USER S MANUAL 4 Edition Visicomm Industries LLC 4525 Sheridan Rd Racine WI 53403 1 INTRODUCTION The conversion of electrical power is an essential reguirement for export testing or operation of eguipment brought to the U S from abroad The KSS series Freguency Converter is designed to meet these needs as it supplies reliable pure and stable power at an affordable price This Converter is designed with the following unigue features e Double Conversion IGBT module Single control board design eliminates adjustment and minimizes maintenance LCD display for unit status user friendly design Special overload capacity design 150 overload for 30 sec Built in isolation transformer to ensure total isolation between the input and output e Special airflow control to avoid dust accumulation Suitable for rough operating environments Front door access for ease of installation and servicing Compact size light weight The complete package includes Main Converter x 1 User s manual x 1 Front door key x 1 Battery Bank x 1 Screw to secure battery plug to battery receptacle box 2 1 FRONT PANEL 11 LCD Display Selector Switch 12 Freguency Selector Switch 13 Main Input breaker SW1 Controls the A C commercial input power in addition this breaker trips if the output power is subjected to a dead short 14 Input terminal The input power lea
6. cover or attempt to service the unit on your own High Voltage may be present even when the unit is shut down e Please follow all operational instructions STORAGE The converter should only be stored if the battery is fully charged Avoid storage temperatures above 80 F as battery life is significantly shortened Every 90 days remove the unit from storage and plug in for 24 hours to recharge the batteries Batteries may be damaged if left in storage and not recharged every 90 days IMPORTANT NOTICE Please use same type and same power rating of batteries for replacement Do not attempt to replace with batteries that exceed the specified ratings 10 5 BATTERY FACTS The batteries are the only serviceable parts in the converter The expected life of the battery is approximately 3 5 years However frequent long discharges or ambient temperatures above 80 F will shorten battery life Therefore it is recommended to replace the batteries every 3 years after initiating the unit Rechargethe batteries every 3 months if not in use as the batteries have a self discharge characteristic 5 1 BATTERIES AND RECHARGING 1 Batteries will automatically recharge when the converter has AC input power applied and input breaker SW1 and battery br eaker SW2 are both on Typical time about 8 10 hours to 9096 capacity FIG 5 1 BATTERY BACKUP TIME CHART 2 Please contact Visicomm ifa battery bank with longer backup times are required
