Connecting Ground And Ac To The Synergy Manager - SolarEdge SEK-I Series Installation Manual

5. Connect the DC wires to the DC+ and DC- terminal blocks, according to the labels
on the terminals:
a. Use a standard flat-blade screwdriver to connect the wires to the spring-clamp
terminals. The screwdriver blade should fit freely in the terminal opening. Too
large a blade can crack the plastic housing.
b. Insert the screwdriver and firmly tilt it to press the release mechanism and open
the clamp.
c. Insert the wire into the top opening (see Figure 22 ).
d. Remove the screwdriver – the wire is automatically clamped.
CAUTION!
Ensure that the Plus (+) wire is connected to the + terminal and that the Minus
(-) wire is connected to the Minus (-) terminal connector.
ATTENTION!
Veillez à ce que le câble Plus (+) soit connecté au terminal + et que le câble -
soit connecté au connecteur terminal.
NOTE
For systems with four PV strings per unit or more, fuses
may need to be installed in both the positive and negative
conductors as required by NEC Article 690.9. For more
information, refer to the "String Fusing Requirements
http://www.solaredge.com/files/pdfs/string_fusing_requirements.pdf.
5. Close the Synergy Manager cover and secure it by tightening the six screws with a
torque of 2.6 ft.*lb.
6. Ensure proper conduit sealing; inspect the entire conduit run and use standard
conduit sealants to avoid water penetration.
