PLM+ SERIES
Cooling and fan operation
PLM+ devices use a forced-air cooling system with air ow from front to rear, allowing high continuous power levels without thermal problems. To facilitate maximum
air ow, ensure that no objects such as rack doors or lids are placed at the front or rear of the rack. Never attempt to reverse the air ow. Make sure an adequate air
supply is provided in front of the PLM+ device, and that the rear of the device has su cient space to allow air to escape. It is recommended to keep the ambient
temperature around the device as cool as possible. An increased temperature can have a signi cant negative impact on the expected lifetime on the components
inside the PLM+ Series device.
Note: Fit solid blanks (not ventilation blanks) to unused rack spaces to ensure e ective air circulation. Leaving gaps in between items of equipment degrades the
e ectiveness of forced-air cooling.
If installing one or more PLM+ devices in a rack with other fan-cooled equipment, con rm that all other equipment also uses front-to-rear air ow for cooling.
If this precaution is not observed, there is a risk of overheating, as units with the reverse air ow will be drawing in air which has already been heated by the
PLM+ Series devices.
The PLM+ device is equipped with a sophisticated temperature sensing system which protects it from any overheating which may occur as a result of
inadequate ventilation.
Operating voltage
PLM+ Series has a universal power supply and its mains nominal voltage is 100 – 240 V. The PLM+ series can be ordered with a variety of mains plugs suitable for
di erent territories.
Note: In-rush current is controlled and limited during the soft-start sequence. This enables multiple PLM+ Series Devices on the same AC mains circuit
to be turned on simultaneously.
Grounding
Use correctly-shielded balanced audio input connections to minimize hum and interference.
PLM+ Series must be grounded (earthed) with the safety ground pin to the mains distribution system.
NEVER disconnect the earth (ground) pin on the mains cable (AC power cord).

(1) Handles – Handles should be used when carrying, and when tting into or removing from a rack. Ensure that rack doors or covers have su cient depth to clear
the handles.
(2) Dust Filters – Two dust lters are located behind metal covers. Loosen thumbscrews behind the handles to remove covers and
remove lter elements for cleaning.
Note: NEVER operate this device without the dust lters in place.
(3) Display – The display illuminates when device is on. Brightness and contrast can be adjusted via the front panel menu. A Screen Saver function turns o the
display after 30 minutes of no activity. Press any button to turn on the display.
(4) Standby – Switches device between On and Standby power modes.
