4.4.1 Power Supply (Terminals 1, 2 & 3)
The OTS-EL requires a regulated 24VDC or 24VAC power supply.
Figure 4.7: Electrical Connections
– OTS-EL Power Supply
4.4.2 Line Connections (Terminals Ua, Ub & Uc)
The OTS-EL contains an internal high voltage barrier that allows the OTS-EL to directly interface with
the phase conductors.
The high voltage connections from the OTS-EL
must be made on the load side of the outlet’s contactor
/ breaking device.
