HIGH VOLTAGE PROTECTION
Access Where incoming supply voltages are present, protection is afforded by con-
trolling access to the enclosures that house the supply. The printer is fitted with
a mains isolator switch that cuts power to all circuits located beyond the switch.
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 Apart from EPA and metal covers printers, which use the covers to make the
bond, all external metal surfaces are mechanically and electrically bonded to
the printer 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.

1. Close down the printer software.
2. Switch the mains isolator to the OFF position.
3. Pull the lockout tab out.
