Planmeca Intra X-ray unit 3
PRE-INSTALLATION REQUIREMENTS
Installation manual
Internal mains fuse ratings
The Planmeca Intra X-ray unit is equipped with dual mains fuses (live and neutral). However, in
some areas it is not allowed to have a fuse in the neutral wire. The neutral fuse is optionally
bypassed at the factory, in which case the X-ray unit is equipped with one mains fuse.
The ratings for the internal mains fuses are:
• units with 100V~ or 110-115V~ voltage setting: 15AT, 250V, slow blow
(6.3x32mm)
(special fuse, manufacturer
Bussmann, type MDA)
• units with 220-240V~ voltage setting: 8AT, 250V, slow blow
(6.3x32mm)
(special fuse, manufacturer
Bussmann, type MDA)
External mains fuse recommendation
The recommendation for the external mains fuses are:
• units with 100V~ or 115V~ voltage setting: 16A, time lag
• units with 220-240V~ voltage setting: 10A, time lag
No other equipment should be connected to the same fused mains line as the X-ray unit. In some
countries an additional external fault current guard is also required.
Grounding
The Planmeca Intra X-ray unit must always be connected to a grounded outlet to fulfill the safety
directives stated.
Power consumption
The idle power consumption is less than 30VA. Maximum power consumption is 1000VA and
occurs during the exposure (maximum exposure time is 3.2 seconds).
