3.4 Connecting power supply
䊳
The repeater should only be supplied with a regulated
safety extra-low voltage of b19 V and +35 V
(typ24 V) as defined in IEC/EN 60950-1.
䊳
To enhance operational reliability, a redundant supply
from various sources is provided.
The operating voltages can be supplied in two ways:
– via te24 V of the terminal block
– via te24 V* of the terminal block
䊳
The common negative connection in the middle of the
terminal block is indicated by
.
䊳
The two voltages can have any (even different) values
within the specified limits.

If no signaling contact lines are connected to the
terminal block (see 3.5):
Secure the terminal block by screwing on the flange.

䊳
At the 5-pole terminal block on the upper side of the
repeater, floating contacts of a relay are provided as
a signaling contact.
If the OZD Genius G12 … is functioning correctly, the
relay picks up and the contact is opened.
If a fault or power failure occurs, the relay drops out
and the contact is closed.
䊳
The following network and repeater faults can be
signaled via the signaling contact:
Supply voltage
– No voltage supply (with redundant supply:
failure of all supply voltages)
Internal device fault
Received data
– No data received at Port 2 and/or Port 3
(e.g. cable breakage)
– No data received at any port
䊳
Limits of relay contact
– maximum switching voltage:
60 V DC; 42 V AC
– maximum switching current: 1.0 A
– maximum switching capacity: 30 W
䊳
The voltage connected to the relay must also be a
safety extra-low voltage as defined in IEC/EN
60950-1.
䊳
Always ensure that the assignment of the 5-pole
terminal block is correct. Make sure that the connec-
ting leads of the signaling contacts are adequately
insulated.
Incorrect assignment can result in destruction of the
repeaters.
䊳
Secure the terminal block by screwing on the flange.
