Fig. To conform to Class II restrictions, transformers must not be larger than 100 VA. A transformer that is CE certified and meets the Low Voltage Device (LVD) requirements must be used in Europe for all installations of this product. The DWM can get power from any convenient location in the 24 Vac power circuit. The 24 Vac power can come from the 24 Vac power terminals on the nearest controller or directly from a 24 Vac transformer, whichever is closer. When all wiring is complete, attach the cover of the DWM as is shown in Fig. NOTE: Make sure that the latch on the underside of the DWM engages properly.
