2. Lead the AC cable through the cable gland and the housing.
3. Remove a length of 40mm of the cable jacket and strip the wire insulation to a length of
18 – 19mm.
4. Each of the terminals are labeled. Ensure that conductors are secured
(2 N.m. torque) in the correct terminals.
5. Ensure the rib of the PV terminal blocks and the grooves on the housing engage
correctly and a “click” is heard or felt.

Over-Current Protection Device (OCPD) for the AC side
To protect the inverter's AC connection line, we recommend installing a device for protection
against over-current and leakage, with the following characteristics noted in Table 4.2:
RHI-1P5K-HVES-5G
RHI-1P7.6K-HVES-5G
RHI-1P10K-HVES-5G

Note:
AC Grid and AC Backup output 240V L1-L2.
For 120V load, auto-transformer is required in the system.
For detailed information about the autotransformer please refer to
Solis auto-transformer quick installation guide.
4.5 Battery Fuse Terminals
Battery power cables should be connected to the battery fuse terminals in the wiring
box through the BAT conduit.

Warning:
Observe the terminal layout of terminal block.
Do not connect the phase lines to “Ground” terminal, otherwise the inverter
will not function properly.
