working with batteries:
1) Verify that the UPS is off and that the power cord is disconnected from the power source.
2) Remove watches, rings or other metal objects.
3) Use tools with insulated handles to prevent inadvertent shorts.
4) Wear rubber gloves and boots.
5) Do not lay tools or metal parts on top of batteries.
6) Determine if the battery is inadvertently grounded. If inadvertently grounded, remove
source of ground. Contact with any part of a grounded battery can result in
electrical shock. The likelihood of such shock will be reduced if such grounds are
removed during installation and maintenance.
7) Verify circuit polarities prior to making connections.
8) Disconnect charging source and load proir to connecting or diconnecting terminals.
9) VRLA batteries contain an explosive mixture of hydrogen gas. Do not smoke, cause a flame
or spark in the immediate area of the batteries. This includes static electricity from the body.
10) Do not attempt to open the batteries in order to add water or sample the specific gravity of the
electrolyte. The batteries are valve regulated lead acid type and such servicing is not
possible without damaging the battery.
11) Use proper lifting means when moving batteries and wear all appropriate safety clothing and
equipment.
12) Do not dispose of lead acid batteries except through channels in accordance with local, state
and federal regulations.
Proper maintenance to the battery system of this unit must be done by a
qualified service techincian, this is essential to the safety and reliability of

2.0 Inspection/Storage/Disposal
2.1 Inspection of the new Battery System
Upon receipt of the Battery System, a careful inspection for shipping damage should be
made.
After Uncrating:
1) Check the unit for loose, broken, bent or otherwise damaged parts. If damage
has occurred during shipment, keep all original crating and packing materials
for return to shipping agent. Warranty will not apply to units which are damaged
during shipment.
2) Check to see that the rated capacity and the model number specified on the
nameplate conform to the order specifications.
2.2 Storage of Battery equipment.
If the Battery System is to be subjected to long or short term storage the following
guidelines should be used.
Avoid:
1) Storage in sites subject to extreme changes in temperature or high humidity.
2) Storage in sites subject to exposure of high levels of dust or metal particles.
3) Storage on inclined floor surfaces or in sites subject to excessive vibration.
Before storing:
1) Charge the system's batteries.
2) Place the Battery System's input switch (MCCB-C) in the OFF position.
Storing:
1) Store within a temperature range of -20° to 40° C (-4° to 104° F).
2) For best results, store the UPS in the original shipping container and place on a
wood or metal pallet.
3) The optimum storage temperature is 21° C (70° F). Higher ambient
temperatures cause UPS batteries to need recharging more frequently.
4) Batteries need to be recharged to maintain life during storage. Please follow
recomended recharges for your condition.
A) If stored in an ambient temperature under 20° C (68° F); recharge the
batteries every 9 months.
B) If stored in an ambient temperature of 20° to 30° C (68° to 86° F); recharge
the batteries every 6 months.
C) If stored in an ambient temperature of 30° to 40° C (86° to 104° F);
recharge the batteries every 3 months.
2.3 Disposal
Please contact your state environmental agency for details on disposal of electrical
components and packaging in your particular area.
It is illegal to dump lead-acid batteries in landfills or dispose of improperly.
Please help our Earth by contacting the environmental protection agencies in your area,
the battery manufacturer, or call Toshiba toll-free at 1-800-231-1412 for more information
about recycling.

7.0 Preventive and Scheduled Maintenance/Parts Replacement
7.1 Preventive Maintenance
Toshiba's 1400XL Plus Series of UPS battery cabinets have been designed to
provide years of trouble-free operation requiring a minimum of preventive maintenance.
The best preventive measure that the battery cabinet 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.
TOSHIBA
CAUTION
WARNING
7.2 Parts Replacement
The following list shows intervals for periodic maintenance and replacement of certain
battery cabinet 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 once every 3 to 5 years as 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.
Before performing any maintenance the technician should
be familiar with and follow the important safety instructions
located on pages 1-1 and 1-2.
Proper maintenance of the battery system of this unit by a
qualified service techincian is essential to the safety and
reliability of your UPS system. Refer to service manual.
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.

A shunt trip for the DC breaker on the battery cabinet is provided. This device is operated
with an applied voltage of 120VAC. When voltage is applied, the shunt trip will cause the
breaker to switch to the OFF position disabling the battery cabinet.
