Connection
General Information
The following chapters describe the connection of all data and power-supply lines necessary for safe opera-
tion. During electrical installation, observe the regulations for the setup of high-voltage systems.

NOTE
If using stranded wires, bootlace ferrules must be used.
Auxiliary-Voltage Connection
The auxiliary voltage is connected by way of the N/- L/+ terminals on the device. The assignment of the
terminals is printed on the front of the device (see chapter
Figure 2-1 ). As the device does not have its own
switch, the switch must be installed externally.
Terminals:
Power supply:
Max. 2.5 mm
2
(AWG 14 to AWG 24)
Stripped length 3 mm to 5 mm
Conductor cross-
section: 0.14 mm 2 to 1.5 mm 2 (AWG 16 to AWG 22)
Fault-Signaling Connection (Life Contact)
The fault-signaling connection (Life Contact) is equipped with an isolated contact that is automatically closed
by the device in case of an error.
A power-supply outage is considered to be an error. The fault-signaling contact is connected to the device via
the Life Contact terminals. The assignment of the terminals is printed on the front of the device (see chapter
Terminals, Page 15 ).
