ORTEX
This equipment is intended to only be installed by qualified service personnel. The
equipment shall be connected to a socket-outlet that provides a protective earthing
connection.
CAUTION-To reduce the risk of fire, use only No. 26 AWG or larger telecommunica-
tion line cord.
The EF2241 can be mounted in a rack enclosure using four large screws (10-32x1/2")
included with the unit. One EF2241 fits in a single rack space.
While not required, leave a single rack space in between the EF2241 and other units
in your rack. This gives you easier access to the back panel.
• Locate the cable clamp on the back panel of the EF2241 above the power con-
nector.
• Remove the screw and thread the power cord through the cable clamp.
• Attach the cable clamp to the back panel of the EF2241 and tighten the screw.
Align the clamp so that the power cable does not interfere with the connectors on
the EF2241 back panel.
• Plug in the power supply.
• We recommend that you also Ty-wrap the power supply to the rack. The purpose
of securing the power supply to the back panel is so that if the power supply were
to drop, it would pull where the cord is attached with the cable clamp and not pull
the plug out of the EF2241.
Caution! Do not use any other power supply other than the one pro-
vided with this unit.
EF2241 O
TO THER
The EF2241 has 4 mic/line inputs plus 4 line level inputs and 8 line level outputs.
Each input/output is "Pin 1 compatible" — this means that the ground pin of each
input/output is tied to chassis ground. Chassis ground is connected to the input power
ground.
