Battery Maintenance Guidelines The battery maintenance instructions listed below are for reference only. Battery manufacturer’s instructions for transportation, installation, storage or maintenance take precedence over these instructions. • • • • • • • • To prevent damage, inspect batteries every 3 months for: Signs of battery cracking, leaking or swelling. The battery should be replaced immediately by authorized personnel using a battery of the identical type and rating. Signs of battery cable damage.
Battery Safety Notes WARNING! Lead-acid batteries contain dangerous voltages, currents and corrosive material. Battery installation, maintenance, service and replacement must be performed only by authorized personnel. Chemical Hazards Any gelled or liquid emissions from a valve-regulated lead-acid (VRLA) battery contain dilute sulfuric acid, which is harmful to the skin and eyes. Emissions are electrolytic, and are electrically conductive and corrosive.
1.0 Introduction Grounding Connection Notes In order to provide a ready, reliable source of backup power it is necessary to connect the power supply to an effective grounding and Earthing system that not only provides for the safety of the service personnel responsible for its operation and maintenance, but also facilitates the proper operation and protection of the equipment within the network.
