Turning off the unit will not reduce this risk.
8. NEVER charge a frozen battery.
9. For optimum operation of this inverter, please follow required spec to select appropriate cable size. It’s
very important to correctly operate this inverter.
10. Be very cautious when working with metal tools on or around batteries. A potential risk exists to drop a
tool to spark or short circuit batteries or other electrical parts and could cause an explosion.
11. Please strictly follow installation procedure when you want to disconnect AC or DC terminals. Please
refer to INSTALLATION section of this manual for the details.
12. GROUNDING INSTRUCTIONS -This inverter should be connected to a permanent grounded wiring
system. Be sure to comply with local requirements and regulation to install this inverter.
13. NEVER cause AC output and DC input short circuited. Do NOT connect to the mains when DC input
short circuits.

For safety operation and regulation compliance, it’s requested to install a separate DC
over-current protector or disconnect device between battery and
inverter. It may not be
requested to have a disconnect device in some applications,
however, it’s still requested to
have over-current protection installed.
All wiring must be performed by a qualified personnel.
It's very important for system safety and efficient
operation to use appropriate cable for battery
connection. To reduce risk of injury, please use the proper
recommended cable and terminal size as below.
!
WARNING

Please follow below steps to implement lead-acid battery connection:
1. Assemble battery ring terminal based on recommended battery cable and terminal size
(same as Lead acid,see section 3.3.2 for details).
2. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure
the bolts are tightened with torque of 2-3Nm.Make sure polarity at both the battery and the
inverter/charge is correctly connected and ring terminals are tightly screwed to the battery
terminals.
Figure 3-7
CAUTION:
!
WARNING
Shock Hazard
Installation must be performed with care due to high battery voltage in series.
Do NOT place anything between the flat part of the inverter terminal and the
ring terminal. Otherwise, overheating may occur.
Do NOT apply anti-
oxidant substance on the terminals before terminals are
connected tightly.
Before making the final DC connection or closing DC breaker, be sure positive
(+) must be connected to positive (+) and negative (-) must be connected to
negative (-).

3.3.2 AC Input & Output Connection
CAUTION:
Suggested cable requirement for AC wires:
Tab le 3 -2
Please follow below steps to implement AC input/output connection:
1. Before making AC input/output connection, be sure to open DC protector or disconnector first.
2. Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor
N 3mm.
3. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal
screws. Be sure to connect PE protective conductor ( ) first.

CPS5000ECH48 1*8AWG 1.4-1.6Nm
CPS3000ECH48 1*10AWG 1.4-1.6Nm
Before connecting to AC input power source, please install a separate
AC breaker
between inverter and AC input power source. This will ensure the inverter can be
securely disconnected during maintenance and fully protected from over current of
AC input. The recommended spec of AC breaker is 50A for 5KVA.
There are two terminal blocks with “IN” and “OUT” markings. Please do NOT
mis-connect input and output connectors.
!
WARNING
All wiring must be performed by qualified personnel.
It's very important for system safety and efficient operation to use appropriate cable
for AC input connection. To reduce risk of injury, please use the proper recommended
cable size as below.
