Maintenance Mode
Principle – General Use
The Maintenance
Mode can be used to reduce arc flash levels.
Refer to Std. NFPA70E.
DO NOT attempt to install or perform maintenance on equipment while it is
energized. Severe personal injury or death can result from contact with
energized equipment. Verify that no voltage is present before opening
doors of the switchboard.
If maintenance will be performed on a device, special protective clothing
and equipment MUST BE USED and all industry standard procedures MUST
BE FOLLOWED. Failure to do so can result in severe personal injury or
death.
The Maintenance Mode can improve safety by providing a simple and reliable method to reduce fault clearing time and
lower incident energy levels at energized panels.
The Maintenance Mode allows the User to switch to more sensitive
settings via the HMI/panel, Communication, or via a Digital Input while maintenance work is being performed at an
energized panel or device.
The more sensitive settings provide greater security for maintenance personnel and helps
reduce the possibility of injury.
The status of the Maintenance Mode (active/inactive) is stored power fail-safe.
Manual activation is only possible via the HMI/panel (not via PowerPort-E).
The Maintenance Mode can be activated:
Manually (only at the HMI/panel);
Via communication; or
Via a digital input.
Changing to another mode is only possible if there is no active Activation Signal
(e.g.: if the device is in the “Via Digital Input Mode” and while the assigned
Digital Input is “true”, the User cannot switch to the “Manual Mode”).
