Replacing the Input/Output Board
•
When the I/O board is removed any LVD fitted will disconnect:
•
If a battery disconnect LVD is fitted the battery will be disconnected when
the I/O board is removed (the load equipment will continue to operate from
the rectifiers).
•
If a load disconnect LVD is fitted then this LVD must be bridged so that the
low priority loads are not disconnected when the I/O board is removed.
Before you start you will require:
•
A PC/Laptop with
DCTools*
connected to the system controller or a web browser*
connected to the system controller via an IP network.
*See Communications Options in the System Controller Operation Handbook.
•
A replacement input/output board.
•
An anti-static wrist strap to prevent damage to the static sensitive components on the
input/output board.
•
•
An LVD bridge cable if a load disconnect LVD is fitted.
Step 1 - Bridge load disconnect LVD(s) (if fitted)
Ignore this step if there is no load disconnect LVD fitted.
