8 Service, Accessories & Spares

8.1 Rectifier replacement

If a faulty rectifier is to be replaced simply unscrew the two front panel fixings on the rectifier front panel and withdraw the rectifier from the shelf. A replacement rectifier can then be inserted directly into the shelf and will start-up automatically.

Note – The rectifiers are “hot plugable” and therefore can be replaced without turning the system off.

8.2 Controller replacement

If the alarm card is to be replaced simply unscrew the two front panel fixings and withdraw the module from the shelf. A replacement module can then be inserted directly into the shelf and will start-up automatically.

Note - with the module removed the system will revert to default rectifier conditions of 54.5V. Some alarms and all control functions will be unavailable including battery monitoring.
