6.5 UPS Startup
The Liebert
®
EXM
™
must be fully installed and commissioned before startup, and external power
isolators must be closed. Once those general conditions are met, the UPS may be started.
NOTICE
Risk of improper startup when feeding a downstream transformer. Can cause damage to connected
equipment.
If the UPS is supplying a downstream transformer not provided by Liebert
®
, the UPS should be put on
maintenance bypass to energize it to mitigate the risk of in-rush current.
6.5.1 Startup Procedure
To start the UPS from a fully powered-down condition:
1. Log in as Operator, Administrator or Service.
2. Ensure that the Liebert
®
power module assembly ready switches are latched (in Down position).
3. Close the external input circuit breaker and connect input power. The touchscreen activates.
4. The rectifier goes through its startup sequence and the bypass static switch is activated.
5. Close the external output circuit breaker.
6. Touch the OPERATE tab
7. Touch the Inverter On radio button. When asked to confirm, touch On again.
The power module run lights will start flashing green while the unit goes through the inverter startup
sequence. After about a minute, the inverter will turn On, the static bypass will open and the power module
run lights will be solid green.
8. Close the battery breaker.
6.5.2 Startup in Eco Mode
Eco Mode is available only on a single-module Liebert
®
EXM
™
.
1. Log in as Operator, Administrator or Service.
2. Touch the OPERATE tab.
3. Touch Energy Saving Mode Activation Setup.
4. In the drop-down menu, touch Enable.
5. Touch Save.
The UPS should now be in 0static bypass mode with the inverter on standby. The status bar at
the top of the screen will say ENERGY SAVING MODE ACTIVE.
WARNING
Risk of electrical shock and arc flash. Can cause property damage, injury and death.
During this procedure the output terminals will become live.
If any load equipment is connected to the UPS output terminals, please check with the load
user and ascertain whether it is safe to apply power to the load. If the load is not ready to
receive power, then ensure that it is safely isolated from the UPS output terminals.
AVERTISSEMENT
Risque d’arc ou de décharge électrique pouvant entraîner des dommages matériels, des
blessures et même la mort.
Durant cette procédure, les bornes de sortie seront sous tension.
Si un équipement chargé est raccordé aux bornes de sortie du système ASC, veuillez vous
informer auprès de l’utilisateur de la charge s’il est sécuritaire d’appliquer une alimentation
à la charge. Si la charge n’est pas prête à recevoir une alimentation, alors assurez-vous
qu’elle est isolée sécuritairement des bornes de sortie du système ASC.
