7.8 Environmental Connections
The IDH4X and IDH4L have the capability to monitor and control enclosure environmental heating and
cooling. Typically this is used for battery mat heaters in cold environments, however the functionality may
be implemented to control enclosure fans or air conditioners. The following section will outline the details
of the controls available and will include an example of a typical battery heater mat configuration and
explanation of the settings.
7.8.1 Connecting the Battery Heater Mat Controller
Power to the heater mat is provided via a customer-supplied controller plugged into the power
outlet inside the enclosure. A cable (Alpha p/n 875-627-22) connects the controller to the ENV
(Environmental) connector on the IDH4X and IDH4L. The connection procedure is shown below.
1. Connect the 4-pin connector from the
controller cable (Alpha p/n 875-627-22) into the
base of the Heater Mat Controller.
2. Plug the controller into the power outlet.
3. Plug the Heater Mat into the controller.
4. Plug the 6-pin connector into the ENV
connector.
Once the connection has been made, Environmental Control Management can be
configured through the following tables. The Environmental Control MIB section begins at
atiMgmtSysTempMgr (1.3.6.1.4.1.926.1.3.2.4).
Status of the Environmental Control is also available on the transponder’s Web page.
