Earth Bonding Apart from the Type 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 Type 2 Cover printers 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 printer are for the protection of all

operators and maintenance personnel. ASM strongly recommend safety

devices are never overridden.

Type 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.

NOTE

Some of the covers can only be removed in a specific order due to the covers

interlocking with each other.
