AC Test Points
2. If a system display is present, perform all programming for all functions.
These functions may include AC input modes, AC output voltage, input current limits, battery
charging, generator starting, and others.
AC input modes are described beginning on page 13 and are summarized on page 20. The
inverter’s individual operations are described beginning on page 21.
3. Turn on the inverter using the system display (or external switch, if one has been installed). The
Radian’s default condition is Off. Do not turn on any AC circuit breakers at this time.
4. Using a DVM or voltmeter, verify 120 Vac (or appropriate voltage) between the “L1” and “N” OUT
terminals, and between the “L2” and “N” OUT terminals. (See Figure 3 for AC test points.) The
inverter is working correctly if the AC output reads within 10% of 120 Vac or the programmed
output voltage.
5. Proceed past the items below to Step 6 on the next page.
To start a multiple-inverter (stacked) system:
1. Close the main DC circuit breakers (or connect the fuses) from the battery bank to the inverter.
Repeat for every inverter present. Confirm that the system display is operational.
2. With the system display, perform any programming for stacking and all other functions.
These functions may also include AC input modes, AC output voltage, input current limits, battery
charging, generator starting, and others. When stacking in parallel, all slave inverters will observe
the programming settings for the master. They do not need to be programmed individually.
AC input modes are described beginning on page 13 and are summarized on page 20. The
inverter’s individual operations are described beginning on page 21. Stacking is described
beginning on page 35. The MATE3 Configuration Wizard may be used to assist programming.
3. Turn on the master inverter using the system display (or external switch, if one has been installed).
The Radian’s default condition is Off. Do not turn on any AC circuit breakers at this time.
Metal pads are located at these
locations. In commissioning,
AC voltages can be measured at
this series of test points.
