Connecting Ground And Ac Wires To The Synergy Manager - SolarEdge SE K Series Installation Manual

NOTE
Before connecting aluminum wires to the lugs:
a. Remove oxide from the exposed wires with emery paper or a steel wire
brush
b. Clean dust with a cloth and Isopropyl alcohol (IPA)
c. Coat wires with a designated antioxidant aluminum wire grease
immediately after cleaning
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.
5. Insert the DC wires into the DC terminals and fasten the Allen screw with a torque of
5 N*m for 25 mm
CAUTION!
Ensure that each Plus (+) wire is connected to its corresponding (-) terminal.
6. Close the Synergy Manager cover and secure it by tightening the six screws with a
torque of 3.5 N*m.
CAUTION!
When installing a system with more than three PV arrays 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 Wires 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 wire configurations can be used to connect the Synergy Manager:
L1, L2, L3, PE wires
L1, L2, L3, N, PE wires
WARNING!
To avoid shock hazard conditions, the PE wire must be connected to the
inverter before connecting the AC wires.
