Please contact the nearest authorized service center if any
maintenance or repair is needed.Contact your distributor for the
information of the nearest authorized service center. Do NOT repair
it by yourself, it may cause injury or property damage.
Before installing and maintaining the equipment, you should
turn the DC switch OFF to cut off the high voltage DC of the PV
array. You can also turn the switch in the PV combiner box OFF to
cut off the high voltage DC.When the battery needs to be installed,
please confirm the positive and negative terminals of the battery
and turn OFF the battery. Otherwise, serious injury may be caused.

Step 2 Lift the inverter from the packing case and move it to
the installation position.
To prevent device damage and personal injury, keep
balance when moving the inverter because the inverter is
heavy.
Do not put the inverter with its wiring terminals
contacting the floor because the power ports and signal
ports are not designed to support the weight of the
inverter. Place the inverter horizontally.
When placing the inverter on the floor, put foam or
paper under the inverter to protect its shell.
Attentio

3.7.Installing HYD 3000~6000-EP
Step 1 Determine the positions for drilling holes, ensure the
hole positions are level, then mark the hole positions using a
marker pen, use the hammer drill to drill holes on the
wall(ApertureΦ10 mm). When drilling, keep the impact drill
perpendicular to the wall and drill slightly deeper than the length
of the expansion pipe. After drilling, please check whether the hole
position is suitable with the back plate. If the error is too large,
please reposition the hole, as shown in Figure 3-5①.
Step 2 Slowly hammer the expansion screw into the drilled
hole,as shown in Figure 3-5②.
Step 3 Position the back plate well, place the shrapnel and
