Page 7: Mounting
Mounting Alarm EP2 must be mounted on a vertical, fixed and non-vibrating surface with screws through the deep screw holes in each corner of the box. Please also pay attention to the section on Safety Instructions. Overview of Terminals on 230V Model Terminal No. - Page 8 Electrical Connection 230V Model Constant voltage 230V AC must be connected to terminal L and N. Operating Signal (Start monitoring) can be phase (L) or a potential free contact (low voltage), which connects when the equipment that should be monitored, is turned on. 9V battery must be connected to the battery clip. Operating Signal Phase: Constant voltage on L and N, phase on M when monitoring is to begin, e.g.
- Page 9 USB connection for control/setting and possible software updating Note: In 24V model of VentilationAlarm EP2 terminal L (1), N (3) or M (2) is not available since operating signal on model 24V must be connected to terminal 15 and 16. Supply voltage must be connected to terminal 17 og 18.
- Page 10 Electrical Connection 24V Model 0V must be connected to terminal 17 and 24V AC or 24V DC to terminal 18. Operating signal (Start monitoring) is to be connected to the potential free contact (terminal 15 and 16), which closes when the connected equipment which should be monitored is turned on.
