WIRING

See Figure 2 for electrical connections.

1. Note that the unit has no ON-OFF switch – identify

some external means of removing the dc supply.

2. Connect the ac load to the terminals labeled AC OUT.

Either terminal can be connected to ac common.

3. Connect the negative dc supply lead to the terminal

labeled DC GND. Note: This terminal is not

connected to safety or case ground – it can not

provide a dc circuit ground.

4. Connect the positive dc supply lead to the terminal

labeled DC IN.

OPERATION

Dc voltage may be applied to the IQ DC Power Supply by

any number of methods. It will start reliably with a 250

Vdc step input from a contactor or with a slow ramp from

a dc power source.

When dc power is applied, the unit will wait approximately

21 seconds with both LED's on. After activating the ac

output the unit will blink the LED labeled D1 and may or

may not indicate an overload briefly when starting. The

various LED indications are listed below. Normal

conditions have D1 blinking and D2 dark; but D2 may

blink sporadically without indicating a problem.

AVERAGE-CURRENT OVERLOAD

D1 and D2

blinking alternately

PEAK CURRENT OVERLOAD OR OUTPUT SHORT

blinking

blinking ON or OFF sporadically, or ON

continuously.

To recover, remove or lighten load and wait two (2)

minutes for the start cycle to begin.
