4.5 Mounting the CDB650-204 connection module
b
Mount the CDB650-204 connection module in the vicinity of the device.
When using the serial data interfaces (RS-232), the recommended cable
length between the devices is 5 mmaximum. Mount the CDB650-204 in
such a way that the connection module can be accessed at all times, see
the CDB650-204 connection module operating instructions.

Electrical installation
Notes on electrical installation
•
The electrical installation must only be performed by an electrically qualified person.
•
Standard safety requirements must be met when working on electrical systems.
•
Electrical connections between the read/write device and other devices are
only allowed to be made or separated in a voltage-free state. Otherwise,
there is a risk of damaging the devices.
•
When using connecting or extension cables with an open end, make sure
that bare wire ends are not touching (risk of short-circuit when the supply
voltage is switched on). Wires must be appropriately insulated from each
other. This also applies to unused wires.
•
Wire cross-sections in the supply cable from the customer’s power system
must be designed in accordance with the applicable national standards.
•
All circuits connected to the device must be designed as SELV circuits.
Supply voltage
•
Supply voltage DC 18 V to 30 V:
°
When the device is connected to the optional SICK CDB650-204 or
CDM420-0006 connection module using a SICK cable.
°
When the device is operated without a connection module using a SICK
cable. 2 A fuse protection at the start of the feeding supply circuit.
•
Optional 12 V to 30 V DC supply voltage when the device is operated without
a connection module using SICK supply cable part no. 6048319
(2 x 0.25 mm
2
, 10 m). 2.5 A fuse protection.
•
The voltage supply or power supply unit must satisfy SELV requirements in
accordance with the currently applicable EN 60950-1. (SELV = Safety Extra
Low Voltage).
NOTE
The voltage supply via a power supply unit must be capable of buffering a
brief power failure of 20 ms.
Required input voltage on connection module
The following components cause voltage drops in the supply current circuit:
•
Depending on length, the connection cable from the connection module
(CDB650-204 or CDM420-0006) to the device
•
The connection module, to a slight extent
In order to compensate for this loss when operating the device at the lower end of
the supply range (18 V DC), the following, higher input voltage must be applied to
the connection module:

WARNING
Risk of injury and damage caused by electrical current!
As a result of equipotential bonding currents between the device and other
grounded devices in the system, faulty grounding of the device can give rise
to the following dangers and faults:
•
Dangerous voltages are applied to the metal housings.
•
Devices will behave incorrectly or be destroyed.
•
Cable shielding will be damaged by overheating and cause cable fires.
Remedial measures
•
Only skilled electricians should be permitted to carry out work on the
electrical system.
•
If the cable insulation is damaged, disconnect the voltage supply imme‐
diately and have the damage repaired.
•
Ensure that the ground potential is the same at all grounding points.
•
Where local conditions do not meet the requirements for a safe earthing
method, take appropriate measures (e.g., ensuring low-impedance and
current-carrying equipotential bonding).
NOTE
For recommended measures for eliminating hazards, see the “Electrical
installation” chapter in the RFU63x/65x RFID read/write device (UHF) operat‐
ing instructions in the Internet at:
.
NOTICE
Risk of damage to the device due to reverse polarity of the supply voltage!
The supply voltage input for the device is designed with internal circuit protec‐
tion to provide reverse polarity protection. The internal functional earth, which
also corresponds to the negative pole of the supply voltage for the device, is
connected directly to the metal housing of the device due to reasons relating
to high frequency.
If the supply voltage is polarity-reversed, this will not cause any damage pro‐
vided that the following conditions are met for the device:
The device is not connected in an electrically conductive manner, either via
other cables or via its housing, to other peripheral devices which use the
same reference potential.
NOTE
For a more in-depth examination, see the “Electrical installation” chapter in
the RFU63x/65x RFID read/write device (UHF) operating instructions on the
product page on the Internet at
.
Connecting the device electrically
NOTE
The USB interface of the device is used in industrial environments only as a
service interface for temporary use (e.g. for configuration, troubleshooting).
Permanent use in operational use of the system as a host interface is not
intended.
NOTE
The numbering of the data interfaces (Aux 1, etc.) in the following block dia‐
grams provides a better overview, but is not shown in configuration tools
such as the SOPAS ET configuration software.
1.
Connect the communication interface (e.g. Ethernet) of the device directly to
the computer (PC) using the suitable cable.

with optional connection module:
2.
If external antennas such as RFA630-000 (region Europe and possibly other
countries) are used, connect the antennas to the device using suitable con‐
necting cables. A maximum of 3 external antennas can be connected.
3.
Connect "Power/Serial Data/CAN/I/0" connection to the female connector
on the CDB650-204 using a suitable cable.
4.
If necessary, connect a read cycle trigger sensor, such as a photoelectric
retro-reflective sensor, to the “Sens/IN 1” switching input of the
CDB650-204.
5.
Depending on the length of the connecting cable, supply the device with
DC voltage between 18 V and 30 V.
✓
After successful initialization, the “Device Ready” LED lights up green.
6.
Turn on the computer (PC) and start Windows.
