5.2 How to start the UPS system from a fully powered-down condition
Initial conditions:
This procedure assumes the following initial conditions (for each module in a parallel system):
• The UPS maintenance bypass switch is open.
• The external UPS system output isolator on the load distribution panel is open.
• The UPS input/bypass supply fuses or (breakers) are open (
OFF
) at the incoming mains distribution board.
• The UPS module power switches (IA2) (IA3) and IA4) are open (
OFF
).
• The battery fuses (breakers) fitted in the battery cabinets/racks are open (
OFF
).
Power-up the load:
1. Turn ON the UPS system input/bypass mains supply (for ALL modules).
a) Power is now applied to the UPS module(s), but it is turned OFF.
2. On the module control panel (of ALL modules) verify that:
a) The
LINE 1
LED is green.
b) The
BATTERY
LED is flashing red.
c) All other mimic LEDs are OFF
d) The LCD displays
LOAD OFF, SUPPLY FAILURE
.
If necessary press the
RESET
button to obtain this display.
3. Close the external UPS system output isolation device on the load
distribution panel.
4. Close the UPS maintenance bypass switch
(see the "IMPORTANT NOTE" above)
.
WARNING: The procedures given below must be performed by a trained operator.
WARNING: When the UPS system is operating on
BYPASS
or via the
MAINTENANCE BYPASS SWITCH
, the
load supply is unprotected if the bypass mains supply fails. It is essential that the load user is informed of this
possibility before you intentionally select these operating modes.
WARNING: When the UPS is shut down, power is still applied to the UPS input/bypass terminals unless the
mains supplies are isolated at the incoming switchgear panel. In a standalone cabinet installation it is not
permissible to turn off the external input/bypass mains supply if the load is intentionally connected via the
internal maintenance bypass switch (IA1) as this will also disconnect the load power.
IMPORTANT NOTE
In the following procedures all references to the ‘Maintenance Bypass Switch’ apply to the internal maintenance bypass
switch (IA1) a standalone UPS cabinet if it is not connected to an external maintenance bypass facility.
If an external maintenance bypass facility is installed (standard in a parallel-cabinet system) all references to the
‘Maintenance Bypass Switch’ apply to the maintenance bypass switch located in the external facility.
Key Point: In order to reduce the possible effects of high inrush currents that might occur when the load is
initially turned on, we recommend that you power-up the load when the UPS system is operating on the
maintenance bypass before transferring it to the UPS inverter(s), as described in this procedure.
CAUTION: You should familiarise yourself with the operation of the external maintenance bypass circuit
operation before using this procedure.
