2.7 MOUNTING
The instrument has four (4) 4.2mm (0.165in) diameter mounting holes on 108mm x 50mm (4.25in
x 1.97in) centres. These mounting holes are segregated from the electronics by partitioning in the
box moulding which may thus be secured to any surface using only two screws without affecting
the sealing.

2.8 ELECTRICAL AND EMC CONSIDERATIONS
The OD2 meets the following requirements
Emissions
EN61000-6-3, specifically EN 55022 Conducted Emissions Class B and EN55022 Radiated Emis -
sions Class B.
Susceptibility
EN610004-3 Radiated Immunity 1.4GHz to 2.7GHz 3V/m
EN610004-3 Radiated Immunity 80MHz to 1GHz 10V/m
ESD
EN610004-4-: ±4kV contact and ±8kV air
Installation Guidance
The type of cabling used to connect the OD2 depends on the electrical environment. In a clean
environment unscreened twisted pairs provide a low cost suitable connection, in an environment
where electrical noise is higher, such as installation inside a machine or on the factory floor it is
advised to use screened cables.
Do not route power cables close to the OD2 or any interconnecting cables as these may cause a
disturbance in the performance. Avoid as much as possible mounting the OD2 close to any kind of
switch gear or other equipments that can produce high intensity electrical or magnetic fields.
Wherever possible keep cables below 3m in length.
