User manual FURMAN MP30

[. . . ] MiniPorts come factory-configured for maintained operation. They may be easily converted to momentary operation by moving a jumper on the MiniPort's circuit board. To do this, first disconnect the unit from AC power. Remove the four screws that secure the cover. [. . . ] This resets all units to the OFF condition, and avoids having to disconnect AC power from all units. LINKING MULTIPLE UNITS Multiple MiniPorts may be connected together so that all are controlled by a single switch closure. All the units must be set to the same mode depending on the type of switch or switches to be used (use momentary mode and momentary switches if more than one switch is required. ) All the units must be paralleled by tying together all the +12V terminals (see Wiring Diagram, below). Multiple MiniPorts may be linked so that they all turn on simultaneously, as discussed above, only the turn-ons are delayed (all turn-offs occur simultaneously. ) This feature is particularly MP-30 MINIPORT AC POWER RELAY useful in staggering the turn-on of large power amps to avoid large inrush currents that might trip the house circuit breakers. The delay interval is approximately two to three seconds (the first unit turns on with the switch closure, the second in the chain about 3 seconds later, the third unit 3 seconds after the second, etc. ) The choice of delayed or simultaneous linking is available regardless of whether maintained or momentary switching is used. However, if delayed linking is used with momentary switching, only the first MiniPort should be connected in parallel between the first unit's +12V and REM terminals. The second and subsequent MiniPorts must be left in maintained mode. With the addition of a Furman PS-REL AC Relay to provide control, a MiniPort can be used to extend the capacity of any other product that has a switched outlet, such as a receiver/ amp that is then controlled with a wireless remote. When used in this manner, the MiniPort is switched on or off when the outlet that the PS-REL is plugged into goes on or off. OPTIONAL REMOTE LED INDICATOR The MiniPort terminal labeled STATUS is an output that may be used to illuminate an LED at a remote location to indicate that power is available at the MiniPort's outlets. If it is HIGH (+12V relative to the GND terminal), the unit is ON; if LOW, the unit is OFF. Simply connect the indicator LED between STATUS and GND (do not use a series resistor). If multiple units are used, a separate LED must be used to indicate the status of each. Do not connect the STATUS terminals of multiple units together. MP-30 MINIPORT AC POWER RELAY KNOCKOUT HOLES All four sides of the MiniPort-30 enclosure have multiple knockouts to accommodate every installation, with 3/4" conduit ­ one on the top surface, the other on the bottom. According to the National Electrical Code, 3/4" conduit can accommodate up to five 20 amp circuits using ten THWN 12 gauge stranded wires; however, local codes should be checked for exact requirements. For grounding and other details, please consult a licensed electrician. THREE YEAR LIMITED WARRANTY The Furman MP-30 is protected by a limited three year warranty, covering defects in materials and workmanship, provided that the registration card is filled out and returned by the customer. Products must have a proof of purchase from a Furman authorized dealer. During this period, Furman will make any necessary repairs without charge for parts or labor. Shipping charges to the factory or repair station must be prepaid by the owner; return-shipping charges (via UPS Ground) will be paid by Furman. This warranty applies only to the original owner and is not transferable. Also, it does not apply to repairs done other than by the Furman factory or Authorized Repair Stations. This warranty may be cancelled by Furman at its sole discretion if the MP-30 unit has been subjected to physical abuse or has been modified in any way without written authorization from Furman. Furman's liability under the warranty is limited to repair or replacement of the defective unit. Furman will not be responsible for incidental or consequential damages resulting from the use or misuse of its products. [. . . ] Use of the bottom knockout hole requires removing the AC cord. According to the National Electrical Code, 1/2" conduit can accommodate up to five 20 amp circuits using ten THWN 12 gauge stranded wires; however, local codes should be checked for exact requirements. The MiniPort-15 is fused; the MiniPort-20 is equipped with a precision magnetic circuit breaker. Both are housed in rugged steel enclosures and come equipped with a heavy duty, 10 foot AC cord.
