8.1Preventive Maintenance

Toshiba's 1500 and 1500 Plus Series of uninterruptible power systems have been designed to provide years of trouble-free operation requiring a minimum of preventive maintenance.

The best preventive measure that the UPS user can take is to keep the area around the unit, particularly the air inlet vents, clean and free of moisture and dust accumulations. If the atmosphere of the installation site is very dusty, use a vacuum cleaner to periodically remove dust accumulations from the system. Schedule authorized service centers to perform internal parts inspections annually.

CAUTION

WARNING

Before performing any maintenance, the technician should be familiar with and follow the important safety instructions located on pages vi and vii.

Proper maintenance of the battery system of this unit by a qualified service technician is essential to the safety and reliability of your UPS system. Refer to service manual.

8.2Parts Replacement

The following list shows intervals for periodic maintenance and replacement of certain UPS parts.

1)Batteries: VRLA batteries are maintenance free with respect to electrolyte only. The charging voltage, temperature, performance and connection resistance must be monitored periodically. Necessary corrective actions must be made in order to assure safe reliable power is supplied by the UPS. The aforementioned items affect the life of batteries, so replacement should be done once every 3 to 5 years at a minimum. All of the batteries must be replaced at the same time.

Quarterly maintenance

a)Visual checks

1)Leakage

2)Corrosion on positive terminal

b)Check battery temperature at the negative terminal.

c)Measure and record the system float charging voltage.

d)Measure and record the individual units float charging voltage.

Semi-Annual maintenance

a)Repeat the quarterly checks.

b)Perform a 10 second high rate (e.g. 100 amp) load test on the individual batteries.

c)Optionally test for the purpose of trending the battery over time.

d)Re-torque all inter-battery connecting hardware (if applicable).

e)Perform inter-battery connector resistance checks.

2)Aluminum electrolytic capacitors: Replace once every 5 years.

3)Fuses: Replace once every 7 years (see output fuse rating chart on the following page).

4)Cooling fan: Replace once every 3 years.
