Installation

Unpacking
Carefully open the shipping carton and check for any damage to the device or the supplied accessories. Every Lab.gruppen productis tested and inspected before leaving the factory and should arrive in perfect condition. If any damage is discovered, please notify the shipping company immediately. Only the consignee may initiate a daim with the carrier or their insurers for damage incurred during shipping. Save the carton and packing materials for the carrier’s inspection.

Included in the box
In addition to the PLM+ device, the shipping carton includes the following items:

• PLM+ Quick Start Guide (this Document)
• ACmains lead (power cable) with Neutrik® powerCON® connector (PLM 20K44, 12K44 and 8K44 only) and AC socket plug according to ordering selection. PLM 5K44 uses a locking IEC connector.
• Rearbrackets for additional rack support (pair) along with associated mounting hardware. Please keep the original carton and associated packaging to facilitate shipping of the device should the need arise.

Mounting
PLM+ is made for mounting in 19 inch racks. Four screw holes are available for attachment of the amplifier to the racks front rack rail. This device has no top or bottom vents; therefore, units may be stacked directly on top of one another. Sufficient space should be available at the rear to accommodate connectors and cables. In addition, allowance must be made for cable or loom bends within a rack.

Rear Mounting
Tworear support brackets, along with associated mounting hardware, areincluded with the PLM+ device. It is strongly recommended that these are used wherever possible. Fit the brackets to the vertical rails at the rear of the rack. The support brackets are reversible and may be fitted to point either to the front or rear of the rack; the proper orientation depends on the rack depth and position of the rear rack rails

Cooling and fan operation

PLM-+ devices use a forced-air cooling system with airflow from front to rear, allowing high continuous power levels without thermal problems. To facilitate maximum air flow, 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 airflow. Make sure an adequate air supply is provided in front of the PLM-+ device, and that the rear of the device has sufficient space to allow air to escape. Itis recommended to keep the ambient temperature around the device as ool as possible. An increased temperature can have a significant 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 effective air circulation. Leaving gaps in betweenitems of equipment degrades the effectiveness of forced-air cooling. [finstalling one or more PLM+ devices in a rack with other fan-cooled equipment, confirm that all other equipment also uses front-to-rear aiflow for cooling.

If this precaution s not observed, there is a risk of overheating, as units with the reverse airflow will be drawing in air which has already been heated by the PLM+Series devices.

The PLM+ device is equipped witha sophisticated temperature sensing system which protects it from any overheating which may occuras a result of inadequate ventilation.

Operating voltage
PLM-+Series has a universal power supply and its mains nominal voltage is 100 — 240V. The PLM+ series can be ordered with a variety of mains plugs suitable for different territories.

Note: In-rush currentis 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).
