operating temperature range.
Before Applying Power
Verify that all safety precautions are taken. The power cable inlet of the instrument serves 
as a device to disconnect from the mains in case of hazard. The instrument must be 
positioned so that the operator can easily access the power cable inlet. When the 
instrument is rack mounted the rack must be provided with an easily accessible mains 
switch.

electrical protective earth ground. The instrument must be connected to the ac power 
mains through a grounded power cable, with the ground wire firmly connected to an 
electrical ground (safety ground) at the power outlet. Any interruption of the protective 
(grounding) conductor or disconnection of the protective earth terminal will cause a 
potential shock hazard that could result in personal injury.
