3-1-2. ON / OFF switch：
Power ON/OFF switch, leave in the OFF position during installation.
3-1-3. Battery Voltage indicator：
The battery voltage bar graph indicates the voltage at the input
terminals of the power inverter. At low input current, this voltage is
very close to the battery voltage. At high input current, this voltage
will be lower than the battery voltage because of the voltage drop
across the cable and connections. Ideally, the voltage should remain
in the green Ares of the bar graph. If the voltage goes into the red
area at top and bottom of the graph, inverter may shutdown.
5
3-1-4. Battery Voltage indicator：
The AC load watt bar graph indicates the power drawn from the power
inverter by the load. For long term operation, the watt indicator
should remind in the green & orange area of the bar graph.
Short term operation is possible with watt indicator in the red area.
If the watt indicator rises to high values the bar will flash and the
inverter will shutdown to protect itself.
3-1-5. OVP：Over Voltage indicator：
The over voltage indicator indicates that the power inverter has shut
itself down because its input voltage exceeded 12 / 24 / 48VDC
version.
文管中心
3-1-6. UVP：Under Voltage Protection indicator：
發行章
The under voltage indicator indicates that the power inverter has shut
itself down because its input voltage fell below 12 / 24 / 48VDC.
3-1-7. OTP：Over Temperature Protection indicator：
The over temp indicator indicates that the power inverter has shut itself
down because its temp has become overheated. The power inverter
may overheat because it has been operated at power levels above its
rating, or because it has been installed in a location which does not
allow it to dissipate heat properly. The power inverter will restart
automatically, once it has cooled off.
3-1-8. OLP：Over Load Protection indicator：
The overload indicator indicates that the power inverter has shut itself
down because its output has been short circuited or drastically
overloaded.
Switch the ON/OFF switch to OFF, correct the fault condition, and then
switch the ON/OFF switch back to ON to reset the unit.
3-1-9. Power Saving：Power energy saving enable.

3-4. Installation：
Where to install. The power inverter should be installed in a location that
meets the following requirements：
3-4-1. Dry － Do not allow water to drip or splash on the inverter.
3-4-2. Cool － Ambient air temperature should be between 0°C
3-4-3. Safe － Do not install in a battery compartment or other areas where
flammable fumes may exist, such as fuel storage areas or engine
compartments.
文管中心
3-4-4. Ventilated － Allow at least three inch of clearance around the inverter
for air flow. Ensure the ventilation openings on the rear and front of
the unit are not obstructed.
發行章
3-4-5. Dust-free － Do not install the Inverter in a dusty environments where
are dust, wood particles or other filings/shavings.
These dust can be pulled into the unit when the cooling fan is
operating.
3-4-6. Close to batteries － Avoid excessive cable lengths but do not install
the Inverter in the same compartment as batteries.
Use the recommended wire lengths and sizes (see section 2-10).
Also do not mount the Inverter where it will be exposed to the gases
produced by the battery.
These gases are very corrosive and prolonged exposure will damage
the Inverter.
WARNING!
You may observe a spark when you make this
connection since current may flow to charge
capacitors in the power inverter.
Do not make this connection in the presence of
Flammable fumes. Explosion or fire may result.
10
3-5. Making DC Wiring Connections：
Follow this procedure to connect the battery cables to the DC input terminals
of the Inverter. Your cables should be as short as possible ( ideally, less
than 6 feet / 1.8 meters ) enough to handle the required current in accordance
with the electrical codes or regulations application. Cables are not an
adequate gauge ( too narrow ) or too long will decrease the inverter
performances such as poor surge capability and low input voltage warnings
frequently and shutdowns. UVP warning presents due to DC voltage drop
across the cables from the inverter to the batteries.
The longer or narrower the cables, the greater the voltage drop.
Increasing your DC cable size will help improve the situation.

3-6. AC Safety Grounding：
During the AC wiring installation, AC input and output ground wires are
connected to the inverter. The AC input ground wire must connect to the
incoming ground from your AC utility source.
The AC output ground wire should go to the grounding point for your loads
( for example, a distribution panel ground bus ).
Ground Fault Circuit Interrupters (GFCI)：
Installations in Recreational Vehicles ( for North American approvals ) will
require GFCI protection of all branch circuit connected to the AC output of the
hardwire terminal equipped Inverter. In addition, electrical codes require
GFCI protection of certain receptacles in residential installations.
While the pure sine wave output of the Inverter is equivalent to the wave form
provided by utilities, compliance with UL standards requires us to test and
recommend specific GFCI.
Cotek has tested the following GFCI － protected 20A receptacles and found
that they functioned properly when connected to the output of the Inverter.
文管中心
發行章
3-6-1. Neutral Grounding (GFCI’S)：
3-6-1-1. 120V models：The neutral conductor of the AC output circuit
of the Inverter is automatically connected to the safety ground
during inverter operation. This conforms to national
electrical code requirements that separately derived AC
sources (such as inverter and generators) have their neutral
conductors tied to ground in the same way that the neutral
conductor from the utility is tied to ground at the AC breaker
panel. For models configured with a transfer relay, while AC
utility power is presenting and the Inverter is in bypass mode,
this connection (neutral of the Inverter’s AC output to input
safety ground) is not present so that the utility neutral is only
connected to ground at your breaker panel, as required.
3-6-1-2. 230V models：There is no connection made inside the
Inverter from either the line or neutral conductor to the safety
ground.
13
3-7. Inverter Operation：
To operate the power inverter, turn it on by using the ON/OFF switch on the
front panel. The power inverter is now ready to deliver AC power to your
loads. If you are operating several loads from the power inverter, turn them
on separately after the inverter has been turned on.
This will ensure that the power inverter does not have to deliver the starting
currents for all the loads at once.
3-7-1. Unpack and inspect the power inverter, check to see that the power
switch in the OFF position.
文管中心
3-7-2. Connect the cables to the power input terminals on the year panel of
power inverter.
The terminal is positive (+) and black terminal is negative (-).
Insert the cables into the terminals and tighten allen nut to clamp the
wires securely.
發行章
WARNING!
Make sure all the DC connections are tight (torque to
9-10 ft-lbs, 11.7-13Nm). Loose connections will
overheat and could result in a potential hazard.
3-7-3. Before proceeding further, carefully check that cable you have just
connected does tie negative terminal of inverter to the negative output
power source.
WARNING!
Reverse polarity connection will blow a fuse in inverter
and may permanently damage the inverter.
Damage caused by reverse polarity connection is not
covered by warranty.
3-7-4. Connect the cable from the negative terminal of the inverter to the
negative terminal of the power source. Make a secure connection.
14
WARNING!
You may observe a spark when you make this
connection since current may flow to charge
capacitors in the power inverter.
Do not make this connection in the presence of
flammable fumes Explosion or fire may result.
3-7-5. Set the power switch to the ON position. Check the meters and
indicators on the front panel of the inverter. The voltage bar graph
should indicate 11 to 14 volts (22 to 28V when 24V version is used)
depending on the voltage of the power source. If does not, check
your power source and the connections to inverter.
The other indicators should be off.
文管中心
發行章
3-7-6. Set power inverter switch to the OFF position, the indicator lights may
blink and the internal alarm may sound momentarily.
The is normal. Plug the test load into the AC receptacle on the front
panel of the inverter. Leave the test load switch off.
3-7-7. Set power inverter switch to the ON position and turn the test load On.
The inverter should supply power to the load.
If you plan to accurately measure the true output r.m.s. voltage of
inverter, a meter such as FLUKE 45 BECKMAN 4410 or TRIPLETT
200 must be used.
15
3-8. Power output：
The inverter will operate most AC loads within its power rating.
When deeming whether a microwave oven can be operated by the inverter,
remember that the power commonly advertised for microwave ovens are the
cooking power (the power delivered to the food) not the power actually
consumed by the microwave oven. The microwave oven will consume 40%
to 100% more than its advertised cooking power. Check the rating sticker
on the back of the oven to determine its actual power requirements.
The 1500W inverter will operate small microwave oven (0.2 to 0.3 cubic foot
capacity) that draws about 1700 watts. It will provide 3 minutes of cooking
time. Some induction motors used in refrigerators, freezers, pumps, and
other motor operated equipment require very high surge currents to start.
The Power Inverter may not be able to start some of these motor even though
their rated current requirement is within the power inverter.
If motor is refused to start, observe the battery voltage indicator while trying to
start the motor. If the battery voltage indicator drops below 11 volts while
inverter is attempting to start the motor, this may be why the motor won’t start.
Make sure that the battery connections are good and the battery is fully
charged.

8-1-3. The RS232 interface of this unit employs ASCll code to implement the
asynchronous serial transmission control.
The byte structure is START BIP – 8 BIT DATA-STOP BIT Baud
rate：1200,2400,4800,(SET BY DIP-SW).
Parity check ：NONE, not settable
Data bit：8, not settable.
Stop bit：1, not settable.
20
8-2. Interface Command：
The buffer size used for the RS232 port is 12-bytes. This unit will ignore all
bytes more than this value.
During transmission, this unit (inverter) will indicate it is ready to receive data
from computer by the DTR line. A computer has to check the DTR line
before sending any information to this unit.
This unit is normally always ready to receive data while operating.
When a LF character (ASCll code 0AH) is received, this unit would finish the
receiving by clearing the DTR status and begin to interpret the received
information. The unit would execute the received command (AND/OR data)
if it is correct.
Irrespective of whether the command is accepted or not, the unit will always
send back a response signal to the computer and set DTR to ready for
receiving more incoming information.
文管中心

8-2-1. The Baud Rate of the RS232 interface is determined by S5 and S6 of
DIP-SW, as shows in Appendix A.
Note：You have to reset the unit after adjustment to activate the New
settings.
8-2-2. Illustration of the RS232 operation：
8-2-2-1. RS232 command
Command format：
This unit uses high-level language commands with a CR (0DH)
and a LF (0AH) as the end of the command.
The system would interpret and execute the command only
after these two characters are received.
After the unit execute the command, it would send a response
string to the computer.
The response string is as follows：
= > CR LF：Command executed successfully
? > CR LF：Command error, not accepted
! > CR LF：Command correct but execution error (e.g.
parameters out of range)
If the command needs any information from the unit, the unit
would send the information back to the computer (with CR
and LF) and then send the response string to the computer.

9-2. Power saving mode
MICROPROCESSOR BASED SINE WAVE INVERTER S-1500 SERIES
ENABLING AND DISABLING POWER SAVING MODE
9-2-1. When an inverter is powered on and is running in idle condition ( there
is no load or the load connected to the inverter has been switched off ),
it will still draw some power from the batteries for keeping the system
alive.
9-2-2. This inverter features a power saving “sleep” mode for conserving the
battery power during idle conditions. When this mode is enabled,
the inverter senses the output power being drawn and if this is less
than 2 to 15 watts, the inverter shuts down the output power. Only
essential systems are kept alive to reduce power consumption from
the batteries to a very low value of only about 1.5 watts. As soon as
a load is switched on, the inverter wakes up from its “sleep” condition
and restores the output power after a response time of about 8
seconds. Please note that on waking up from the power saving
“sleep” mode, the inverter requires some time to prepare all the
systems before it can start delivering power to the load. Hence, the
output power will not be available immediately but after a time lag of
approx. 15 to 18 sec. If using a hand tool or other appliance with a
trigger, keep the trigger pressed for some time till the power is
available to drive the tool / appliance.

9-2-3. The power saving “sleep” mode can be enabled or disabled with the
help of the power on / off switch or with the help of the optional remote
control. Procedure to switch between the two states is given at para
6 below. The inverter has been factory pre-set in the enabled
condition.
9-2-4. Power saving “sleep” mode, enabled
9-2-4-1. The front plate has a green led marked “power saving” for
indication of enabled state of power saving “sleep” mode
(here-in-after referred to as the green led)
28
9-2-4-2. The power saving “sleep” mode is enabled in either of the
following indications ( When inverter is in on condition )：
The green led flashing sequence is：
Flash-flash-gap-flash-flash-gap…….( power saving “sleep”
mode, idle condition or no load )
The green led is continuously lighted ( power saving “sleep”
mode, loaded )
9-2-5. Following indications will be observed when the inverter is powered on
and subsequently loaded and unloaded when power saving “sleep”
mode is in enabled condition：( the initial condition is that the inverter
is switch ed off and all loads are disconnected )
文管中心
9-2-5-1. Switch on the inverter. There will be 2 beeps and the green
led will start flashing with a flashing sequence of flash-flashflash……After about 3 seconds, there will be 1 beep, the
green led will stop flashing and it will be lighted continuously.
Output power will be available after about 15 to 18 sec from
the time the green led stops flashing. After the output power
is made available, the inverter searches if any load is
connected. If the load is less than 2 to 15 watts, the output
power is shut down after about 15 seconds from the time the
output power is made available.
The green led will start a flashing sequence of flash-flashgap-flash-Flash-gap…..( this indicates that the inverter is in
power saving “sleep” mode and is idling at no load )
發行章
9-2-5-2. If now a load more than 2 to 15 watts is switch ed on, the
green led stops flashing after about 3 seconds and will be
lighted continuously. After about 15 to 18 seconds after the
green led has stopped flashing and become steady, output
power will be available to the load. The green led will be
lighted continuously ( this indicates that the inverter is in
power saving “sleep” mode and is in loaded condition )
9-2-5-3. If the load is switched off, the output power will be shut down
after about 15 to 18 seconds and the green led will start
flashing with a flashing sequence of flash-flash-gap-flashflash-gap……( this indicates that the inverter is in power
saving “sleep” mode and is idling at no load )
29
9-2-6. Power saving “sleep” mode, disabled
9-2-6-1. The front plate has a green led marked “power saving” for
indication of enable state of power save “sleep” mode ( herein-after referred to as the green led )
9-2-6-2. The power saving “sleep” mode is disabled when the green
led marked “power saving” is off. In this mode the output
power is always available.
9-2-6-3. Following indications will be observed when the inverter is
powered on and subsequently loaded and unloaded when
power saving “sleep” mode is in disabled condition：( the
initial condition is that the inverter is switched off and all loads
are disconnected )

9-2-6-3-1. Switch on the inverter. There will be 2 beeps and
green led will start flashing with a flashing
sequence of flash-flash-flash…..After about 3
seconds, there will be 1 beep and the green led
will stop flashing and switch off. Output power
will be available after about 15 to 18 sec from the
time the green led switches off. The output
power will be always available, even in no load
idling condition.
The green led will be off all the time.
9-2-7. Switching between enabled and disabled states of power saving
“sleep” mode
9-2-7-1. Switching between enabled and disabled states of power
saving “sleep” mode can be done with the help of the power
on / off switch on the front plate of the inverter or with the help
of the optional remote control.
Switch on the front plate of the inverter is done as follows：
30
Switch on the front plate of the inverter is done as follows：
This procedure acts as a toggle i.e. If the inverter was in
enabled state before the procedure, it will switch to disabled
state after the procedure.
Likewise, if it was in disabled state before the procedure, it will
switch to enabled state after the procedure.
Switch off all the loads, switch off the inverter, disconnect all
loads. Switch on the inverter. There will be 2 beeps and
green led will start flashing with a flashing sequence of flashflash-flash…..( it will flash for approx. 3 seconds ).
Immediately after it starts flashing, switch off the power on /
off switch and immediately switch on again. This will
complete the switching procedure. The inverter will continue
its power on sequence and switch over to the new state.
文管中心
The power on / off switch should be switched off and on again
during the time the green led is flashing ( the green led will
flash with a sequence of flash-flash-flash…..For about 3
seconds after the inverter is powered on )
