3.0 Installation
3. AC breakers connections/operation:
Note: For the following steps, refer to Figure 3-36 for MPSL-30D and MPSH-30D models, Figure
3-37 for the MPSL-60S models, and Figure 3-38 for MPDH-30D models.
CAUTION: Ensure you have read your inverter’s owner’s manual and are familar with
the power-up test for your particualr inverter and remote control.
a. Now that the appropriate battery voltage is connected to the inverter, turn OFF all inverter
loads in the inverter load panel (i.e., sub-panel) and turn the inverter ON.
Info: If the inverter does not turn on, refer to the Troubleshooting section for your
particular inverter.
b. Connect an AC voltmeter (or multimeter set to AC Volts) to the Inverter AC Output
Terminals and verify the correct AC voltage from the inverter. Refer to Figure 3-36, 3-37, or
3-38 (depending on your MP model) to determine the correct inverter AC output voltage.
Info: If the inverter has a Search mode feature, the inverter’s AC full output voltage will
not be present/on until Search is turned OFF, or a large enough light bulb is connected
to bring the inverter out of Search mode.
If using a Magnum inverter, use a light bulb that requires more than 5 watts (5 watts
is the default setting) to bring the inverter out of Search mode; or, turn the Search
mode off (inverter full output will always be on) with a remote control (i.e., ME-RC,
ME-ARC, or ME-RTR).
CAUTION: To prevent damage to valuable equipment, DO NOT connect anything to the
output of the MP but a light bulb until all wiring and voltages are confi rmed to be correct.
c. Turn ON the AC OUT 1 breaker in the MP enclosure and confi rm that the inverter AC output
voltage is passing thru the AC OUT breaker by verifying that the inverter AC output voltage
is present on the AC Output Terminals.
d. Turn ON the INV BYP 1 breaker in the MP enclosure (BYPASS Operation) and verify that
the inverter AC output voltage is no longer present on the AC Output Terminals (all voltage
readings should be 0 volts AC).
e. Turn the inverter OFF.
f. Apply power from an external AC source (utility grid or AC generator) to the AC Input
Terminals and verify the correct AC voltage from the external AC source. Refer to Figure 3-36,
3-37, or 3-38 (depending on your MP model) to determine the correct AC input voltage.
g. Connect the voltmeter to the AC Output Terminals and check that the external AC source
voltage is passing thru the INV BYP breaker by verifying the AC source voltage is now present
on the AC Output Terminals.
h. Turn ON the AC OUT 1 and INV IN breakers in the MP enclosure (NORMAL Operation) and
wait for the inverter to connect to the external AC source (approximately 30 seconds). Verify
that the external AC source is present on the AC Output Terminals.
Info: Even though the inverter is turned off, with the external AC source connected
and the INV IN breaker turned ON, the external AC source will connect to the inverter
— after a brief period of time (normally within 30 seconds) — and pass-thru the AC
OUT breaker to the AC Output Terminals.
This concludes the MP functional test. If all steps pass, the MP enclosure is ready for use. Disconnect
all power to the MP enclosure and proceed to Section 3.14 to install the front cover.
If any of the steps fail, recheck your wiring connections within the Installation section and/or refer
to the Troubleshooting section for your inverter.
Note 1 - The INV BYP and AC OUT breakers are interlocked together. Physically turning ON one will turn
OFF the other, and vice versa.
