5 Power supply
All models except IPL-X-100 :
These products provide a dual power inputs allowing a redundancy power supply.
The supply voltage must be regulated and strictly between 10 and 60 Volt DC (nominal: 12
– 48 VDC).
At power up the inrush current can reach 20 A for 100 µs.
IPL-X-100 :
These products provide a single power input.
The supply voltage must be regulated and strictly between 10 and 30 Volt DC (nominal: 12
– 24 VDC).
At power up the inrush current can reach 20 A for 100 µs.
6 Earthing
IPL-A, IPL-DAC et IPL-DAE :
For safety and EMC reasons, the ground terminal must be connected to the protective earth of the installation.
Other IPL :
For EMC reasons, the ground terminal must be connected to the functional (or protective) earth of the
installation.
7 RS232 serial connexion (IPL-X-220, IPL-X-230)
Cables can be provided to connect the product to DTE and DCE as follows:
RS232 cables
Reference Connector Function
CAB592 SubD 9 male To connect a DCE to the product
CAB593 SubD 9 female To connect a DTE to the product
CAB609 Wires To connect a device providing a specific connector
The RS232 cable must be shorter than 10 meters.
8 RS485 serial connexion (IPL-X-220)
The RS485 interface is not isolated.
Two 10 KOhm bus polarization resistors are included inside the product.
If the RS485 line is longer than10 meters or if the data rate is greater than
19200 b/s, it is necessary to connect one 120 Ohm matching resistor at
each end of the line and two 390 Ohm polarization resistors at one of the
two extremities of the line.
