Power connector
Warning:
High voltage may be present on the power connectors.
Before plugging or unplugging a controller (in/from the rack case), connecting or
disconnecting the power cables (for the housed format) or touching the controller,
turn off all the power supplies
and wait 10 minutes
to allow the internal DC bus
capacitors
to
discharge.
Always connect the ground prior to any other
connection
.
Caution:
This connector must be handled in an ESD protected environment, only.
Remark:
The power cables connected to the DSC2P must be shielded (see
§3.7.1
).
3.5.1
Connector JC15: Rack format, power supply input
You have the possibility to power the DSC2Ps:
3.5.1.1
With an ETEL power supply
The most practical way is to use an ETEL power supply (with an ETEL back panel) because all the necessary
connections are already realized according to the table below. Just plug the power module and the controller
at the right place (refer to the
'DSO-RAC2 Hardware Manual'
for more information).
3.5.1.2
With a power supply from the market
If you are using a power supply from the market, it must include: an UL recognized filter for the EMC (refer to
the 89/336/EEC directive), UL recognized MOVs (Epcos, SIOV-S14K320G5S5 (Vclamp=840V) for the power
input and a SIOV-S14K275G5S5 (Vclamp=710V) for the auxiliary input, or equivalent (CCN XUHT2)), an
inrush limiter (according to the size of the capacitor bank) and UL listed fuses (Little fuse, KLKD, F20AH
600VDC or equivalent on the power input and a F2AL, 250V on the auxiliary input).
The signal sent to the DSC2P pin d14 (INRUSH) has to be:
•
+15VDC (loading or error): the power supply delivers the current to load the DSC2P DC bus capacitors
(+15VDC between d14 (inrush) and z16 (GNDpwr)).
•
0V (ready): the power supply has finished to load the DSC2P DC bus capacitors (shorted to z16
(GNDpwr)).
For safety reasons, always connect first the protective earth (PE) to the dedicated pins!
