3-3. Installation：
Where to install. The power inverter should be installed in a location that
Meets the following requirements：
3-3-1. Dry – Do not allow water to drip or splash on the inverter.
3-3-2. Cool – Ambient air temperature should be between 0℃and 33℃, the
cooler the better.
3-3-3. Safe – Do not install in a battery compartment or other areas where
flammable fumes may exist, such as fuel storage areas or engine
compartments.
3-3-4. Ventilated – Allow at least one inch of clearance around the inverter
for air flow. Ensure the ventilation openings on the rear and bottom
of the unit are not obstructed.
3-3-5. Dust – Do not install the Inverter in a dusty environments
where are dust, wood particles or other filings/shavings are present.
These dust can be pulled into the unit when the cooling fan is
operating.
3-3-6. 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 3-6).
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 also will
damage the Inverter.
WARNING!
Shock Hazard. Before proceeding further, carefully
check that the Inverter is NOT connected to any
batteries, and that all wiring is disconnected from any
electrical sources. Do not connect the output terminals
of the Inverter to an incoming AC source.

3-4. Quick hook – up and testing：
For a quick hook – up of the power inverter to check its performance
before going ahead with installation, please follow these guidelines：
3-4-1. Unpack and inspect the power inverter to check its performance
switch in the OFF position.
3-4-2. Connect the cables to the power input terminals on the rear panel of
power inverter. The red terminal is positive (+) and black terminal
is negative (-). Insert the cables into the terminals and tighten
screws to clamp the wires securely.
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.
WARNING!
Make sure all the DC connections are tight (torque
to 9 – 10 ft-lbs, 11.7 – 13 Nm). Loose connections
overheat and could result in a potential hazard.
10

3-4-3. Before proceeding further, carefully check that cable you have
connected does tie negative terminal of inverter to the negative
output power source.
CAUTION !
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.
3-4-4. Connect the cable from the negative terminal of the inverter to the
negative terminal of the power source. Make a secure connection.
3-4-5. Set the power switch to the “ON” position and the buzzer will send
out “Beep sounds” sounds at the moment the inverter will do
self-diagnosis and the LED’s indicators will also appear various
colors. Finally the buzzer will send out another “Beep” sound and
the Input Level LED indicators will turn to “Green” color and the
inverter starts working successfully.
3-4-6. Set the power switch to the OFF position, the inverter stops and all
the lights that are On, and then go Off.
3-4-7. 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 ad FLUKE 45 BECKMAN 4410 or TRIPLETT 4200 must be
used.
11

3-5. 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 ).
3-5-1. Neutral Grounding (GFCI’S)：
3-5-1-1. 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.
WARNING!
Risk of electronic shock. Use only Pass and Seymour, type
2091-W, 2094-W,GFCI receptacles.
Other types may fail to operate properly when connected to
this inverter equipment .
3-5-1-2. 230V models：There is no connection made inside the
Inverter from either the line or neutral conductor to the safety
ground.

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
waveform 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.
WARNING!
Do not operate the power inverter without connecting
it to ground.
Electrical shock hazard may result.
3-6. Making DC Wiring Connections：
Follow this procedure to connect the battery cables to the DC input terminals
on the Inverter. Your cables should be as short as possible ( ideally,
less than 10 feet / 3 meters ) and large enough to handle the required
current in accordance with the electrical codes or regulations applicable to
your installation.
Cables that are not an adequate gauge (too narrow) or are too long will
cause decreased inverter performance such as poor surge capability and
frequent low input voltage warnings and shutdowns.
These low input voltage warnings are due to DC voltage drop across the
cables from the inverter to the batteries.
The linger and narrower these cables, the greater the voltage drop.
WARNING!
The installation of a fuse must be on positive cable.
Failure to place a fuse on “+” cables running between
the inverter and battery may cause damage to the
inverter and will void warranty.
13

Increasing your DC cable size will help improve the situation.
Cotek recommends the following cables for optimum inverter performance
( apply both 120V and 230V versions )
Model No Wire AWG Inline Fuse
S600-112 # 4 100A
S600-212 # 4 100A
S600-124 # 6 50A
S600-224 # 6 50A
Also, use only high quality copper wiring and keep cable length short, a
maximum of 3-6 feet.

3-7. Inverter Operation：
To operate the power inverter, turn it on 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. Controls and indicators：
The ON / OFF switch turns the control circuit in the power inverter
on and off. It does not disconnect power from the power inverter.
The Inverter operates from an input voltage ranging from：
10.5 to 15.0 VDC for 12V models
21.0 to 30.0 VDC for 24V models
42.0 to 60.0 VDC for 48V models
The Inverter will indicate high and low DC voltage conditions as
follows：
Model Dc Input over
