User manual FURMAN PL8

[. . . ] If the total load on the PL-8 (combining all outlets) exceeds 15 amps, the circuit breaker will trip, cutting off power to your rack. If this occurs, reduce the load by unplugging one or more units from the PL-8. Then push the black button on the circuit breaker (on the front panel) down and in to reset it. The PL-8's lamps come supplied with five-watt night-light bulbs. [. . . ] This filter is a low-pass type, composed of high-voltage capacitors and an inductor. It passes the low (50 or 60 Hz) line frequency while rejecting high frequencies, with maximum attenuation in the region from 1 to 100 MHz. The PL-PLUS' voltmeter has a basic accuracy of +/- 2 volts, (extreme cold or heat may cause an additional one volt of error). Should the voltage reading ever become inaccurate, it can be easily recalibrated by a qualified service technician. Circuit Breaker Dimmer Switch Rack Lights Power Switch 3 8 Switched Outlets PL-8/PL-PLUS POWER CONDITIONER offer depends on the intensity of the strike. If lightning strikes a distant power line and causes a relatively small disturbance to reach your location, the spike suppressors in the PL unit will absorb the excess voltage invisibly and harmlessly. However, if lightning strikes the actual building where the PL unit is installed (or somewhere nearby), some damage may be unavoidable due to the extremely high voltage and current present. If this does occur, the 220/240 VOLT VERSIONS damage, most likely, will be limited to the PL unit itself and will affect only the ("E" SUFFIX) spike suppression components (called Versions of the PL-8 and PL-PLUS varistors or MOV's. ) In this "suicide" with the "E" suffix are intended for use mode, the PL unit will sustain minor in countries with nominal 220 to 240 damage to itself. These units have 10 rear will protect all equipment plugged into panel outlets, using the internationally it from much more serious and costly accepted IEC-320 connectors, and are damage as long as that equipment is rated at 10 amps. Proper grounding PL-PLUS E reads from 180 to 256 volts requires the use of three-prong AC AC. cords and that the outlets themselves are actually grounded (as specified by electrical codes). EFFECTS OF LIGHTNING AND Any PL unit known to have taken a INCORRECT VOLTAGES direct lightning hit should be checked Lightning presents the most difficult by a qualified technician or Furman circumstance faced by power factory staff to determine whether the protection products. (If they are protection a PL-8 or PL-PLUS unit can damaged, the PL unit may appear Please note that the voltage reading is advisory only. The PL-PLUS does not compensate for high or low line voltage. If you frequently move your rack to different locations, derive power from generators, use long extension cords, travel internationally or are in an area prone to brownouts, you may benefit from the use of one of Furman's AR Series AC Line Voltage Regulators. 4 PL-8/PL-PLUS POWER CONDITIONER to be working normally, but its vital spike-suppression capability will be eliminated. ) You should not rely exclusively on the PL unit for optimum protection against a direct lightning hit. The first line of defense against lightning should be a lightning arrestor installed on your building's electrical service entrance. If your building does not have one, contact your local power company or an electrical contractor to have one installed. The PL-8 and PL-PLUS are not intended to protect against accidental connection to an improper voltage supply (such as 220 Volts in North America or 380 Volts in other areas. ) If such a connection is made, the PL unit's MOVs will most likely be destroyed, which may or may not provide sufficient time for its circuit breaker to trip. If it does not trip in time, it is possible for equipment downstream to be damaged. In our experience, such accidents happen surprisingly often. For complete protection against this possibility, a more sophisticated protection device is needed, such as a Furman PRO Series Power Conditioner, AR Series AC Line Voltage Regulators, or Furman's SMP products. 5 DEFINITIONS SPIKE: This is a pulse of energy on the power line. Spikes can have voltages as high as 6000 volts. [. . . ] repairs done by other than the Furman factory or Authorized Repair Stations.
