Environmental Specifications
The following table lists the environmental specifications that apply to the Terminator
modules. Be sure to check the specifications of the controller you are using. Also refer to
the appropriate I/O module specifications, mentioned in earlier chapters, for the temperature
derating curves for the specific module.
Power
The power source must be capable of supplying voltage and current complying with the base
power supply specifications.
Agency Approvals
Some applications require agency approvals. Typical agency approvals which your
application may require are:
•
UL (Underwriters’ Laboratories, Inc.)
•
CSA (Canadian Standards Association)
•
FM (Factory Mutual Research Corporation)
•
CUL (Canadian Underwriters’ Laboratories, Inc.)

*Equipment will operate at low humidity. However, static electricity problems occur much
more frequently at lower humidity levels. Make sure you take adequate precautions when
you touch the equipment. Consider using ground straps, anti-static floor coverings, etc. if
you use the equipment in low humidity environments.
