WARNING

ELECTRIC SHOCK

Connect only a supply voltage that corresponds to the type plate of your
device.
Never insert sharp objects (small screwdrivers, wires, etc.) into the
connection terminals for electric conductors, and do not touch the terminals.
Observe the maximum values for the contact load of the signal contact.

Failure to follow these instructions can result in death, serious injury,
or equipment damage.

The supply voltage and the signal contact are connected via a 6-pin terminal
block with a snap lock.

2.6.1 Supply voltage

The supply voltage can be connected redundantly. Both inputs are
uncoupled. There is no distributed load. With redundant supply, the power
supply unit with the higher output voltage supplies the device on its own. The
supply voltage is electrically isolated from the housing.

You can choose between DC or AC voltage when connecting the supply
voltage. You use the +24V and 0V pins to connect the AC voltage (see

figure 12).

Figure 12: Connecting the supply voltage at the 6-pin terminal block

With a non-redundant supply of the supply voltage, the device reports the
loss of a supply voltage. You can prevent this message by changing the
configuration in the Management.

2.6.2 “FAULT” signal contact

 The signal contact (“FAULT”, for pin assignment of terminal block, see

figure 12) monitors the functioning of the device, thus enabling remote

diagnostics.

The potential-free signal contact (relay contact, closed circuit) reports
through a break in contact:

 The detected inoperability of at least one of the two voltage supplies

(voltage supply 1 or 2 is below the threshold value).

 The device is not operational.
 The defective link status of at least one port with active link monitoring. In

delivery state, link monitoring is inactive.

 Failure of the ring redundancy reserve.
 Errors detected during the self-diagnostic test.

 Pull the terminal block off the device and connect the power supply and

signal lines.

2.7 Mounting the terminal block

 Mount the terminal block for the voltage supply and signal contact on the

front of the device using the snap lock. Verify that the snap lock latches in
place.

2.8 Operating the device

 By connecting the supply voltage via the terminal block, you start the

operation of the device.

2.9 Connecting data cables

In general, adhere to the following recommendations for data cable
connections in environments with high electrical interference levels:

 Keep the length of the data cables as short as possible.
 Use optical data cables for the data transmission between the buildings.

32

Installation RS20/RS30-...U

Release 03 08/2019

 When using copper cables, provide a sufficient separation between the

power supply cables and the data cables. Ideally, install the cables in

separate cable channels.

 Used shielded cables (SF/UTP cables as per ISO/IEC 11801:2002).

 Connect the data cables according to your requirements.

3 Monitoring the ambient air temperature

Operate the device below the specified maximum ambient air temperature
exclusively.

See “General technical data” on page 38.

The ambient air temperature is the temperature of the air at a distance of 2 in
(5 cm) from the device. It depends on the installation conditions of the device,
e.g. the distance from other devices or other objects, and the output of
neighboring devices.

4 Maintenance and service

 When designing this device, Hirschmann largely avoided using high-wear

parts. The parts subject to wear and tear are dimensioned to last longer

than the lifetime of the product when it is operated normally. Operate this

device according to the specifications.

 Relays are subject to natural wear. This wear depends on the frequency

of the switching operations. Check the resistance of the closed relay

contacts and the switching function depending on the frequency of the

switching operations.

 Depending on the degree of pollution in the operating environment, check

at regular intervals that the ventilation slots in the device are not

obstructed.

Note: You will find information about the complaints and returns procedures
on the Internet under
