SAFETY INSTRUCTIONS
The DD switcher is designed in conformity with the safety regulations EN60950 /
VDE 0805 (protection class 1) and are in an unobjectionable condition when leav-
ing the factory.
Information on the following pages provides important safety guidelines for Opera-
tors and Service Personnel. Specific warnings and cautions will be found through-
out the manual where they apply, but may not appear here. Please read and follow
the important safety information, noting especially those instructions related to risk
of fire, electrical shock or injury to person.
Warning:
Any instructions in this manual that require opening the equipment cover or
enclosure are for use by qualified service personnel only. To reduce the risk
of electric shock, do not perform any servicing other than contained in the
manual unless you are qualified to do so.
With the standard modules installed, the E Box and panels are heavy. During instal-
lation and until secured in the rack or the desk, use an appropriate lifing device to lift
and support the mainframe. Failure to follow this precaution can result in injury to
personnel and damage to equipment.
The equipment shall be installed in Restricted Access Areas.
The switcher is designed for operation with one-phase mains earthed neutral con-
ductor. When setting up and connecting the switcher, connect the external earth
line always 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 switcher EBox and panel, care should be taken to allow for ad-
equate air circulation. Detailed information you can find in the respective sections in
the installation manual of the switchers. Keep the EBox door always closed during
operation.
The admissible ambient temperature range of the switcher is within
+5
°
C and +35
°
C. Optimum operation is ensured at an ambient temperature of
25
°
C
±
5
°
C.
Make sure that the switcher is protected against humidity and keep dry!
Depending on the order of the customer, the switcher is adjusted to operate on
115V or 230V. The respective adjustment is indicated on the connector panel of the
unit. Before connecting power to the switcher, make sure that the voltage adjust-
ment in the unit corresponds with the line voltage available in the studio.
Switching-over to another line voltage has to be carried out by qualified ser-
vice personnel.
