I NSTALLATION
This equipment is intended to only be installed by qualified service personnel.
The equipment shall be connected to a socket-outlet that provides a protec-
tive earthing connection.
North American
Requirement
CAUTION-To reduce the risk of fire, use only No. 26 AWG or larger telecom-
munication line cord.
M OUNTING THE EF2280
The EF2280 can be mounted in a rack enclosure using four large screws (10-
32x1/2”) included with the unit. One EF2280 fits in a single rack space.
Recommendation
For Easy Access
While not required, leave a single rack space in between the EF2280 and
other units in your rack. This gives you easier access to the back panel. If you
cannot leave a single rack space, mount the EF2280 below units that are lon-
ger in length so that you can access the Phoenix connectors on the back
panel more easily.
Instructions for
Securing Power
Supply to Back of
EF2280
• Locate the cable clamp on the back panel of the EF2280 above the RS-
232 port.
• Remove the screw and thread the power cord through the cable clamp.
• Attach the cable clamp to the back panel of the EF2280 and tighten the
screw. Align the clamp so that the power cable does not interfere with the
connectors on the EF2280 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 EF2280.
C ONNECTING THE EF2280 TO O THER E QUIPMENT
Grounding The EF2280 has 8 mic/line inputs plus 4 line level inputs and 12 line level out-
puts. 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 con-
nected to the input power ground.
Caution! Do not use any other power supply other than the one provided with
this unit.
