Environmental Requirements

Note the following requirements for the WEB/CP-700 mounting location:
• 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, plus dissipation from any other devices installed in the same enclosure.
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 with excessive moisture, corrosive fumes, or explosive vapors.
— 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, spark igniters, and variable frequency drives.

Physical Mounting

The following information applies about physically mounting the unit.
• You can mount the WEB/CP-700 in any orientation. It it not necessary to remove the cover before mounting.
• Mounting on a 35mm wide DIN rail is recommended. The WEB/CP-700 unit base has a molded DIN rail slot and locking clip,
as does the NPB-PWR-UN-H power supply module and any I/O expansion modules. Mounting on a DIN rail ensures accurate
alignment of connectors between all modules.
• If DIN rail mounting is impractical, use screws in mounting tabs on the NPB-PWR-UN-H module and the WEB/CP-700, as well
as any end-connected accessory. Tab mounting dimensions are on the last page of this document.
