Earth Bonding Apart from the Style 3, 4 and 5 covers printers, which use metal 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 they are secured tightly and cleanly,
when replaced.
NOTE
The EPA cover package option is available for the Style 2 Cover machine only.
Its covers are bonded through a series clips and sprung contact studs. The
covers themselves have an electrically conductive conformal coating to dissi-
pate static electricity. For the Electrostatic Protected Area to work effectively, all
fixings are to be kept clean, all panels must be fitted correctly, and the printhead
cover closed.
Safety Interlocks The safety features designed into the machine are for the protection of all
operators and maintenance personnel. ASM strongly recommend safety
devices are never overridden.
Style 1 Covers In order to protect personnel and prevent damage, eight covers are fitted to the
printer. The upper part of the printer is protected by the sliding printhead cover,
one rear lifting printhead cover and two upper side panels which house the
control switches.
