Design

View

The OPA 8500 is built as a 1 HU 19" slide-in module.
The front-panel contains:

l

the display

l

the LED’s

l

the operating elements

l

two RF monitoring outputs

The rear-panel contains:

l

2 x mains connection

l

10 x RF input

l

RF output

l

RS232 interface

l

10 Mbit Ethernet-interface

l

Remote monitoring interface ”ALARMS”

Cooling

The SAI 8500 is cooled by convection.

Power supply

The OPA 8500 can be operated with the following mains voltages:

l

115 VAC

l

230 VAC

The power supply is of redundant design. For back-up purposes there are two mains
connectors available on the rear-panel. The OPA 8500 can be integrated into a back-up
supply system.

ATTENTION:

Before operation make sure that the mains voltage matches the
supply voltage indicated on the device.

The mains fuse is located beside the mains socket. The OPA 8500 does not have a
mains switch. To disconnect the OPA 8500 from the mains, both mains plugs must be
pulled out of the device. Both mains voltages (mains 1, mains 2) can be monitored
through alarm messages.
