Your WI-I/O 9-L-R receiver unit has the following components and terminal connections:
In order to comply with Electrical Safety Regulations, this module must be installed in an Electrical AND
Fire enclosure. This enclosure may be a single or multiple enclosures. Access to the module is to be
made by a Service Person only.
In order to comply with Electrical Safety Standards, when connecting SELV AND voltages which are
greater than SELV (30VAC or 60VDC) together, then Relay Output 2 must NOT be used in order to
provide sufficient isolation between the outputs
