4.1 Installation requirements
NOTICE
High temperatures reduce the life-time of the display.
‣To avoid heat accumulation, ensure the device is sufficiently cooled.
‣Do not operate the device in the upper temperature range over a longer period of time.
The process indicator is designed for use in a panel.
The orientation is determined by the legibility of the display. The connections and outputs are
provided on the rear. The cables are connected via coded terminals.
Operating temperature range:
Non-Ex/Ex devices: –20 to 60 °C (–4 to 140 °F)
UL devices: –20 to 50 °C (–4 to 122 °F)
4.2 Dimensions
Observe the installation depth of approx. 150 mm (5.91 in) for the device incl. terminals and
fastening clips.
In the case of devices with an Ex approval, the Ex frame is required and an installation depth
of 175 mm (6.89 in) must be taken into consideration. For more dimensions please refer to
the "Technical data" section in the Operating Instructions.

Mounting RIA45
8 Endress+Hauser
• Panel cutout: 92 mm (3.62 in) x 45 mm (1.77 in).
• Panel thickness: max. 26 mm (1 in).
• Max. viewing angle range: 45° to the left and right from the central display axis.
• If the devices are arranged horizontally beside one another in the X-direction, or arranged
vertically on top of one another in the Y-direction, the mechanical distance (specified by the
housing and front section) must be observed.
4.3 Mounting procedure
The necessary panel cutout is 92 mm (3.62 in) x 45 mm (1.77 in)

 1 Installation in a panel
1. Screw the threaded rods (item 1) into the positions provided on the mounting frame
(item 2). Four opposing screw positions (item 3/4) are available for this purpose.
2. Push the device through the panel cutout from the front.
3. To secure the casing in the panel, hold the device level and push the mounting frame
(item 2), with the threaded rods screwed in, over the casing until the frame locks into
position (1).
4. Then tighten the threaded rods to fix the device in place (2.).
5. For the Ex option, mount the spacer (item 6) for the terminals.
To remove the device, the mounting frame can be unlocked at the locking elements (item 5)
and then removed.

4.4 Post-installation check
• Is the seal undamaged?
• Is the mounting frame securely fastened on the housing of the device?
• Are the threaded rods properly tightened?
• Is the device located in the center of the panel cutout?
• Is the spacer mounted (Ex option)?
5 Wiring
LWARNING
Danger! Electric voltage!
‣The entire connection of the device must take place while the device is de-energized.
‣The protective ground connection must be established before all other connections. If the
protective ground is disconnected, this can be a source of danger.
‣Before commissioning the device, make sure that the supply voltage matches the voltage
specifications on the nameplate.
‣Provide suitable switch or circuit breaker in building installation. This switch must be
provided close to the device (within easy reach) and marked as a circuit breaker.
‣An overcurrent protection element (rated current ≤ 10 A) is required for the power cable.
• Observe the terminal designation on the front of the device.
• The mixed connection of safety extra-low voltage and dangerous contact voltage to the
relay is permitted.
5.1 Electrical connection
A loop power supply (LPS) is provided for every input. The loop power supply is primarily
designed to supply power to 2-wire sensors and is galvanically isolated from the system and
the outputs.
