Product Introduction 

Liebert NXC 

1.5.7

 

Maintenance Bypass Mode 

If the maintenance and repair for UPS is needed, you can switch the load to the Maintenance Bypass through maintenance 
bypass MCB (Miniature Circuit Breaker), and the power to the load is uninterrupted. The maintenance bypass Miniature Circuit 
Breaker is located on the rear panel of the UPS device, and the capacity meets the requirements of total load capacities. 

Note 

If the UPS has a malfunctions and can not work normally, please get in touch with the nearest Emerson branch office or local service center. 
It is prohibited to repaire by yourself, as the personnel injury and damage to the equipment may occur.
