3.3.3.3. DC Conductor Connection
To ensure the optimum performance of the inverter, please read
the following guidelines before performing any DC connections.
1. Confirm the maximum open circuit voltage of the PV modules
is lower than 1000V
DC
under any conditions.
2. Confirm that the PV modules for each MPPT within the
inverter are of the same type and specification before
connection.
NOTICE:
When installing 25A or 30A fuses, these fuses may not be installed in
adjacent fuse holders. An empty or unused fuse holder must be
situated between each 25A/30A fuse within each MPPT.
Use of different fuses or incorrectly sized fuses can cause damage to
equipment or create unsafe working conditions. Any damage
resulting from incompatible fuses is not covered by the CPS
warranty.
NOTICE:
Note 1: The temperature rating of the PV Source circuit conductors
should be no less than 90°C (194°F).
Note 2: The recommended fuse values are configured based on the
condition that the input strings are the same (module type and length).
Note 3: The temperature rating of the fuse holder terminals is (90°C)
for Mersen or Bussman components.
