On TR (axial) models this box is located at the end of a 600mm long flexible conduit which hangs underneath and is fixed to a convenient surface by the installer. These units will require bottom access to complete wiring. On TRM (mixed flow) and TR (centrifugal) models the box is located on the fan plate or motor bridge inside the cowl. On these units it will be necessary to remove the cowl to gain access. When wiring in the unit take care to avoid rotating components and also gravity shutters. 20mm holes are provided in the fan base plate to bring wiring out from inside the building. onnection details heck that the electrical supply is compatible with the unit (see unit rating plate). onnection details are supplied with speed controls. ll wiring must be carried out in accordance with regulations for electrical installations and comply with the requirements of the local supply authority. Ensure that the direction of rotation is correct. Single phase units are checked during manufacture for correct rotation. Three phase units must be tested on site and, if incorrect, interchange any two supply leads to reverse impeller direction

The enclosures for ES1-3 and ES1-6 are rated to IP45 with the ES1-10 rated at IP54. ll controllers meet LVD and EM directives for safety and electromagnetic compatibility. Please note: The mains power supply to the controller must be appropriately sized and installed via a local isolation switch (by others). The isolator must also accommodate the switched live (if used). The mains supply from the ecosmart controller to the fan must be appropriately sized, not exceeding 25 metres and must be a screened power cable, earthed at both ends. four point glanding plate is formed from the base of the control and in order to main EM compliance, a Zerohm EM glanding kit is supplied. n isolator should be located adjacent to the fan. ontra and run and standby fans will require two controls, one for each fan. ll integrated sensors plug directly into the control panel.

14 INVERTER SPEED ONTROL DIMENSIONS (MM) Front View These are a range of frequency inverters for controlling the speed of 3 phase motors. Standard range are 400V 3 phase input units covering motor rating from 0.75kW to kw. Higher ratings and single phase input models are available upon request. The inverters are microprocessor controlled and use state of the art Insulated Gate ipolar Transistor (IGT) technology. This makes them reliable and versatile. special pulse-width modulation method with selectable pulse frequency permits quiet motor operation. omprehensive protective functions provide excellent inverter and motor protection. The inverters default factory settings, is ideal for a large range of simple motor control applications. The inverters can also be used for more advanced motor control applications via its comprehensive parameter lists. The inverters can be used in both stand alone applications as well as being integrated into utomation systems.

15 ONSULTNTS SPEIFITION FN DESRIPTION The Roof mounted extract/supply fans shall be located in the positions indicated on the drawings and in accordance with the relevant fan schedule. It shall be a low profile cowl manufactured in flame retardant GRP. The fan shall be of the Terminator type and shall be supplied complete with backdraught shutters, birdguard, purlin box curb, hand guard, specific details of the curb and and purlin to be confirmed by the main contractor. EOSMRT SYSTEM OPERTION The Ecosmart controls will enable the unit to automatically vary its speed as it receives signals from one of the interconnected sensors. When the signal is received the fan shall either increase speed gradually until the required level is achieved or it will work on a trickle and boost principle. This will then move the fan duty point from trickle/background ventilation rate to the required boost ventilation rate. oth the trickle and boost rates are infinitely variable, easy to adjust and remove the need of a main balancing damper. The mechanical contractor shall make due allowance for supporting the fan via the provision of purpose made trimmers between purlin. The trimmers shall be sized to adequately support the weight of the fans. The Fan unit shall have a 3 year warranty, first year parts and labour the remainder parts only. Ecosmart Terminator shall have a 5 year warranty, first year parts and labour the remainder parts only. 2. MS INTERFES The fan unit can be provided with the following integrated MS interfaces 0-10 volt contacts to provide a full MS interface. This will enable the following functions:- Switch the unit on/off. Switch from low speed to high speed. Full speed control facility. The unit and ancillaries shall be of the Terminator type as manufactured by Nuaire Ltd. 2 No. Volt free contacts to provide fan run and failure indication to provide system status. ONTROL SPEIFITION The fan unit can be supplied with one of the following control options:- 1. Ecosmart controls (3 phase only) The compact Ecosmart control system complete with all necessary controls to facilitate the operation of the ventilation system. It shall be come complete with an integral factory fitted Ecosmart P which will control the fan unit within the desired design parameters and provide the interface between all external control devices and the unit itself.
