Electrical data
A.5.3.1
Mains requirements
The equipment
must be
permanently connected to the mains.
It requires a single (or double) phase mains supply with line and
neutral, 50 or 60 Hz.
Check the correct phase-neutral polarity connec-
tion at the time of installation if single phase mains
supply is available.
There is a mains connection box at the base of the column where
the power cable (not provided) has to be connected at installa-
tion time.
Mains fuses are provided on each phase. In case of single phase,
the fuse on the neutral is excluded by a jumper.
A.5.3.2
Mains voltage
The nominal mains voltage range is from 115 VAC to 250 VAC with
a tolerance of ± 10%.
The system adapts automatically to the mains voltage applied by
means of the internal electronic circuit.
The useful range is conveniently adjusted during X-ray exposure,
to take into account the mains fall during load.
A.5.3.3

A.5.3.4
Mains frequency
The mains frequency required is 50 or 60 Hz, with excursion within
the 48 to 62 Hz acceptable range.
The unit adapts to the local mains frequency, without any need
for programming.
A.5.3.5
Mains resistance
The mains supply resistance, as measured at the line input con-
nector, shall not exceed the following ranges:
VOLTAGE (VAC)
LINE RESISTENCE (OHM)
115
0.2 MAX
250
1.0 MAX
A.5.3.6
Electrical installation
The mains supply cord has to be provided and installed locally,
with termination to the electrical connecting box provided on
the front of the column.
The circuitry in the electrical connecting box is
always live: before access to it, disconnect from
the mains by means of the external mains circuit
breaker.
The length and size of the mains supply cord have to be properly
dimensioned in order not to exceed the limits foreseen on mains
supply resistance.
Recommended wire size is AWG 14.
You are recommended to supply the mains to the Orthoralix via
a dedicated magneto/thermal circuit breaker of 16 A max (with
NBJOTTVQQMZ7"$PS"NBY XJUINBJOTTVQQMZ7"$
plus (depending on local regulations) an earth leakage circuit
breaker with recommended leakage current of 30 mA.
