LCD Meter Rotation In addition to housing rotation, the optional LCD meter can be rotated in
90-degree increments. To rotate the LCD meter, remove the front housing
cover (this may require a wrench). Squeeze the two tabs located on the sides
of the LCD meter and lift the meter out. Rotate the LCD meter to the desired
direction and snap back into place. Replace the front housing cover and
tighten.
NOTE
The jumpers may come loose while removing the LCD meter. Be sure that
they are fully seated in the housing before snapping the LCD meter into place.
Consider RPS
Positioning
When installing the optional Remote Power Supply (RPS), position the solar
panel so that it has the best possible access to sunlight throughout the day. If
direct sunlight access is not available, indirect (reflected) sunlight sources can
be used.

Signal Wiring Grounding
Do not run signal wiring in conduit or open trays with power wiring, or near
heavy electrical equipment.
HAZARDOUS
LOCATIONS
The Rosemount 753R and any attached devices must be installed according
to the guidelines and certifications listed in their respective user manuals.
NOTE
Once a device labeled with multiple approvals is installed, it should not be
reinstalled using any other approval type(s). Permanently mark the
certification label to distinguish the installed approval type from unused
approval types.
Grounding the Wireless
Indicator Case
Always ground the wireless indicator case in accordance with national and
local electrical codes. The most effective wireless indicator case grounding
method is a direct connection to earth ground with minimal impedance.
Methods for grounding the wireless indicator case include:
• Internal Ground Connection : The Internal Ground Connection screw
is inside the terminal side of the electronics housing. The screw is
identified by a ground symbol ( ), and is standard on all Model 753R
Series indicators.
DECOMMISSIONING
PROCEDURES
Please be familiar with all warnings before attempting to decommission your
753R. See “Warnings” on page 2-1.
Explosions can result in death or serious injury.
• Do not remove the wireless indicator covers in explosive environments when the
circuit is live.
• Before connecting a communicator in an explosive atmosphere, make sure the
instrumentsin the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
• Verify that the operating atmosphere of the wireless indicator is consistent with the
appropriate hazardous locations certifications.
Electrical shock can result in death or serious injury.
• Avoid contact with the leads and terminals
