HIGH VOLTAGE PROTECTION
Mechanisms The machine incorporates Class 1 electrical protection according to the IEC 536
requirement 1:1993.
All machines prior to shipment undergo electrical safety tests as described in
EN60204-1 (1997) Section 19:
• 19.2 Continuity of the protective bonding circuit
• 19.3 Insulation resistance test
With the exception of the optional Onboard Suction Filtration Unit, machine
mechanisms are powered by voltages less than 50V.
NOTE
Refer to Machine Preparation chapter (Machine Relocation section) for infor-
mation on Vacuum Filtration Unit checks.
Access Where incoming supply voltages are present, protection is afforded by control-
ling access to the enclosures that house the supply. The machine is fitted with
a mains isolator switch that cuts power to all circuits located beyond the switch
on both incoming and outgoing power terminals. The isolator switch is located
at the front of the machine.
Hazard Warning
Labels
Hazard warning labels are placed on the outside of enclosures where danger-
ous voltage (100V-240V) terminations are present within.
Earth Bonding All external metal surfaces are mechanically and electrically bonded to the
machine earth point. The bonding wire used is identified by its green and yellow
insulation and is commonly used to earth bond throughout. Care should be
taken when removing these links that when they are replaced they are secured
tightly and cleanly.
