5.3 Mounting Instructions

 The Z10 series inverter is designed for both interior and exterior installations.
 Please mount the inverter in the direction as illustrated above.
 It is recommended that the inverter is installed vertically, with a max.15 degrees

backwards tilt.

 In order to view the LCD display and undertake maintenance activities, please install

the inverter at eye level.

 Ensure that the wall selected for installation is strong enough for the mounting

screws and can bear the weight of the inverter.

 Ensure the device is properly fixed to the wall.
 It is not recommended that the inverter is exposed to strong sunshine. The excess

heat may lead to power reductions.

 The ambient temperature of the installation site should be between -20 °C and

+60 °C ( between -4 °F and 140 °F ).

 Ensure the installation location is well ventilated. Insufficient ventilation may reduce

the performance of the electronic components inside the inverter and shorten the
lifespan of the inverter.

5.5 Mounting Procedure

1) Mark 4 positions of the drill holes on the wall according to the paper installation position
guide packed in the carton box.

19

2) Where the wall are marked, drill 4 holes. Insert the four expansion tubes into the holes
using a rubber hammer. Next insert the 4 screws through the mounting holes in the
bracket and then tighten the screws into the expansion tubes.

3) Check the 4 holes at the rear of the inverter then lift the inverter carefully, aligning the 4
holes in the inverter to the 4 hooks on the bracket. Finally gently attach the inverter to the
hooks.

20

4) Please carefully check the accessories in the original carton to make sure every necessary
part is used and nothing is missing during installation.

21

NOTICE

Electrical connections must be carried out in
accordance with the applicable regulations, such as
conductor sections, fuses, and PE connections.

DANGER

DANGER to life due to potential fire or electricity shock. When

the inverter powered up, comply with all applicable national
regulations and legislation concerning accidents prevention.
This inverter will be directly connected to a HIGH VOLTAGE
power generation device; the installation must be performed by
qualified personnel only in compliance with national and local
standards, regulations and legislation.

For Z10I13KDT, Z10I17KDT and Z10I20KDT, there are two MPP Tracker, and the DC
characteristics of them are illustrated as the following table.

Connection procedure by MC4:

Connect the PV modules and inverter using MC4 connectors below. Connect the
positive and negative terminals from the PV modules to positive (+) terminals and
negative (-) terminals on Z10 series inverter

Connection Procedure:

1) Switch off the DC breaker and secure against being switched back on inadvertently.

2) Strip the cable 7 mm.

3) Insert striped cable into contact barrel and insure all conductor strands are captured
in the contact barrel.

24

4) Crimp contact barrel by using a hex crimping die. Put the contact barrel with striped
cable in the corresponding crimping notch and crimp the contact.

5) Insert contact cable assembly into back of the male and female connector. A “click”
should be heard or felt when the contact cable assembly is seated correctly.

6) Wrest the cap by using a torque of 2.6~2.9NM.

7) After wresting the cap tightly, align the 2 half connectors and mate them together by
hand until a “click” is heard or felt.

8) When the separation of connectors is necessary, use the specified wrench tool to
separate. Please make sure the wedge side of the fingers face the male connector
and push the tool down, then separate the connector by hand. See below figure.

25

NOTICE

DC Switch (Optional) may be integrated or external to
Inverter, and it can be used to connect or disconnect the
DC source from Inverter.

DANGER

DANGER to life due to potential fire or electricity shock.

NEVER connect or disconnect the connectors under load.

12mm

9) If the input connector is not enough, you can adopt an optional “Y” connector as
pictured below:

10) Please use sealing caps for tight sealing of unplugged PV connectors.

If using H4 connectors, the operating procedure is similar as that of a MC4 connector.

6.4 AC side connection

Connection Procedure

1) Strip the cable 12mm

26

2) Insert the stripped cable into the cord end terminal and insert the assembly into the
barrel.

The cable will be similar to the below picture.

3) Insert the finished 5 lines of cable into the AC cover assembly with the following
sequence：

Open the plastic cover, use a slot type screwdriver to press the shrapnel in the indicated
position and then put the line in the right hole. Please note the sequence of the line shall
be in the right order of: L1,L2,L3,N,PE

NOTICE

The Z10 series inverter is not an aligned measuring
instrument for current, voltage or power consumption.
A slight deviation of a few percent points is inherent to
the system; the results from the inverter cannot be
used for grid balance calculations. An aligned meter
will be required to make calculations for the utility
company.

2. After cut off the AC side connection, unplug the
inputs from the PV generator and check the
peripheral AC system.

3. After the cause is cleared, re-plug the PV panel
and AC connection, and check PV-Inverter
status.

Grid Fault
Fac Failure: Fac Out of

Range
AC Voltage Out of

Range

1. Wait for a moment, if the grid returns to normal,
PV-Inverter automatically restarts.

2. Make sure grid voltage and frequency meet the
specifications.

Utility Loss

1. Grid is not connected.

2. Check grid connection cables.

3. Check grid usability.

4. If grid is ok, and the problem persists, maybe the
fuse in the inverter is open, please call service.

Over Temperature in
Inverter

1. The internal temperature is higher than specified
normal value.

2. Find a way to reduce the ambient temperature.

3. Or move the inverter to a cooler environment.

PV Over Voltage

1. Check the open PV voltage, see if it is greater
than or too close to 1000VDC (for Z10I13KDT or
Z10I17KDT or Z10I20KDT).

2. If PV voltage is less than 1000VDC, and the
problem still occurs, please call local service.

Permanent
Fault

Consistent Fault:
Fac differs for M-S

Vac differs for M-S
Fac, Vac Differs for M-S
Ground I differs for M-S
DC inj. differs for M-S

Disconnect PV (+) or PV (-) from the input, restart
the inverter.

AC Relay Check Fail

1. Disconnect ALL PV (+) or PV (-).

2. Wait for a few seconds.

3. After the LCD switches off, reconnect and check
again.

4. If the problems remain please call local service.
