.
When setting up and connecting the switcher, connect the external earth line al-
ways before connecting the power line.
Thus is ensured that in case of a short-circuit between mains and case, the voltage
is led to earth. For this reason,
never disconnect the earth line from the device while
it is operated.
The switcher must be only connected to an earthed socket. Check functioning of
the protective conductors. It must not be live. Any discontinuity in the protective
conductor may lead to a situation in which operational safety of the switcher can not
longer guaranteed. Earthing has to be performed according to the regional safety
regulations. When installing the lines, it is necessary to observe the national stan-
dards.
When mounting the mainframe and panel, care should be taken to allow for ade-
quate air circulation. Detailed information you can find in the respective sections in
the installation manual of the switcher. Keep the mainframe door always closed
during operation.
D
The admissible ambient temperature range of the mainframe is within
+5
° C and +35 ° C. Optimum operation is ensured at an ambient temperature
of 20 ° C.
D
The admissible ambient temperature range of the control panel is within
+5
° C and +30 ° C.
D
Make sure that the switcher is protected against humidity and keep dry!
The switchers are equipped with “Auto-Range” mains supplies and can be operate
in the following voltage ranges:
D
Control panels
voltage range of 100 V to 240 V ± 10 % AC
D
Mainframe
voltage range of 100 V to 240 V ± 10 % AC
Before connecting power to the switcher, make sure that the voltage adjustment in
the unit corresponds with the line voltage available in the studio.
CAUTION! - Double-pole or neutral fusing!
After acting of the protective devices, parts of the equipment may remain under
voltage. Each main input is is protected by two primary-side fuses located on the
power terminal of the switchers units (mainframe, panel). Additionally, the power
supply units will be protected by internal fuses.
When replacing the fuses, make sure that a fuse link of same type and same cur-
rent rating is used. Never use a mended fuse! Do not short-circuit the fuseholder!
Operate the switcher in the closed condition only, i.e. the mainframe with closed
door and locked panel. There are no parts inside the unit to be adjusted by the user
or parts to be exchanged.
