106.3 Battery Voltage Check
Using a digital volt-ohm meter, check for correct nominal battery voltage between POS wires. Voltage reading should
be ± 10% of system’s nominal 12Vdc operating voltage.
107. Final Installation Checklist
IMPORTANT: Before proceeding to the System Start-Up Procedure
(Section 108) complete the Final Installation Checklist below.
1) Insure the
Vesta-M
cabinet(s) is securely fastened to a wall or other structure.
2) Insure that the input circuit breaker in the building service panel serving as the AC disconnect to the MPS system is in
the OFF position.
3) Check for proper ground connections in the
Vesta-M
unit cabinet.
4) Check for any loose wiring connections in the
Vesta-M
unit cabinet.
5) Check that correct nominal battery voltage (12 Vdc) is present in the
Vesta-M
unit between the battery’s NEG and POS
terminals.
6) Verify AC Input Voltage Selector Plug is installed and in the proper position to accept the AC input line voltage, system
voltage configuration.
CAUTION: Failure to install the Voltage Selector Plug will prevent system operation. Installing the Voltage Selector
Plug in the position that does not match the AC input line voltage will damage the unit, void the warranty and may
cause an dangerous or unsafe condition.
108. System Start-Up Procedure
IMPORTANT: The Vesta-M Micro inverter system is a sophisticated electronic backup power supply. Care must be
taken to follow the steps below in their exact sequence. Failure to do so may result in possible equipment failure.
CAUTION: Familiarize yourself with the shut down procedure in Section 200.1 before proceeding with the VST-M
system Start Up.
1) Apply utility AC power to the system by turning the branch circuit breaker in the main power panel to the ON position
2) Observe the LED Status indicators and verify the following:
A)
AC ON
indicator (red LED) is illuminated (indicates AC utility power is available to unit).
B)
CHG ON
indicator (green LED) is illuminated (indicates battery is connected and charger is operational).
3) Verify Normally -On fixtures or switched fixtures (where applicable) are illuminated (local fixture switch must be on position).
109. System Test
Momentarily push
TEST
switch and verify the following:
A)
INV ON
status indicator (yellow) illuminates (indicates inverter is operational).
B) Normally-on, normally - off and switched fixtures are illuminated (where applicable)
