External Maintenance Bypass Switch with NH1
Separate bypass supply
The external manual bypass is connected to the mains supply in parallel with the UPS. If the UPS is switched off or removed for maintenance or service purposes or for replacement, the connected loads are supplied directly from the mains without interruption. Switching back to UPS operation is also possible without interruption. This work can be carried out without switching off the consumers during normal working hours. Result are cost savings and high availability security of the UPS system.
