5.3 Connecting DC Input Power Cables
Connect the SUN2000 to PV strings using DC input power cables.
Prerequisites

PV modules generate electric energy when exposed to sunlight and can create an electrical
shock hazard. Therefore, when connecting DC input power cables, shield the PV modules
with opaque cloth.

Before connecting DC input cables, ensure that the voltage on the DC side is under the
safety limit (60 V DC) and that the DC SWITCH on the SUN2000 is OFF. Otherwise, high
voltage may result in fatal injury.
Ensure that the following requirements are met to prevent fire accidents:
