ABOUT THE MINIPORT-30
The Furman MINIPORT-30 Power Relay is a 30 amp, contact or
switched 120 VAC outlet, with a terminal strip that allows remote
control via safe, inexpensive, low voltage Class 2 wiring.
The MINIPORT-30 (NRTLC pending) provides a twist lock inlet and
outlet, and is housed in a heavy duty steel, 8” x 8” x 4” junction
box.
Like all Furman MINIPORTS, this model includes an internal 12
VDC supply, and can be controlled from a remote location by using
the Furman PowerLink Remote AC Power Sequence Controller,
the ASD-120 Sequenced Power Distro, or for simpler jobs, the
Furman RS-1 or RS-2 Remote System Control panels. The RS-
1 provides a maintained key switch; the RS-2 has a momentary
switch. (Please see the Furman data sheet “Remote Control
Products” for more detailed information.)
Multiple MINIPORTs may have their control wiring paralleled so
that all are controlled by a single switch closure, and may be linked
so that all turn on simultaneously or one by one, in a delayed
sequence. (Turning-off always occurs simultaneously.) This is
further explained in “Linking Multiple Units,” on overleaf.

MOMENTARY VS. MAINTAINED
CONTACT SWITCHING
An on-off switch of either kind may be used to actuate the MiniPort-30. Maintained
switches, such as most toggle switches, push-on/push-off button switches stay open
until the switch is engaged, and stay closed until the switch is disengaged. Momentary
switches, usually push-button types, are normally open and stay closed only as long as
the button is pressed.
Maintained switches are most convenient when there is only one remote switch location;
momentary switches allow turn-on or turn-off from multiple locations.
MiniPorts come factory-congured for maintained operation. They may be easily
converted to momentary operation by moving a jumper on the MiniPort’s circuit
board. To do this, rst disconnect the unit from AC power. Remove the four screws
that secure the cover. On the circuit board, there are two pairs of terminals, one
labeled “MAINTAINED” and the other “MOMENTARY.” There is a small black jumper
linking the MAINTAINED terminals. Slide it up and off, and replace it securely over
the MOMENTARY terminals. Reattach the cover.
