Start-up and shut down SPA system
Attention of the installation
8
Users can start-up SPA inverters through following steps
：
•Turn the switch on in turn of Grid and battery.
•When the LED turns green, the working information on LCD indicates the successful
start-up of SPA series.
•
•Waiting until LED and LCD display have gone out, the SPA is shut down completely.
Turn the switch off in turn of Grid and battery.
7.1 Start-up the SPA system
7.2 Disconnect the SPA system
Heat dissipation performance is very important when SPA series work under the
environment of high temperature.Better heat dissipation can reduce the possibility of
SPA series stops working. The SPA series is fanless and belongs to natural cooling. The
hot air on the top of the radiator is matched with the battery. The environment is IP65.
Please pay attention to the temperature of the installation environment, to ensure that
the battery's safety and the normal work of the machine.
When use battery, please pay attention to the follow information:
Caution: Do not dispose of batteries in a fire. The batteries may explode.
Caution: Do not open or damage batteries. Released electrolyte is harmful to the skin
and eyes.
It may be toxic.
Caution: A battery can present a risk of electrical shock and high short-circuit current.
The following precautions should be observed when working on batteries:
•Remove watches, rings or other metal objects.
•Use tools with insulated handles.
•Wear rubber gloves and boots.
•Do not lay tools or metal parts on top of batteries.
•Disconnect charging source prior to connecting or disconnecting battery terminals.
•Determine if battery is inadvertently grounded. If inadvertently grounded, remove
source from ground. Contact with any part of a grounded battery can result in electrical
shock. The likelihood of such shock can be reduced if such grounds are removed during
installation and maintenance (applicable to equipment and remote battery supplies not
having a grounded supply circuit).
If SPA series doesn't work for overheating or too cold, solve it according to the following
methods:
•Confirm whether the radiator air duct installation is reasonable, choose the appropriate
position before installation.
•If lead-acid batteries are connected, confirming the NTC of battery is in a good
installation.
•Confirm whether the battery temperature is too high, too high temperature of battery
can also lead to SPA fail to work, at this point, to ventilation, cooling or handle to the
battery.
•If temperature is low, also can appear the battery low temperature protection. The
battery will start with small load in low temperature output. After temperature back to
normal system can work normally. Please be patient at this time.
•If the temperature is too low, it is possible that battery will be low temperature
protection, at this time, please pay attention to the working temperature range listed in
the specifications of the book.
•Servicing of batteries should be performed or supervised by personnel knowledgeable
about batteries and the required precautions.
•When replacing batteries, replace with the same type and number of batteries or
battery packs.
•General instructions regarding removal and installation of batteries.
Remark: All of above action should be operated by professional person, if you want to do
these works, you must make sure the whole system are off.
