WARNING:
HIGH LEAKAGE CURRENT! EARTH CONNECTION IS NECESSARY
BEFORE CONNECTING PV PANEL.
Incorrect grounding can cause physical injury, death or equipment
malfunction and increase electromagnetic interference.
Make sure that grounding conductors are adequately sized as required by safety
regulations. Do not connect the ground terminals of the unit in series in case of a
multiple installation.
This product can cause current with a d.c. component. Where a residual current
operated protective device (RCD) or monitoring (RCM) device is used for
protection in case of direct or indirect contact, only an RCD or RCM of Type B is
allowed on the supply side of this product.
A RCD with a residual current setting of 30mA, located between the inverter and
the mains, shall be provided at the endue application!
2. 6 Connec t ing to PV Pan el (DC inpu t)
A. Under any condition! Make sure the maximum open circuit voltage (Voc) of
each PV string is less than 550VDC for JSI-6000TL and JSI-5000TL, less
than 500VDC for JSI-2000TL, JSI-2500TL, JSI-3000TL and JSI-3600TL, less
than 450VDC for JSI-1100TL and JSI-1500TL. The length of input wire must
be less than 30m. By the way, generally, in the lowest ambient temperature of
your installing field, the Voc of PV string is the highest.
B. Use MC4 (Multi-contact) connectors for PV array terminals.
C. Open DC Switch and Connect the positive and negative terminals from the
PV panel to DC switch, then to positive (+) terminals and negative (-)
terminals on the solar inverter. Each DC terminal on inverter can withstand
20Adc.
D. When connecting PV panels to DC Switch, then, DC Switch to the terminals
of inverter, please make sure the polarity is correct.
Incorrect polarity connection could permanently damage the unit.
Please confirm short-circuit current of the PV string. The total short-circuit
current of the PV string should be less than the inverter's maximum DC input
current.
E. High voltages exist when the PV panel is exposed to the sun. To reduce risk
