Epic 430 Grounding
Due to the modular capability of the E430 printer, special considerations
should be taken to ensure the modules are commonly grounded for immunity
to external electrical faults such as ESD, magnetic transients, and radio
frequency interference.
Mounting tabs are provided on the electronic module and printer mechanism
to make frame ground connections during installation. In addition, when the
electronic module and print mechanism are separated, such as when the
electronic module mounted on a chassis and the printer mechanism is
mounted on a door, the interconnecting cables may pass across potentially
un-bonded boundaries. In this case it is important that chassis and door are
conductively bonded by metal hinges or braid to maintain a common frame
ground connection between modules. Optimum installations provide a
continuous grounded surface all along the interconnecting cables between
modules.
Warning: Remote cabling is not designed for "hot-
plugging". Ensure that power is off to the electronics
module when connecting to the print mechanism.
