Figure 19: Attaching lugs to the DC wires
NOTE
Functional electrical earthing of DC-side negative or positive poles is prohibited
because the inverter has no transformer. Grounding (earth ground) of module
frames and mounting equipment of the PV array modules is acceptable.
6.
Fasten the nut of the DC terminals with a torque of 5.7 N*m.
CAUTION!
Ensure that the Plus (+) wire is connected to the + terminal and that the Minus
(-) wire is connected to the Minus (-) terminal connector.
7. Close the Synergy Manager cover and secure it by tightening the six screws with a
torque of .
CAUTION!
When installing a system with more than three strings per a single Synergy Unit
(whether connected directly or via a combiner box), fuses are required. In
SolarEdge system, 25A fuses must be used.
Connecting Ground and AC to the Synergy Manager
This section describes how to connect AC and Ground (also referred to Protective Earth
- PE) to the Synergy Manager.
The following cable and wire configurations can be used to connect the Synergy
Manager:
AC cable with L1, L2, L3, PE wires
AC cable with L1, L2, L3, N, PE wires
Three Phase Inverter with Synergy Technology P/N: SExxK-xxxxIxxxx SExxK-xxxxIxxxx
