Output Waveform; Installation - CEN-TECH 60704 Owner's Manual & Safety Instructions

Output waveform

Sine
Wave
1. This Inverter's output is a Modified Sine Wave.
Power from most electric utilities is a Sine Wave.
Note: Only multimeters identified as "TRUE RMS"
will read Modified Sine Wave voltage accurately.

Installation

Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this document
including all text under subheadings therein before set up or use of this product.
This Inverter must only be connected to batteries with a output voltage of 12 volts DC.
Lower voltage will not operate the Inverter properly, and more voltage could damage the Inverter
or the device being powered. Do not use this Inverter with positive ground electrical systems.
The Inverter has a number of shut-down points,
for the safety of the operator, the Inverter, and the devices being used with it.
• If the DC input voltage drops too low,
the alarm on the Inverter will sound.
If the input voltage drops further, the Inverter will
shut down automatically to prevent permanent
battery damage. Recharge the battery soon.
• If the DC input voltage exceeds 15V
the Inverter will shut down automatically.
Note: Even though this Inverter has built-in mechanisms to minimize damage,
these situations should be avoided because they can still damage the Inverter or battery.
1. Place the Inverter on a dry, level, non-flammable,
stable surface. Make sure the Inverter has
adequate ventilation and is not in direct sunlight.
2. Connect one end of a ground wire (not included,
use at least recommended wire thickness from
specification sheet) to the wing nut located on the
back of the Inverter. Then connect the other end
of the ground wire to a paint/rust free grounded
metal surface, such as the vehicle chassis.

2. Modified Sine Wave (MSW) power is suitable
for most AC devices and power supplies used in
electronic equipment, transformers, and motors.
Do not use to power sensitive devices such
as medical equipment or computers.
Some audio equipment may perform poorly
if run on Modified Sine Wave power.
3. Sine Wave Inverters provide power that is identical
to, or even better than, the power supplied by
your power company. Motors start easier and run
cooler under Sine Wave power. Certain devices,
such as laser printers, variable speed motors and
digital clocks, require sine wave power to operate
properly. Sine wave Inverters are typically more
expensive for their capacity than other Inverters.
• If the output load power rises higher
than the rating power of the Inverter;
the Inverter may shut down automatically.
• The Inverter may automatically shut down
if its internal temperature gets too high.
3. Battery Type Selection:
• Use only deep cycle lead-acid batteries with this
Inverter, such as 12 volt marine/RV deep-cycle
batteries. Do not use automotive, engine starting
(SLI), or maintenance-free wet cell batteries with
this Inverter; they are designed for repeated,
shallow discharge and will wear out quickly.
• Gel and AGM (Absorbed Glass Mat)
batteries can be used with this Inverter,
but they require special charging procedures.
Refer to battery supplier's instructions.
