Dwyer FBLT - Manual (Page 2)

WARNING:
A voltage potential between the ground wire of the unit and the ground
of other equipment can lead to electrolytic corrosion. Always ensure the
grounding system provides an equipotential between the transmitter and
the earthing ground connection. Avoid using the power system protective
ground since this will often have a significant potential difference to the
transmitter ground. Also note that dissimiliar metals in the ground system
may cause electrolysis corrosion of the transmitter or other components
in the ground system.
During installation, connect a voltmeter or ammeter between the shield
ground wire and the grounding connection. If there is a measurable
voltage or current electrolytic corrosion may be a serious possibility. If
there is a potential difference then some isolation system will be
required. Improper grounding may lead to damage or poor signal
integrity.
MAINTENANCE/REPAIR
Upon final installation of the Series FBLT, no routine maintenance is
required. The Series FBLT is not field serviceable and should be returned
if repair is needed (field repair should not be attempted and may void
warranty).
WARRANTY/RETURN
Refer to “Terms and Conditions of Sales” in our catalog and on our
website. Contact customer service to receive a Return Goods
Authorization number before shipping the product back for repair. Be
sure to include a brief description of the problem plus any additional
application notes.
