Product Usage Instructions
Mounting
- Install four cushion blocks on Three-phase EPS Box with
self-tapping screws. - Use Three-phase EPS Box with cushion blocks as a template to
mark the four holes’ position on the wall with a marker pen. - Drill holes with a 6 driller carefully. Make sure the holes are
deep enough for installing. Install the expansion tubes through
cushion blocks into the holes and tighten them. - Install the expansion screws with a screwdriver to fix the
Three-phase EPS Box.
Wiring Connection
Wires Making
Prepare wires as below. Use the diagonal plier to strip 15mm of
insulation from the side of the wire.
- L wire x9 pcs
- N wire x3 pcs
- GND for EU x1 pcs (or N wire for AU x1 pcs)
If AWG-10 wires are used, pass the wires through the silicone
sleeves to avoid leakage at the insertions.
Grid-Wires Connection
Use the manual wrench to screw off the cap on the cable nut,
then insert Grid-L wires and Grid-N wires into the ports
(L1,L2,L3,L4) of contactor A through the cable nut and tighten them
with a screwdriver.
EPS-Wires Connection
Screw off the cap on the cable nut, then insert EPS-L wires and
EPS-N wires into ports (L1,L2,L3,L4) of contactor B through the
cable nut and tighten them with a screwdriver.
Load-Wires Connection
Screw off the cap on the cable nut, then insert Load-L wires and
Load-N wires into ports (T1, T2, T3, T4) of contactor C through the
cable nut and tighten them with a screwdriver.
Earth-Wire Connection
In EU, insert GND wire into port of contactor (B: L4) through
the cable nut and tighten it with a screwdriver. In AU, insert N
wire into ports of contactor(A: L4&B: L4).
