PLM+ SERIES Quick Start Guide rev 3.0.4
8. 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.
9. Operating voltage
PLM+ Series has a universal power supply and its mains nominal and operating voltages are specied in the
Technical Specications (see section 15). PLM+ Series can be ordered with a variety of mains plugs. If the mains
plug (AC plug) tted to the mains cable (AC cord) is not appropriate for your country it can be removed and a
locally-sourced one tted instead. If you are not 100% condent of your competence to replace the mains plug (AC
plug), the task should be carried out by qualied personnel.
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.
