1.3 Maintenance, servicing and faults
★
The UPS operates with hazardous voltages. Repairs may be carried out
only by qualified maintenance personnel.
★
Caution - risk of electric shock. Even after the unit is disconnected from the
mains power supply (building wiring socket), components inside the UPS
are still connected to the battery which are potentially dangerous.
★
Before carrying out any kind of service and/or maintenance, disconnect the
batteries. Verify that no current is present and no hazardous voltage
exists in the capacitor or BUS capacitor terminals.
★
Batteries must be replaced only by qualified personnel.
★
Caution - risk of electric shock. The battery circuit is not isolated from the
input voltage. Hazardous voltages may occur between the battery
terminals and the ground. Verify that no voltage is present before servicing!
★
Batteries have a high short-circuit current and pose a risk of shock. Take
all precautionary measures specified below and any other measures
necessary when working with batteries:
★
－
remove all jewellery, wristwatches, rings and other metal objects
★
－
use only tools with insulated grips and handles.
★
When changing batteries, replace with the same quantity and the same
type of batteries.
★
Do not attempt to dispose of batteries by burning them. It could cause
explosion.
★
Do not open or destroy batteries. Effluent electrolyte can cause injury to
the skin and eyes. It may be toxic.
★
Please replace the fuse only by a fuse of the same type and of the same
amperage in order to avoid fire hazards.
★
Do not dismantle the UPS, except the qualified maintenance personnel.
1.3.1 UPS and Battery Care
For the best preventive maintenance, keep the area around the UPS clean
and dust-free. If the atmosphere is very dusty, clean the outside of the system
11
with a vacuum cleaner. For long battery life, keep the UPS at an ambient
temperature of 25°C (77°F)
1.3.2 Storing the UPS and Batteries
When the UPS is intended to store for a long period, recharge the battery
every 6 months by connecting the UPS to utility power. The batteries charge to
90% capacity in approximately 4 hours. However, it is recommended that the
batteries charge for 48 hours after long-term storage.
1.3.3 Time to Replace Batteries
When the discharging time is less than 50% of specified after full charged, the
battery may need to be replaced. Please check the battery connection or
contact your local dealer to order new battery.
WARNING:
l
Turn off the UPS and disconnect the utility power cord from the wall outlet.
l
Servicing should be performed by qualified service personnel
knowledgeable of batteries and required precautions. Keep unauthorized
personnel away from batteries
l
Batteries can present a risk of electrical shock or burn from high short
circuit current. The following precautions should be observed:
1. Remove watches, rings, or other metal objects.
2. Use tools with insulated handles.
3. Do not lay tools or metal parts on top of batteries.
4. Wear rubber gloves and boots.
5. Disconnect the charging source prior to connecting or disconnecting
battery terminal.
l
When replacing batteries, replace with the same type and number of
batteries or battery packs. Contact your service representative to order
new batteries.
l
Do not dispose of battery in a fire. Batteries may explode when exposed to
flame.
l
Proper disposal of batteries is required. Refer to your local codes for
disposal requirements.
l
Do not open or mutilate the battery. Released toxic electrolyte is harmful to
skin and eyes.
