XRB Isolator Enclosure Application Note
●The XRB3 must always be located inside an equipment enclosure.
The installation must meet the following requirements:
■ The enclosure must provide appropriate mechanical strength and ingressprotection:a. IP20 for indoor locationsb. IP54 for outdoor locations or indoor wet locations.
■ If located in a hazardous area or zone, the enclosure and interconnections must meet all certification requirements for the hazardous area or zone including wiring connections, glands, conduit, etc.
■ The enclosure design must ensure the ambient temperature inside the enclosure must not exceed 80°C even under isolator ‘fault conditions’:
▲This includes enclosure internal temperature rise from 12W of potentialheating contribution / dissipation from the XRB isolator.
◆This maximum heating contribution of 12 Watts from the isolator ‘fault condition’ occurs when 24 volts power is applied to the isolator and a short circuit load is applied on the isolator power output to the encoder.
◆The designer may not rely on external power supply limits or fusing to the XRB to avoid this fault condition as actual current draw (but not thermal heating) during normal operation can exceed the ‘faultcondition’.
▲ This includes internal temperature rise from any other equipment in the enclosure.
▲This includes the maximum expected ambient external air temperature for the enclosure which includes any external sources of enclosure heating (motor,sunshine, etc.)
■ All instructions from both the XRB isolator and XR encoder manuals for the specific hazardous location must be followed.
■ All instructions from both the XRB isolator and XR encoder installation drawing for the specific hazardous location must be followed.
