Important
This equipment contains devices which are susceptible to
damage from static charges. Refer to
on page 17
when handling these devices.
Important
Insulated gate FET transistors are susceptible to damage
from static charges, due to their extremely high input resist-
ance. To avoid possible damage to the device during han-
dling, testing or actual operation, we recommend you fol-
low these procedures: avoid unnecessary handling; when
handling the device, pick it up by the cap, not the leads; do
not insert or remove the device while the power is on;
avoid contact with non-conductive plastic or non-conduc-
tive styrofoam.
The DC converter board and standby power supply card are colour-coded
according to their nominal input voltage. The auxiliary power supply board
is also colour-coded according to its nominal output voltage. The colours
used are as follows:
12VDC – green
24VDC – yellow
48VDC – red.
