Page 7: Introduction
SECTION 1 INTRODUCTION The Behlman INV-1200 series of DC to AC power inverters incorporate the latest in switched mode power technology to provide regulated AC power from a user supplied DC source. These devices produce a sinewave output comparable to that which is available from typical utility power. Each model provides electronic protection along with a high short term overload capacity making them ideal for many loads requiring large “in-rush”... -

Page 9: Installation
SECTION 2 INSTALLATION GENERAL WARNING INSTALLATION AND OPERATION OF THIS DEVICE MAY EXPOSE HAZARDOUS VOLTAGES. REFER TO QUALIFIED PERSONNEL ONLY. The INV-1200 series inverters are designed to be installed in a standard 19" relay rack or EIA type enclosure. A set of accessory rack “ears” are provided for this purpose. These rack mount adapter brackets may be mounted at the front panel or in the middle of the chassis. - Page 10 CAUTION FAILURE TO OBSERVE DC POLARITY ON THE INPUT TO THIS DEVICE MAY CAUSE DAMAGE TO INTERNAL CIRCUITRY. THIS WILL VOID EQUIPMENT WARRANTY FIGURE 2-1, INV1200 WIRING WITHOUT BYPASS OPTIONS Units supplied with the AC input bypass option will be wired slightly differently. To conform to NEC 250 the neutral is “carried through”...

Wiring (continued) The recommended wire size for each model is listed below in table 2-1. These sizes are based on a maximum wire length of 10 to 15 feet. Longer wires should be increased in diameter. MODEL # DC INPUT WIRING AC INPUT \ OUTPUT WIRING INV-1200-48-XX # 8 AWG (45 A) -
Page 13: Optional Step-Up Transformer
OPTIONAL STEP-UP TRANSFORMER The INV series can provide a 220VAC or 240VAC output with the addition of an external transformer chassis. With this option a second rack mountable chassis is provided to convert the standard 120VAC output to the higher value. In addition, the bypass option can also be included with the external transformer. -

SECTION 3 OPERATION CONTROLS AND INDICATORS Table 3-1 below lists and describes the various controls, indicators, and connectors associated with this model. Figures 3-1 & 3-2 illustrate the location of items listed in table 3-1. ITEM DESIGNATION FUNCTION POWER Front panel mounted magnetic circuit breaker, also serves as DC on/off switch. - Page 15 FIGURE 3-1 INV1200 FRONT PANEL FIGURE 3-2 INV1200 REAR PANEL OPERATION Connect the load to the inverter. If multiple loads are used it is good practice to switch all loads off before switching on the inverter. This will prevent multiple in-rush currents from tripping protective circuits in the inverter.

Page 16: Operational Considerations
OPERATION (continued) The A1 bypass function can be verified by removing the AC line input. This will cause the AC IN LED to turn red and the AC IN alarm contacts to change state. During this time the INVERTER and DC IN LEDs should remain green. Confirm an AC output from the output terminals or outlets. -
Page 17: Powering Motors
POWERING MOTORS Driving an AC motor presents a special problem. Most motors require a starting current that can be several times higher than the running current. This current may last for a few cycles to several seconds depending on the construction and mechanical load on the motor. This current is sometimes referred to as the motor’s “locked rotor”... -
Page 18: Troubleshooting
SECTION 4 TROUBLESHOOTING THEORY OF OPERATION The INV-1200 series utilizes high frequency, switched mode, power conversion to convert the incoming DC to an AC output. The first stage is a DC to DC converter which “steps - up” the input voltage to a regulated +/- 200 VDC. -

TROUBLESHOOTING In the event problems are encountered during the installation and operation of the inverter refer to the chart below before assuming the inverter is at fault. If it is determined the fault is with the inverter, contact Behlman Electronics for service information. SYMPTOM POSSIBLE CAUSE ACTION... -
