
To assure line voltage quality, a separate 3-core
grounded power cable connected directly to the central
distribution panel with an over-current circuit breaker
rated for 20A must be used.

Maximally allowed deviation of the tube voltage/tube
current/exposure time:
Tube Voltage (kVp) ± 10 %/Tube Current (mA) ±
20 %/Exposure Time (s) ± (5 % + 50 ms) according to
IEC 60601-2-63.

The mains resistance should not exceed 0.045 ohms at
100 V and 0.19 ohm at 240 V.
