First place the fixing hook at the bottom of keypad onto mounting claw on
keypad mounting hole, let forefinger press fixing flexible plate on top of keypad
and then push it inside, release it in proper location(after a crisp sound).
3.2.2 Plastic cover disassembly
Put the finger into handle hole on the bottom of cover, lift it, then you can
disassemble the cover.

(1)Before wiring, assure power supply is cut off completely for 10 minutes and all LED indicator ligh
extinguished.
(2)Before internal wiring, confirm that DC volt. Between main loop end P+ and P- fall down to below DC36V.
(3)Wiring can only be done by professional person trained and qualified.
(4)Before electrification, check if voltage grade of the inverter is in line with that of power supply volt.,
otherwise will cause personnel injured and device damaged.
!
(1)Assure power cuf off completely for above 10 minutes before wiring, otherwise have danger of
getting electric shock.
(2)Forbid connecting power wire to output U, V, W of the inverter.
(3)There is current leakage in the inverter and leak current of middle/high power inverter is bigger than 5mA,
for safety reason
，
inverter and motor must be earthed safely, commonly use 3.5mm² above copper wire as
ground wire and ground resistance smaller than 10
Ω
.
(4)Before shipment compression resistance test of the inverter is passed
，
so user should not conduct
compression resistance test again.
(5)Should not assemble electromagnetic contactor and absorbing capacitance or other absorbing device,
see Fig.3-3.
(6)To be convenient to over current protect of input side and power off maintenance inverter should be
connected to power supply through relay.
(7)Connecting wire for relay input and output loop(X1~X8, OC1~OC4, FWD, REV), should use above
0.75mm² glued wire or shielding wire
，
one shielding layer end hung in the air, the other connected to
grounding end PE or E, connecting wire shorter than 20m.
