Others
With the ingress of protection IP65, the inverter can be installed outdoors. According to
EMC requirements and noise level, the inverter should be installed in industrial
environment or outdoors.
After cable connection, gaps around the inverter bottom should be sealed by fireproofing
mud. Fasten the waterproof terminals of communication cables and the like, and unused
waterproof terminals should be blocked by appropriate plugs, so to meet waterproof and
dustproof requirements.
Avoid direct exposing to sunlight. Otherwise, excessively high temperature may
reduce power generation.
5.3
Cable Routing Requirement
Cables used in this system generally include power cables and communication cables.
The communication cable needs to be routed away from the power cable, and the cables
need to form a right angle at the intersection. The communication cable needs to be as
short as possible and keeps a distance from the power cable.
Power cables and communication cables should be routed in different cable trenches to
avoid long-distance parallel cable routing, thereby reducing electromagnetic interference
due to output voltage transient.
The distance between the power cable and communication cable should be greater than
200mm. When the cables meet with each other, the cross angle should be 90°, and the
distance can be appropriately reduced.
The following table shows the recommended minimum distances between the
communication cable and power cable.
