Working on the system
■ Isolate the system from the power sup-
ply (e.g. by removing the separate fuse
or by means of a mains isolator) and
check that it is no longer 'live'.
Note
In addition to the control circuit, there
may be several power circuits.

can lead to fatal injury due to
electric shock. Some compo-
nents on the PCBs will remain
'live' even after the power sup-

Prior to removing equipment
covers, wait at least 30 sec-
onds to allow the voltage to dis-
sipate.
