High Throughput Conveyor Option
Safety Covers Where the High Throughput Conveyor (HTC) option is used, the transport rails
extend out beyond the normal printer footprint. Special safety covers have been
provided in place of the standard safety covers (see also Type 2 Covers).
NOTE
The safety panel can be adjusted to accommodate the thickness of the product.
Figure 3-10 HTC Safety Covers
The covers are fitted to the side panels to protect personnel from inadvertent
access to the board entry/exit ports.
A pair of HTC safety covers are mounted on both the left and right hand sides
of the printer. The covers have slotted holes on the two cover halves allowing
the user to set sufficient gap for the product to be moved into and out of the
printer without restriction, while still protecting the operator from potential harm.
To remove the safety cover, remove the safety cover securing screws.

Electrostatic
Protected Area
(EPA)
The EPA cover package option is available for the Type 2 Cover printer only.
Each panel on the printer is coated in a conductive layer and the panels are
electrically connected to the adjacent panel creating the Electrostatic Protected
Area. The panels are electrically grounded ensuring surface static deposition is
kept well below 100 Volts.
