20 Installing the Controller
Mounting the Controller
DataSite controllers are suitable for use in an industrial environment when
installed in accordance with these instructions. Specifically, this equipment is
intended for use in clean, dry environments (Pollution degree 2
(1)
) and to
circuits not exceeding Over Voltage Category II
(2)
(IEC 60664-1).

DIN Rail Mounting
You can mount the controller either horizontally or vertically on DIN rails,
but horizontal mounting is recommended for thermal considerations. You
need a small Phillips head screwdriver for the installation or removal of the
controller. You can mount the controller on EN50022-35x7.5 DIN rails.
Follow these steps to install your controller on the DIN rail.
1. Mount your DIN rail.
Make sure that the placement of the controller on the DIN rail meets
the recommended spacing requirements. See
Controller Spacing on page
19 .
2. Loosen the two clamp screws until the clamp can slide out.
3. Place the controller onto the DIN rail, using the rail hooks on the back
of the controller.
(1) Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that
occasionally a temporary conductivity caused by condensation shall be expected.
ATTENTION
Electrostatic discharge can damage semiconductor devices
inside the controller. Do not touch the connector pins or other
sensitive areas.
(2) Over Voltage Category II is the load level section of the electrical distribution system. At this level transient
voltages are controlled and do not exceed the impulse voltage capability of the product’s insulation.
(3)
Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC)
designations.
IMPORTANT
Do not remove the screws from the clamp, otherwise they will
drop into the chassis.
