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)
