1 Cable grip
Insert the connector of the plug-in mains unit into socket
the cable through the cable grip as shown. Because of the cable grip, the connector cannot slip
out of the socket and interrupt operation.
Note
A cable grip is particularly important when the device is permanently rack mounted.
Inside the rack there are often a large number of cables – a cable grip prevents the
cables from pulling each other out.

Rack mounting

The SI 1015 can be rack mounted into 1 U of a 19" rack by using accessories GA 1031-AM or
GA 1031-CC. The GA 1031-CC is a blank module to bring the SI 1015 to full 19" width, the
GA 1031-AM is identical but has additional BNC sockets to bring outputs
panel. The rack mountings are supplied with the SI 1015.
3 Connecting the SZI 1015 radiators
¸
Sockets and on the SI 1015 modulator can be used to connect two SZI 1015 power radiators.
For connecting the radiators, use ready made up co-axial cables with BNC connectors.
You can also use a co-axial cable without a connector. The cable has to be inserted into contacts
and of the barrier strip. Remove approx. 20 mm of the cable's cuter jacket, twist the screen into
a little roll, and pull it to one side. Strip the central wire by approx. 10 mm. Insert the screen into
the ground terminal and the central wire into the indicated contact on the barrier strip.
4 Daisy-chaining the radiators
Two SZI 1015 power radiators or one SZI 1029-24 high power radiator can be 25-29 V DC
powered by the NT 1015 plug-in mains unit via the SI 1015 modulator. The supply voltage is
output via the two contact pairs ¸+¹. Connect the radiators to the contacts by using a two-wire
cable with a cross section of 1.5 mm 2 per wire.
