5. INSTALLATION
5.1 Unpacking and Inspection
Befare installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should
have received the following items inside of package:
• The unit x 1
• User manual x 1
• Communication cable x 1
5.2 Preparation
Before connecting all wirings, please take off bottom
cover by removing two screws as shown below.
5.3 Mounting the unit
Consider the following points before selecting where to install:
• Do not mount the inverter on flammable construction
materiaIs.
• Mount on a solid surface
• Install this inverter at eye level in order to allow the LCD display
to be read at all times.
• The ambient temperature should be between 0ºC and 55ºC
to ensure optimal operation.
• The recommended installation position is to be adhered to the
wall vertically.
• Be sure to keep other objects and surfaces as shown in the
right diagram to guarantee sufficient heat dissipation and to
have enough space for removing wires.
SUITABLE FOR MOUNTING ON CONCRETE OR OTHER
NON-COMBUSTIBLE SURFACE ONLY.
Install the unit by screwing three screws.
It’s recommended to use M4 or M5.
5.4 Battery connection
Caution:
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. Please refer to typical
amperage in below table as required fuse or breaker size.
WARNING! AII wiring must be performed by a qualified
personnel.
WARNING! 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.

Please follow below steps to implement battery connection:
1. Assemble battery ring terminal based on recommended battery cable and tenminal size.
2. Connect all battery packs as units requires.
Note: Please only use sealed lead acid battery or sealed GEL/AGM lead-acid battery.
3. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the bolts are
tightened with torque of 2-3 Nm. Make sure polarity at both the battery and the inverter/charge is correctly
connected and ring terminals are tightly screwed to the battery terminals.
Warning: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
Caution!! Do not place anything between the flat part of the inverter terminal and the ring tenminal. Otherwise,
overheating may occur.
Caution!! Do not apply anti-oxidant substance on the tenminals before terminals are connected tightly.
Caution!! Before making the final DC connection or closing DC breaker/disconnector, be sure positive (+) must
be connected to positive (+) and negative (-) must be connected to negative (-).
5.5 AC Input/Output connection
Caution!! 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 PDA5500-STATION.
Caution!! There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input and
output connectors.
WARNING! AII wiring must be performed by a qualified personnel.
WARNING! 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.

PDA5500-STATION 8AWG 1.4~1.6 Nm
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.

Warning:
Be sure that AC power source
is disconnected before
attempting
to hardwire it to the unit.
4. Then, insert AC input wires according to polarities indicated on terminal block and tighten terminal screws.
Be sure to connect PE protective conductor ( ) first.
Ground (yellow-green}

N Neutral (blue}
5. Make sure the wires are securely connected.
Caution: Important!!
Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause utility
short-circuited when these inverters are worked in parallel operation.
Caution:
Appliances such as air conditioner are required at least 2~3 minutes to restart because it’s required to have
enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a short
time, it will cause damage to your connected appliances. To prevent this kind of damage, please check
manufacturer of air conditioner if it’s equipped with time-delay function before installation. Otherwise, this
inverter/charger will trig overload fault and cut off output to protect your appliance but sometimes it still causes
internal damage to the air conditioner.
