3.4.3.1 Connecting the inverter to the utility grid
All electrical installations must be carried out in accordance with the local standards and
the National Electrical Code® ANSI/NFPA 70 or the Canadian Electrical Code® CSA C22.1.
The AC and DC electric circuits are isolated from the enclosure. If required by section 250
of the National Electrical Code®, ANSI/NFPA 70, the installer is responsible for grounding
the system.
The grid voltage must be within the permissible range. The exact operating range of the
inverter is specified in section 10 “Specifications”.
3.4.3.2 Wiring procedure
CAUTION
RISK OF ELECTRIC SHOCK. Prior to starting the wiring procedure, ensure
that the three-pole circuit breaker is switched off and cannot be reconnected.
NOTE
Damage or destruction of the inverter's electronic components due to
moisture and dust intrusion will occur if the enclosure opening is enlarged.
CAUTION
Risk of fire if two conductors are connected to one terminal. If a
connection of two conductors to a terminal is made, a fire can occur.
NEVER CONNECT MORE THAN ONE CONDUCTOR PER TERMINAL.
NOTE
Use M10 crimp terminals to connect to the inverter AC terminals
.
Figure 3.18 Strip AC cable
NOTE
S2 (insulation stripping length) is 2mm-3mm longer than S1.
(OT cable terminal crimping area)
2) Strip the insulation of the wire past the cable crimping area of the OT terminal,
then use a hydraulic crimp tool to crimp the terminal. The crimped portion of the terminal
must be insulated with heat shrinkable tube or insulating tape.
1) Strip the end of AC cable insulating jacket about 11.8 inch then strip the end of each wire.
