Rectifiers
Transient protective devices are fitted with alarm contacts and visual indicators. Monitor the
status of all externally installed transient protective devices either by:
•
Connection of the alarm contacts to one of the Digital Inputs on the supervisory module
(preferred option) or to the building management system. See Installing External Alarm
and User Digital Inputs Cabling for details of Digital Inputs.
•
Regular inspection of the visual indicators.
The alarm signal lines of the external transient protective devices must be isolated from the
ac supply (by voltage-free relay contacts) before connecting these signal lines to the
supervisory module.
For information on monitoring and replacing MOVs see details on page
