Step by Step Input (Inverter) 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. Do not
disconnect under load.
1. PV plug connections must not be disconnected while under load. They can be
placed in a no load state.
2. Ensure that the two-pole circuit breaker is switched off and cannot be
reconnected.
3. Ensure that the PV modules are covered.
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. Strip 3⁄8 in. (10 mm) insulation off each of the input AC cab
le wires.
6.
NOTICE
- If the grounding conductor and L1 or L2 are swapped, the Sunny
Multigate could be damaged during commissioning.
7. Be sure to observe the terminal labels on the Multigate XT, shown on the door
label.
8. Connect all conductors according to the terminal labels as shown on the door
label.
9. Connect the grounding conductor(s) of the AC cable(s) to the GND terminal(s)
of the Multigate XT. Make sure that each conductor is inserted into the terminal
right up to the stop.
10. 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.
11. 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.
12. 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.
13. Ensure that all conductors are connected properly and securely in place.
