3.2.2 Installation guidelines for the panel mount version
Figure 3-1: Panel Mount
• This housing is rated IP40 and is designed for panel mounting in a weatherproof
environment. An optional fascia overlay hood is available which improves the IP rating
to IP65.
• Do not mount the control unit on a structure that is subject to vibration, or in a position
where damage may be caused by impact, thermal stress, or liquid ingress.
• Where three of more units are fitted in the same cabinet or panel, ensure that there is
adequate air circulation to aid cooling. It is recommended that an air circulation fan be
fitted.
• The control unit requires at least 6.5-in. (165 mm) clearance behind the mounting
panel to avoid cable fouling.
• After mounting the control unit, all wiring is made at the rear of the unit using the two
part terminal blocks provided. (A pre-wired data download socket suitable for front
panel mounting is provided on the Rosemount 3493 Control Unit).
• Mount the control unit on a panel with thickness 1.5 to 10 mm, ensuring the panel is
strong enough to support the 2.6 lb. (1.2 kg) weight of the unit.
• Ensuring there is enough clearance behind the chosen position in the panel (6.5-
in./165 mm minimum), cut a horizontal slot 5.43-in. (138 mm) long by 2.68-in. (68
mm) high in the panel and remove any rough edges.
