4. To remove the microSD card, push it in until the spring release pushes it partially out of the card carrier, grasp the card, pull it completely out
of the unit and store it in a static free protective case.
5. Carefully slide the card shutter back over the card carrier opening until it clicks in place. When properly closed, the shutter should not protrude
behind the mounting base.
Mounting
Mount the EC-BOS-9 in a location that allows clearance for wiring, servicing, and module removal. The following drawing shows the dimensions of an
EC-BOS-9 with option modules.
Figure 2: Mounting dimensions of the EC-BOS-9 and option modules.
Horizontal mounting (as shown) is required to achieve maximum heat dissipation and meet the operating temperature upper limit requirement. Any other
mounting orientation reduces this upper limit.
Mounting on a 35mm wide DIN rail is recommended. The controller’s unit base has a molded DIN rail slot and locking clip, as do option modules. DIN rail
mounting ensures alignment of the connectors between each device.
Up to four (4) option modules are supported. Refer to Option Module and Capacity Considerations for details.
Environmental Requirements
This product is for indoor use only, altitude to 2,000m (6,562 ft.).
For a unit mounted inside an enclosure, ensure that the enclosure is designed to keep the unit within its required operating temperature range (considering
a 24-watt dissipation by the controller). This is important if the controller is mounted inside an enclosure with other heat-producing equipment.
Ambient conditions must be within these ranges:
• Operating Temperature: -20°C to 60°C (-4°F to 140°F).
• Storage Temperature: -40°C to 85°C (-40°F to 185°F).
• Relative humidity: 5% to 95% non-condensing. Pollution Degree 2
• Supply (mains) voltage allowable voltage fluctuation +/- 10%,
Do not mount the unit:
• In an area with excessive moisture, corrosive fumes, or explosive vapors.
• Where vibration or shock is likely to occur.
• In a location subject to electrical noise, such as in the proximity of large electrical contractors, electrical machinery, welding equipment, and so on.
