Overview

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

(2)

Category II

(IEC 60664-1).

Install your DataSite unit using these installation instructions.

(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.

(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.

Mounting the Controller

Most applications require installation in an industrial enclosure to reduce the effects of electrical interference and environmental exposure. Locate your controller as far as possible from power lines, load lines, and other sources of electrical noise such as hard-contact switches, relays, and AC motor drives. For more information on proper grounding guidelines, see the Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1

You can mount the controller either horizontally or vertically on DIN rails, but horizontal mounting is recommended for thermal considerations.

Be careful of metal chips when drilling mounting holes for your controller or other equipment within the enclosure or panel. Drilled fragments that fall into the controller could cause damage.

Controller Spacing

When mounting the controller, allow 25 mm (1 in.) of space on all sides for adequate ventilation, as shown below.

DIN Rail Mounting

A small Phillips screwdriver is required for the installation or removal of the controller. The controller can be mounted to EN50022-35 x 7.5 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.

2. Loosen the two clamp screws until the clamp can slide out.

Do not remove the screws from the clamp, otherwise they will fall into the chassis.

3. Place the controller onto the DIN rail, using the rail hooks on the back of the controller.

4. Slide the clamp out while pushing the controller fully onto the DIN rail (1). When the controller is properly aligned on the DIN rail (2), slide the clamp in, so that it makes direct contact with the lower edge of the DIN rail (3).

5. Tighten the clamp screws.

Follow these steps to remove your controller from the DIN rail.

1. Loosen the two clamp screws until the clamp can slide out, taking care not to dislodge the clamp screws from the clamp.

2. Remove the controller.

Power Source Requirements

The DataSite modules (1758-FLO301, 1758-FLO302, 1758-RTU201, 1758-RTU202) must be powered by a National Electrical Code (NEC) or Canadian Electrical Code (CEC) Class 2 power source when used in locations covered by Underwriters Laboratories. In locations governed by International Electrotechnical Commission (IEC) or EN standards, a Safety Extra Low Voltage (SELV) power source must be used.

Wiring for Power Supply Input

Refer to Power Source Requirements for details on wiring.
