finally I installed the OneFive laser, the Smaract motors of the laser and the Arduino Peltier controller of the laser on the UPS plug.
the power "seen" by the UPS is 0W, perharps because the used power is below 100W.
the UPS says it can last 385mn (> 6h) in case of power shut down.
I had to do 10mm step at 10mm/s speed on CH0 of the Smaract motors to get back the laser modelock.
then, I put back the CH0 position at +140µm and the CH2 position at -177.8µm on the Smaract motor.
the present level measured by the laser amplifier is 3.05mW after the power ON of the laser @ CH0=0µm
the level measured by the laser amplifier is 3.012mW after the power ON of the laser @ CH0=+140µm
the level measured by the laser amplifier is 3.125mW after the power ON of the laser @ CH0=+140µm when we switch ON the preamplifier
then, we are able to check the laser repetition rate @ 33.383MHz measured by the amplifier software.

Jean-Noel Cayla installed several days ago a Eaton 9PX 11kVA UPS inside the Igloo, outside of the ThomX bunker
and I asked him to place only 1 UPS plug on the wall close to the FP-cavity to supply only the NKT/OneFive oscillator and the Smaract laser cavity motors.
I checked that if I plug a device on this UPS plug, I'm able to follow the power, used by the device, on the UPS monitoring screen.
thus, this morning, I plan to switch off the laser oscillator and move its power cable from a standard plug to the UPS plug and test if we are able to find back the previous performances of the locking.
the present Smaract motor positions are : CH0 => +140µm / CH2 => -177.8µm
as unpowering the motor will put the read position at 0µm, I first go back to 0µm for both channel.
I will put them back at their original values after I plug the motors back to UPS.
