Mounting cable relief bracket and covers
To secure heavy duty cables at the relay receptacles a cable relief
bracket and cover are supplied with the ALFA II.
Secure the cable relief bracket to the ALFA II with the supplied
M4x6mm screws. Insert your cable in the supplied screw terminal
connector and insert this connector into the ppropriate relay recep-
tacle in the ALFA II.
Secure the cables to the cable relief bracket with supplied cable
binders.
Finally, mount the cable relief cover over the cable relief bracket and
secure with supplied M4x45mm screw.
CONNECTIONS AND CONTROLS
AC Line
Connect the ALFA II to the AC line supply using the supplied power
cable. The cable will be equipped with a line socket connector for
use in the country of sale.
The ALFA II incorporates a universal mains power supply which ac-
cepts AC line input from 100 V to 240 V.
Relays
Relays allow the option of NO (Normal Open) and the NC (Normal
Close) for greatest flexibility. An LED for each relay is located on the
front panel. When the LED illuminates green, it indicates the COM is
connected to NO.
You can connect cables directly to the ALFA II using the supplied
terminal block connectors for each relay. Use the supplied cable
relief brackets to fix the cables with a cable tie to prevent acciden-
tal disconnection of the cables. (See section Mounting cable relief
bracket and covers on page 6.)
If you want to connect and conveniently switch AC power for exter-
nal equipment, install the Biamp IEC Mains Adaptor (306-0015, sold
separately) instead of the terminal block and cable relief brackets.
