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 
by trained staff only. 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.
