GreenPower Tesseract 5K14, Руководство по установке

Страница: 31 / 63

5.3.1 Installing the DC Input Power Cable
•
Before connecting the DC input power cable, ensure that the DC voltage is within
the safe range (lower than 60 V DC) and that the DC switch on the Tesseract
5K14 is OFF. Failing to do so may result in electric shocks.
•
When the Tesseract 5K14 is operating, it is not allowed to work on a DC circuit,
such as connecting or disconnecting a PV string or a PV module in a PV string.
Failing to do so may cause electric shocks.
•
If no PV string connects to the DC input terminals, do not remove the watertight
cap from the DC input terminals. Otherwise, the Tesseract 5K14 will not comply
with its Ingress Protection Rating.
Ensure that the following conditions are met. Otherwise, the Tesseract 5K14 will be
damaged, or even become a fire hazard.
•
The open-circuit voltage of each PV string is always lower than or
equal to 600 V DC.
•
The positive and negative terminals of a PV string connect to
corresponding positive and negative DC input terminals of the
Tesseract 5K14.
•
If polarity of the DC input power cable is reversed and the DC switch
is ON, do not turn off the DC switch immediately or unplug positive
and negative connectors. Wait until the solar irradiance declines at
night and the PV string current reduces to below 0.5 A, and then turn
off the DC switch and remove the positive and negative connectors.
Correct the string polarity before reconnecting the string to the
Tesseract 5K14.
•
Since the output of the PV string connected to the Tesseract 5K14 cannot be
grounded, ensure that the PV module output is well insulated to ground.
•
During the installation of PV strings and Tesseract 5K14, the positive or negative
terminals of PV strings may be grounded if power cables are not properly
installed or routed. In this case, an AC or DC short circuit may occur and damage
the Tesseract 5K14. This damage is not covered under any warranty or service
agreement.
