Delta M125HV - Electrical Installation for DC Wiring

DANGER : ELECTRICAL HAZARD!!
- PV array converts sunlight into electric power with high DC voltage and high
DC current which can cause dangerous electrical shock hazard!
- Use an opaque material to cover the PV array before wiring or cabling.
- Ensure the correct polarities are connected when DC cabling is applied.
- The amount of PV module of each string within one MPPT should be the same
to avoid the circulating current between the strings.
- Before plug in the DC connectors, pay attention to the polar is correct.
Reverse positive and negative voltage, inverter will probably damage.
WARNING !
- The risk of electric shock and fire exists because of high DC and AC voltages.
- Only PV modules that are listed with system voltage under 1600V are permitted
for use.
- Ensure the two DC switches are placed in the "OFF" position, and the PV array
is disconnected when DC conductors are connected.
- Without rain cover or protection, never perform any wiring or maintenance operations
under rainy conditions.
- Please wipe the inverter case if it is wet to avoid water seepage.
- The PV Array current carrying conductors (positive or negative) must not be
referenced to ground.
ATTENTION
3.5 Electrical Installation for DC Wiring
DANGER : ELECTRICAL HAZARD!!
- In order not to damage the components in the inverter, don’t repeat to change
the status of DC Switch quickly, the correct operation is waiting for the LED
display show "green off and yellow flash" (No DC) or turn on the switch after
5 minutes later.
CAUTION: DC SWITCH ON/OFF !
DANGER!
- It is forbidden to open both doors at the same time.
