1.  Safety Regulations 

 
VERY IMPORTANT: Instruments and components supplied by npi electronic are NOT 
intended for clinical use or medical purposes (e.g. for diagnosis or treatment of humans), 
or for any other life-supporting system. npi electronic disclaims any warranties for such 
purpose.  Equipment  supplied  by  npi  electronic  must  be  operated  only  by  selected, 
trained  and  adequately  instructed  personnel.  For  details  please  consult  the GENERAL 
TERMS OF DELIVERY AND CONDITIONS OF BUSINESS of npi electronic, D-71732 
Tamm, Germany.
 
 
1)

 

GENERAL:  This  system  is  designed  for  use  in  scientific  laboratories  and  must  be 
operated only by trained staff. General safety regulations for operating electrical devices 
should be followed. 

 
2)

 

AC MAINS CONNECTION: While working with the npi systems, always adhere to the 
appropriate  safety  measures  for  handling  electronic  devices.  Before  using  any  device 
please read manuals and instructions carefully. 
The  device  is  to  be  operated  only  at  115/230  Volt  60/50  Hz  AC.  Please  check  for 
appropriate line voltage before connecting any system to mains. 
Always  use  a  three-wire  line  cord  and  a  mains  power-plug  with  a  protection  contact 
connected to ground (protective earth).  
Before opening the cabinet, unplug the instrument. 
Unplug  the  instrument  when  replacing  the  fuse  or  changing  line  voltage.  Replace  fuse 
only with an appropriate specified type. 

 
3)

 

STATIC  ELECTRICITY:  Electronic  equipment  is  sensitive  to  static  discharges.  Some 
devices such as sensor inputs are equipped with very sensitive FET amplifiers, which can 
be damaged by electrostatic charge and must therefore be handled with care. Electrostatic 
discharge  can  be  avoided  by  touching  a  grounded  metal  surface  when  changing  or 
adjusting  sensors.  Always  turn  power  off  when  adding  or  removing  modules, 
connecting  or  disconnecting  sensors,  headstages  or  other  components  from  the 
instrument or 19” cabinet.
 

 
4)

 

TEMPERATURE  DRIFT  /  WARM-UP  TIME:  All  analog  electronic  systems  are 
sensitive to temperature changes. Therefore, all electronic instruments containing analog 
circuits should be used only in a warmed-up condition (i.e. after internal temperature has 
reached  steady-state  values).  In  most  cases  a  warm-up  period  of  20-30  minutes  is 
sufficient. 

 
5)

 

HANDLING:  Please  protect  the  device  from  moisture,  heat,  radiation  and  corrosive 
chemicals.
