UPS Battery Maintenance Training

UPS Battery Maintenance

This UPS Battery Maintenance Training course is designed for personnel responsible for battery systems in substations, power plants and in industrial, commercial and institutional power systems that require emergency DC power.

This UPS Battery Maintenance Trainingcourse provides an understanding of battery backup failures such as: excessive or micro cycling, improper charging, poor temperature control, installation errors, manufacturing deficiencies and operational errors.

Battery and battery room safety requirements and inspection methods are also detailed along with personal protective equipment (PPE). Manufacturer installation and maintenance requirements are major components of this training.

A fully-functioning Uninterruptible Power Supply (UPS) system depends greatly on the batteries that are called on to serve emergency power during unexpected outages? Dp you know all the steps necessary to properly test and maintain your batteries? This 2-Day UPS Battery Systems training course is perfect for anyone who works in a facility when a power outages occur - the plant electrician, maintenance technician or a supervising engineer. Backup emergency batteries are essential, but only reliable if you have staff trained to properly test and maintain batteries so they perform in emergency situations.
