1.4.1 General Safety Warnings
WARNING:
• Always connect all GES components, except those inside the
MR imaging room, to the isolation transformer.
Never connect
components directly to mains electricity supply, which may
result in physical injury or equipment damage.
• Never deviate from supported configurations and never connect
non-EGI components to the isolation transformer or to other EGI
components.
All EGI components must be installed and
