Figure 23: Connecting PV strings to a Synergy Manager with spring-clamp DC terminals
4.
Connect the 4-14 AWG ground wire of the conduit nut to the grounding terminal
block (bus-bar) in the Synergy Manager. Fasten the screw bus-bar to a torque of 2.2
lb.*ft.
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 23
).
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.
6. Close the Synergy Manager cover and secure it by tightening the six screws to a
torque of 2.6 ft.*lb.
7. Ensure proper conduit sealing; inspect the entire conduit run and use standard
conduit sealants to avoid water penetration.
