INTO OPERATION
MAINS CONNECTION
Install the SZI 1029 high power radiator in a vertical (or almost vertical)
position. The cables are guided downwards.
The vertical position ensures sufficient cooling of the radiator - air can
circulate through the cooling fins that are integrated into the sides of the
radiator.
The SZI 1029 high power radiator is provided with an interchangeable
thread for mounting it to stands with 3/8" or 1/2 „threads using an adaptor
(included in the scope of delivery).
CONNECTING AN IR RADIATOR After having connected the radiator to the mains, the IR input of the
SZI 1029 has to be connected to the IR output of the modulator.
Several co-axial cables are available for this purpose (see ELECTRICAL
ACCESSORIES). The cables can be connected to one another using a
BNC coupler GZV 1019 A.
IR output BNC for extension radiators
For permanently installed systems you should use commercially available
50 Ω coaxial cables, such as RG 58 (75 Ω cables can be used if 50 Ω
cables are unavailable). If you want to use several SZI 1029 radiators
you have to connect them in series. This is done by connecting the output
BNC socket of the first radiator with the IR input BNC socket of the
second radiator. A maximum of 100 radiators can be connected in series.
The maximum total length of the cable should not exceed 1500 m.
After having connected the last radiator you can put the transmission
system into operation by switching on the modulator. It transmits a carrier
signal which automatically switches on the radiators. When the carrier
signal stops, the radiators switch off automatically.
N.B.: In order to avoid standing waves a terminating impedance of 50 Ω
should be connected to the last radiator (or 75 Ω terminating impedance
if 75 Ω cable was used).
