The AMPS-24 mounts in the lower left of a CAB-4 Series enclosure.
!
WARNING: High Voltages Present!
Use extreme caution when working with the AMPS-24. High voltage and AC line-connected circuits are
present in this power supply. Turn off and remove all power sources. To reduce the risk of electric shock,
make sure to properly ground the AMPS-24.
Install the snap-on cover for TB1 after wiring.
NOTE:
A surge suppressor, model EDCO HSP121BT-1RU (for 120VAC operations) is required when using the
FCM-1-REL for releasing applications. The AMPS-24E power supply is not suitable for releasing applications.
NOTE:
Test wire to wire faults with 0 ohm impedance.
!
WARNING: Risk of equipment damage!
Due to heat dissipation, total battery capacity must not exceed 26 amp-hours when the AMPS-24 is
charging in a CAB-4 series cabinet. Refer to the Heat Dissipation PID to determine the acceptable
heat dissipation in the cabinets when digital audio products are present.
Figure 2.1 CAB-4 Series Backbox
Install the AMPS-24 in the lower
left of any CAB-4 Series cabinet.
Lower the power supply over the
cabinet’s support brackets and
fasten to the backbox with two
self-threading #6-32 screws, at the
indicated positions.
The AMPS-24 may also be
installed in a CHS-6 chassis in a
CAB-4 Series cabinet. (Refer to
Figure 2.2 on page 15.)
