iWorx® HPU2502-025, Effective: April 12, 2011 5© 2011 Taco Electronic Solutions, Inc.• Peripheral devices, such as sensors, actuators, etc.• Cabling, cabling raceway, and fittings necessary to connect this equipment to the power source, FTT-10A networkand peripheral devices.Equipment LocationAbide by all warnings regarding equipment location provided earlier in this document.Optimally, the equipment should be installed within a secure enclosure.If the equipment is to be installed outdoors, it must be contained within a protective enclosure. The enclosure mustmaintain internal temperature and humidity within the ranges specified for this equipment.The equipment must be installed within 500 feet of all input peripherals (smoke detectors, sensors, etc.) that will beconnected to the equipment.Selecting a Power SourceThis equipment requires a UL recognized Class 2 external power source (not supplied) to operate. The controllerpower input requires a voltage of 24 Volts AC.To calculate power source current requirements, add the power consumption of all peripheral devices to that of thecontroller.The controller and sensor power supplies can use the same power source. If both are using the same power source,the loads must have EMF protection. This protection can be integral to the load, or installed in the 24 VAC wiring acrossthe load’s coil.To provide necessary RFI and transient protection, the controller’s ground (GND) pin (T40) must be connected to earthground or the earth ground of the packaged unit’s enclosure ground. Failure to properly ground the controller maycause it to exceed FCC limits. Excessive noise could also produce inaccurate sensor data. The power source must becapable of operating with this connection to ground.INSTALLATIONWarning: Electrical shock hazard. To prevent electrical shock or equipment damage, disconnect ALLpower sources to controllers and loads before installing or servicing this equipment or modifying any wir-ing.Mounting the Device1.Select a mounting location. Enclosure mounting is recommended.2.Hold the controller on the panel you wish to mount it on. With a marker or pencil mark the mounting locations onthe panel.3.Using a small drill bit pre-drill the mounting holes.4.Using two #6 pan head screws, mount the controller to the panel.5.Wire the controller (See Routing Cabling to the Device).
