3.3 Mounting the control unit
3.3.1 Mounting the wall-mount version
Guidelines
This housing is rated IP65. It is suitable for mounting outside, but this should be above
any flood level, away from any overflow path, and away from direct sunlight
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
The mass of the mains powered unit is 1.4 kg, and the DC powered unit is 1.0 kg.
To conform with safety requirements, the wall on which the unit is mounted should be
capable of supporting four times this weight
It is not necessary, or advisable, to remove the upper part of the unit housing that
contains the LCD and keypad. There are no user serviceable parts inside. The unit must
not be modified in any way
Procedure
1. Mount the unit on a suitable wall or structure using the fixing points shown on
Figure A-1 on page 121.
2. Make the electrical connections
(see “Making electrical connections on wall-mount units” on page 13).
3.3.2 Mounting the panel version
Guidelines
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 – see Product Data Sheet IP2031 on the Mobrey brand pages at
www.emersonprocess.com for ordering information
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 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 MCU90F)
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
