Environmental Requirements
Note the following requirements for the EC-BOS-6
AX
mounting location:
•
This product is intended for indoor use only. Do not expose the unit to ambient conditions outside of the
range of 0ºC (32º F) to 50ºC (122º F) and relative humidity outside the range 5% to 95% non-condensing
(pollution degree 1).
•
If mounting inside an enclosure, that enclosure should be designed to keep the unit within its required
operating range considering a 20-watt dissipation by the controller. This is especially important if the
controller is mounted inside an enclosure with other heat producing equipment.
•
Do not mount the unit:
–
in an area where excessive moisture, corrosive fumes, or explosive vapors are present.
–
where vibration or shock is likely to occur.
–
in a location subject to electrical noise. This includes the proximity of large electrical contractors,
electrical machinery, welding equipment, and spark igniters.
Physical Mounting
The following information applies about physically mounting the unit.
•
You can mount the EC-BOS-6
AX
in any orientation. It it not necessary to remove the cover before
mounting.
•
Mounting on a 35mm wide DIN rail is recommended. The EC-BOS-6
AX
unit base has a molded DIN rail
slot and locking clip, as does the power module and the I/O expansion modules. Mounting on a DIN rail
ensures accurate alignment of connectors between all modules.
•
If DIN rail mounting is impractical, you can use screws in mounting tabs on the EC-BOS-6
AX
, then in any
end-connected accessory (EC-NPB-PWR, etc.). Tab dimensions are on page 26 of this document.
The following procedure provides step-by-step DIN rail mounting instructions for the EC-BOS-6
AX
.
Note
Mount the EC-BOS-6
AX
prior to mounting any accessory items (24V power module, etc.).
Procedure 1 To mount on DIN rail
Step 1
Securely install the DIN rail using at least two screws, near both ends of the rail.
Step 2
Position the EC-BOS-6
AX
on the rail, tilting to hook DIN rail tabs over one edge of the DIN rail
( Figure 1 on page 6 ).
Step 3
Use a screwdriver to pry down the plastic locking clip, and push down and in on the EC-BOS-6
AX
, to
force the locking clip to snap over the other edge of the DIN rail.
Step 4
Mount any accessory item onto the DIN rail in the same manner.
