Specifications for Electrical Installation
These specifications are based on the MEIGaN (Medical electrical installation
guidance notes).

Power rating
The input line voltage depends on the local electrical distribution system.
Allowable input voltage fluctuation requirement: ±10 %.
Mode of operation: Continuous operation with intermittent loading - Needs
waiting time (at least 60 times the exposure time) before the next
vatech A9 (Model: PHT-30CSS)
This equipment must be connected to a grounded outlet to
fulfill the safety provisions specified in IEC 60364: the 2
edition (2006).
Both PC and equipment must use the same power line if
they are connected to an MPSO.
Whenever not possible, use different power outlets for each
device. If a multiple portable socket outlet (MPSO) must be
used, ensure that the PC and equipment are connected to
the same MPSO.
Use a dedicated power outlet for the power cord. Failure to
do so may result in unstable system operation caused by
power fluctuations.
It is strongly recommended that you install an AVR. An AVR
(automatic voltage regulator) for a continuous operation in
the event of power fluctuation.
