[ 1 ] SUPPORT REQUIREMENTS
Main Controller :
The main controller of model
505
is designed for mounting
on wood studs with three lag screws (ø 9 x 75mm). The wall
and mounting hardware must be sufficient to withstand
a 45kg
shear load
and
a 200kg withdrawal force
at each of the three
mounting screws. When using concealed wiring, a flush mounted
junction box with the necessory conduit and wirong must be
pre-installed at 1165mm from the floor.
Sub Controller :
When mounting the model
505
sub controller, the wall and mounting
hardware must be sufficient to withstand a
4.5kg shear load
.
If the PHOT-X II s 505 is to be mounted in a manner other than
what is specified in this manual or if the hardware to be used is other
than what is supplied, the support capability of the wall and the
strength of the hardware must be checked and verified to be adequate.
[ 2 ] ELECTRICAL REQUIREMENTS
Power supply :
The model
505
x-ray system is operated on a power supply of rated line voltage ±10% with a thre
wire (hot, neutral, earth) circuit, separately connected to the central distribution panel with an
over current protection device. Use a flexible cable approved by CEE (13) 52 or 53 consists of
0.75 mm
2
or 1 mm
2
conductors. Diameter of the sheath of cable should be 6 ~ 7.5 mm diameter.
Line voltage regulation should be within the range of 0 ~ 5% (for 100V, 110V, 120V type) or
0 ~ 3% (for 220V, 230V, 240V type) at rated current.
Interconnecting wiring between main controller and sub controller :
4 conductor s , 0.5 m m
2
, 300V is recommended. Maximum wire run distance is 10m.
Concealed wiring :
Route conduit and wires through wall and into (2) flush mounted junction boxes located (1)
behind the main controller and (1) behind the sub controller. Recommended heights above the
finished floor for the flush junction boxes are : 1165mm for the main controller and 1310mm
for the sub controller. Wiring done in this manner should extend 300mm beyond the wall surface
to allow sufficient wire for connections.
Note :
All connections, workmanship and materials used must comply with the local codes.
