3.1.4 Power and alarm connectors
Connect the smartLink HW-DP to a 24 V DC power supply.
Power connector
The supply voltage (18 VDC .... 32 VDC) is connected by a 3-pole terminal block. The power supply is
connected to the plug connector via flexible wires with a cross section of 0.75 to 1.5 mm². The ground
connection wire must have a cross section of 1.5 mm².
Alarm connector
The alarm output has a voltage range of 0-32V. The contact can be operated with a maximum current
of 0.5A. Connect the positive supply voltage with the COM terminal to avoid damage when the
connector accidentally mixed up.
