EMIU 400W - 4 Option Mini Inverter

2.

The terminal blocks for connecting the 0-10V dimming control wires are located on the left-hand side of the cabinet as illustrated in figure 13.

3. Connect the Lighting Control signal cables from the external Lighting Dimming Control panel to the terminal blocks identified by IN1, IN2, IN3 

or IN4 in the Mini Inverter. Wiring is polarity sensitive. Observe the polarity of the cables to ensure proper installation. Purple is positive and 
grey is negative.  

4. Connect the Lighting Control signal cables from the lighting fixtures to the corresponding terminal blocks identified by OUT1, OUT2, OUT3 or 

OUT4 in the Mini Inverter. Wiring is polarity sensitive. Observe the polarity of the cables (

refer to figure 12

). Purple is positive and grey is 

negative.  

Note: Only one Lighting Control Override circuit has been shown for clarity. The same principle applies to all four Lighting Control Override 
circuits. 

8. INVERTER-ON DRY CONTACT

The Mini-Inverter also comes with one set of INVERTER-ON Dry Form “C” contact. 
The INVERTER-ON Dry Contact is identified as “INVON1” and its position is illustrated in 

Figure 12 and 13. 

 

The INVERTER-ON Dry Form “C” contact changes position in emergency mode.

INVERTER-ON Dry Contact Specification:

Maximum voltage: 30 VDC
Maximum current: 2A

The Lighting Control Override board has one extra INVERTER-ON Dry Form “C” contact identified as “INVON2”. “INVON2” has the same 
specifications as “INVON1” and can be used if needed. 

9. UNITS WITH NO AUTO-TEST (OPTION)

This equipment is not self-testing in conformance with the Life Safety Code, ANSI/NFPA 101.
