IQ SERIES OWNERS MANUAL - 17 -
2.13 (13) AUTOMATIC POWER TRANSFER SWITCH
IQC Models only
The Automatic Power Transfer Switch is furnished only on IQC Models and consists of a circuit board
containing two relays. (IQ Models do not have the transfer switch but instead have a terminal strip in this
location.) See Automatic Power Transfer Switch Theory of Operation for performance details.
2.14 (14) AUTOMATIC THROTTLE CONTROL TERMINAL J31
All Models
Terminal J31 is provided to be used on utility vehicles where the inverter needs to operate continuous
heavy AC loads and the vehicle is equipped with an Automatic Throttle. Use J31 to turn ON the Auto
Throttle to insure that the vehicle alternator is producing maximum output whenever the inverter is
powering a load.
J31 is controlled by the Load Demand circuit therefore Programming Switch 2 must be in the ON position
when Terminal J31 is used.
J31 is a 1/4" spade terminal located in the lower right midsection of the control circuit board. The terminal
is designed to provide ground control for a Bosch relay, Vanner part number 05235 or equal. Install a 1
amp fuse in line near the inverter.
2.15 (15) REMOTE CONTROL JACK J9
All Models
Jack J9 is an 8 wire modular jack for use with optional Remote Control Switch, Remote Control Adapter
or Remote Operating Panel.
2.16 (16) BATTERY TEMPERATURE COMPENSATION CONTROL JACK J1
Jack J1 is a 4 wire modular jack for use with optional Battery Temperature Sensor. The Battery
Temperature Sensor reduces charging voltage when the batteries are in a high ambient temperature.
2.17 (17) AUTOMATIC POWER MANAGEMENT (APM) Panel JACK J8
(Jack J8 is present on all models but is functional on IQC Models only.)
IQC Models
Jack J8 is a 4 wire modular jack for use with optional Remote Automatic Power Management (APM)
Panel, Vanner part number D07934. The optional Remote APM Panel allows the APM current setting to
be adjusted to suit the circuit breaker at the shore power source. Before inverter serial number 02154-
049638 the APM values are 10 amps, 15 amps, 20 amps, or 30 amps. After inverter serial number
02154-049638 the APM values are zero amps, 10 amps, 15 amps, and 30 amps. See Automatic Power
Management theory of operation for performance details.
