6.0 Operating the UPS
6.1 Initial Battery Charge
The UPS batteries must be charged before it is used for the first time or when the unit
has not been used (ac source power removed) for more than 10 days. Use the following
procedure to recharge the batteries:
1) Close breaker (power on) at the UPS input distribution panel.
2) Move the UPS unit's MCCB switch on the rear panel ON (see Section 9.1 for
location). The UPS unit's battery charging circuit is now activated (Allow 24 hours
for the batteries to fully charge).
Notes:
1) The UPS can be used while the batteries are being charged. However, if a power
loss occurs before the batteries are fully charged, the back up time can be affected.
2) If the UPS is to be stored for long periods; the batteries should be recharged (see
Section 2.2 Storage of UPS Equipment).
6.2 Start-up Procedure
When turning on the UPS for the first time or if source power has been removed for
several minutes, the following full start-up procedure should be used:
1) Check that the MCCB switch, located on the rear panel (see Section 9.1), is in
the OFF position.
2) Check that the UPS STOP/RUN switch, located on the front panel (see Section 9.1),
is to the left (STOP position).
3) Switch on power to the UPS from the distribution panel (see Section 4.1).
4) Move the MCCB switch to ON. Output power is now provided to the load via the
unit's bypass circuit (See section 6.9.2 Circuit Bypass Mode). While in this mode
if a power failure occurs in the commercial power source, the UPS system will
lose power and power to the load device will be interrupted. The unit's battery
charging circuit and chopper circuit are now activated.
5) Move the unit's UPS STOP/RUN switch to RUN. Operation of the unit's inverter
begins and output power is now provided to the load through the inverter circuit
(see Section 6.9.1 AC Input Mode). The unit is now capable of providing conditioned
uninterruptible power to the load should the commercial ac power source fail.
6.3 Battery Check Function
Part of the UPS start-up procedure is an automatic Battery Check to see if its internal
batteries need to be replaced. During start-up, the UPS will discharge its batteries for
about five seconds. If the total battery voltage drops below acceptable limits during this
time, a Battery problem fault is displayed (see Section 7.1 Non-Fatal Fault Mode).
This display will continue for approximately 20 minutes.
Notes:
1) The Battery problem display may occur immediately after a full battery
discharge even if the batteries do not require replacement. However, if this
display occurs after at least 20 minutes of charging, the batteries should be
replaced.
