8-8 Start-Up Procedure (Parallel UPS—MUS)
• Connect the parallel configuration cable A (shipped with each
UPS) to the DB9 parallel configuration port B of each UPS
system. Note: Before starting up the Parallel UPS system, ensure
that the “Parallel ID” is different for each UPS and parallel group
is set to 2. See
Section 10-5-5
for more details.
Refer to
Section 6-8 or 6-9
for the appropriate settings of the
parallel port DIP switches and parallel cable connections.
• With each UPS system’s external battery cabinet connected, switch
on the external battery cabinet circuit breaker switch of each
battery cabinet.
• Confirm that the manual bypass breaker Q3 on each UPS system is
off. Switch on the bypass input circuit breaker switch Q2 of each
UPS system. After a brief initialization process, the LCD screen
will show “ON AUTO BYPASS” and the “BYPASS” LED will
illuminate.
• Switch on the main input circuit breaker switch Q1 of each UPS
system.
• Press the ON button A of one of the UPS systems for 3 seconds
(until you hear a beep), then release the button. The inverter will
activate and synchronize with the bypass source. Press the ON
button for each of the other UPS systems for 3 seconds (until you
hear a beep), then release the button. When the inverter of each
UPS system is operating normally, they will automatically switch
from auto bypass mode to on-line (normal) mode at the same time.
The “BYPASS” LEDs
B will turn off and the “NORMAL” LEDs
C will illuminate.
• Check the output voltage of each UPS system. The phase voltage
deviation between each UPS system should be less than 5V. If the
phase deviation is within the acceptable range, switch on the output
circuit breaker switch
Q4 of each UPS system. Note: For more
information on checking the output voltage of each UPS system,
see
Section 10-4 .
