Safety Precautions

To maintain safe operating conditions for the 4072A/4073A tester, observe the following earthquake, fire,
electrical, and chemical safety precautions.

Earthquake

To prevent the system cabinet from tipping over in an earthquake, fix the system cabinet to the floor as shown in
figure 2-5. (a). Use suitable metal fittings to fix the system cabinet, taking into account the system cabinet screw
holes and floor conditions.
For example, figure 2-5. (b) shows the dimensions for suitable metal fittings. These metal fittings and screws are
not furnished with the system. Please prepare these parts. The metal fittings are appropriate for the Uniform
Building Code (UBC) Zone 4.
The system cabinet's center of gravity is the center of the system cabinet, as shown in figure 2-6.. The center of
gravity may be changed when reconfigurating any instruments in the system cabinet.
