Cobra Electronics PI2000 manual Introduction, Caution Rechargeable Appliances

Introduction Caution: Rechargeable Appliances

To make the most of this inverter, it must be installed and used properly. Please read the installation and operating instructions carefully before installing and using it. Special attention must be paid to the CAUTION and WARNING statements in the manual. CAUTION statements specify conditions which could cause damage to the unit or other equipment. WARNING state- ments identify conditions that could result in personal injury or loss of life.

Cobra 2000W Output Waveform

The output waveform is referred to as “square wave” or “modified sine wave.” It is a stepped waveform designed to have characteristics simi- lar to the sine wave shape of utility power. A waveform of this nature is suitable for most AC loads (including linear and switching power sup- pliers used in electronic equipment, transformers and motors).

Caution: Rechargeable Appliances

Certain rechargers for small nickel cadmium bat- teries can be damaged if connected to the Cobra 2000W inverter. Two particular types of equip- ment are prone to this problem:

1.Small battery-operated appliances such as flashlights, razors, and night lights that can be plugged directly into an AC receptacle to recharge.

2.Certain battery chargers for battery packs used in hand power tools. These charges have a WARNING label stating that dangerous volt- ages are present at the battery terminals.

This problem does not occur with the vast majority of battery operated equipment. Most use a separate charger or transformer that is plugged into the AC receptacle and produces a low voltage output. If the label on the AC adapter or charger states that it produces a low voltage AC or DC output (less that 30 volts) the inverter will have no problem powering it safely.
