Step by Step Output (Grid) Connection Instructions:
a. All electrical installations must be made in accordance with the locally applicable
electrical standards and the
National Electrical Code®
(NE, ANSI/NFPA 70) (see
National Electrical Code®
, section 690.8).
b. Tools required - Slotted screwdriver (blade width: 3.5 mm).
c. Do not use “wire nuts”.
d. Connection from Inverter:
to life due to electric shock. Ensure that
the two-pole circuit breaker is switched off and cannot be reconnected.
1. Route the AC cable of the utility grid through the knockout(s) or holes at the
bottom of the enclosure to the Output terminal(s) of the Multigate XT located at
the bottom of the enclosure (or directly to the Multigate terminals for the model
XT1E).
2. Strip 3⁄8 in. (10 mm) insulation off each of the input AC cable wires.
3.
NOTICE
- If the grounding conductor and L1 or L2 are swapped, the Sunny
Multigate could be damaged during commissioning.
4.
Route the AC cable(s) of the inverters through the knockout(s) or holes at the
bottom of the Multigate XT enclosure to the Input terminals of the Multigate XT
located at the bottom of the enclosure (or directly to the Multigate terminals for
the model XT1E), one inverter string per conduit.
Each inverter string is to be
connected with it’s own 3 conductor cable consisting of L1, L2, and PE. It is
prohibited to merge different PE conductors.
5. Connect all conductors according to the terminal labels as shown on the door
label.
6. Connect the grounding conductor of the AC cable(s) to the terminal(s) of the
Multigate XT. Make sure that the conductor is inserted into the terminal(s) right
up to the stop.
7. Connect the L1 conductor(s) of the AC cable(s) to the L1 terminal(s) of the
Multigate XT. Make sure that each conductor is inserted into the terminal right
up to the stop.
8. Connect the L2 conductor(s) of the AC cable(s) to the L2 terminal(s) of the
Multigate XT. Make sure that each conductor is inserted into the terminal right
up to the stop.
9. Tighten all terminal screws of the connecting terminal(s) using a slotted
screwdriver to the specified torque values on the door label or in the instruction
manual, Section 6.2.
10. Ensure that all conductors are connected properly and securely in place.
