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.
