Connecting Power Supply; Connecting Signaling Contact Lines - Belden Hirschmann OZD Genius G12 Serie Manuel

3 Setting Up

3.4 Connecting power supply

The repeater should only be supplied with a regulated
safety extra-low voltage of between +19 V and +35 V
(typically +24 V) as defined in IEC/EN 60950-1.
To enhance operational reliability, a redundant supply
from various sources is provided.
The operating voltages can be supplied in two ways:
– via terminal +24 V of the terminal block
– via terminal +24 V* of the terminal block
The common negative connection in the middle of the
terminal block is indicated by
The two voltages can have any (even different) values
within the specified limits.

3.5 Connecting signaling contact lines

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.
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
Limits of relay contact
– maximum switching voltage:
– maximum switching current:
– maximum switching capacity: 30 W

The voltage connected to the relay must also be a
safety extra-low voltage as defined in IEC/EN
60950-1.
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.
Secure the terminal block by screwing on the flange.
