I can safely turn off FEUs voltages and FEU fans used for the RTPC
and FMT.

<div class="">There is another fan used to suction out the Helium
leaked out of RTPC. As long as the RTPC is outside the solenoid,
I think there is no issue to turn off that fan. But when the
RTPC is inside the solenoid, either Bob or Sebastian could
answer what can we do.<br class="">

the cross chatter - when you say “SVT
cart”, do you mean the CVT insertion cart?
As Jiwan points out, there are FEU LV and
cooling fan supplies, among other things,
on the latter. We may have to power down
the FEUs safely.<br class="">
