The remote computer will see the Dashboard related to this unit
§
Check the “Status” portion of the Dashboard to see the status of the 8 types of protection / alarm
warnings (See Section 13.3)
• Using “E-Mail Notify” Section of the Dashboard, selected protection / alarm warning(s) can be e-mailed
to specified e-mail addressee.
11.10 INTERNAL DC SIDE FUSES
The following DC side fuses have been provided for internal protection of the DC input side:
• PSR-1200-24: 4 pieces of 20A fuses in parallel = 80A total. Each fuse: Mini Blade Fuse 32 VDC, 20A. Littel
Fuse: 0297020.WXN or equivalent.
• PSR-1200-48: 4 pieces of 10A fuses in parallel = 40A total. Each fuse: Mini Blade Fuse 58 VDC, 10A. Littel
Fuse: 0997010.WXN or equivalent.
11.11 REVERSE POLARITY AT THE DC INPUT TERMINALS
The Positive of the battery should be connected to the Positive DC input terminal of the inverter and the
Negative of the battery should be connected to the Negative DC input terminal of the inverter. A reversal of
polarity (the Positive of the battery wrongly connected to the Negative DC input terminal of the inverter and
the Negative of the battery wrongly connected to the Positive DC input terminal of the inverter) will blow
the external / internal DC side fuses. If the DC side fuse is blown, the Inverter will be dead. However, if AC
GRID input is available, it will bypassed through withe the following indications:
• LED marked "AC GRID" will be GREEN
• LED marked "INVERTER" will be OFF
• LED marked "BYPASS" will be GREEN
• LED marked "ALARM" will be OFF
i
INFO
Reverse polarity connection is likely to damage the DC input circuitry. The internal fuse(s) should be
replaced with the same size of fuse(s) used in the unit. If the unit does not work after replacing the
fuse(s), it has been permanently damaged and will require repair / replacement (Please read Section 11
- “Troubleshooting Guide” for more details).
!
CAUTION!
Damage caused by reverse polarity is not covered by warranty! When making battery connections
on the input side, make sure that the polarity of battery connections is correct (Connect the Positive
of the battery to the Positive terminal of the unit and the Negative of the battery to the Negative
terminal of the unit). If the input is connected in reverse polarity, DC fuse(s) inside the Inverter /
external fuse will blow and may also cause permanent damage to the Inverter.
