5 MAINTENANCE

5.1 Cleaning the UPS

Clean the UPS periodically, especially the ventilation holes, to ensure free air flow inside the UPS. If
necessary, clean the UPS with a vacuum cleaner or wipe with a dry cloth. Confirm that the ventilation
holes are unobstructed.

5.2 Routine Maintenance

There are no user serviceable parts in the UPS. Attempting to service the unit yourself can void the
warranty.
Any routine maintenance other than cleaning, must be performed by a Vertiv service technician. Visit

Battery Safety
If the battery kit is damaged in any way or shows signs of leakage, contact Vertiv technical support
immediately. Handle, transport, and recycle batteries in accordance with local regulations.
WARNING! Risk of electrical shock. Can cause personal injury and death. When connected
together, battery-terminal voltage is potentially lethal. Be constantly aware that the battery
system contains high DC and AC voltages. Check for the presence of voltage using DC and AC
voltmeters before making contact with terminals.
CAUTION: Do not dispose of the battery in a fire. The battery may explode. Do not open or
damage the battery. Released electrolyte is harmful to skin and eyes. If electrolyte comes into
contact with the skin, wash the affected area immediately with plenty of clean water and get
medical attention.
A battery can present a risk of electrical shock and high short-circuit current. The following precautions
should be observed when working on batteries:
• Remove watches, rings and other metal objects.
• Use tools with insulated handles.
• Wear rubber gloves and boots.
• Do not lay tools or metal parts on top of batteries.
• Disconnect charging source prior to connecting or disconnecting battery terminals.
• Determine if the battery is inadvertently grounded. If it is inadvertently grounded, remove the
source of the ground. Contact with any part of a grounded battery can result in electrical
shock. The likelihood of such shock will be reduced if grounds are removed during installation
and maintenance (applicable to a UPS and a remote battery supply not having a grounded
supply circuit).
