CAUTION: Remote cabling is not design for "hot-plugging". Ensure that power
is off to the electronics module when connecting the print mechanism."
Interconnect cables are keyed to prevent misconnection. Care should be
taken to assure that all three connections are correct and fully seated.
Due to the modular capability of the Epic 430 TM 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 the electronic module mounted on a chassis and the printer
mechanism 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.
