ATTENTION
The housing temperature may rise above the maximum ambient temperature.
Cable inlets and cables must be suitable for 70°C (158°F / 343 K) ambient
temperature or higher.
Les entrées de câbles et les câbles doivent être adaptés à une température
ambiante de 70°C (158°F / 343 K) ou plus.
See following examples:
Ethernet cable (PC and/or ModBus TCP/IP clients):
•
Standard straight cable, shielded twisted 4 wire cable or industrial CAT5
quality. For the location of the Ethernet connector see figure 5.7.
Serial Modbus:
•
Standard industrial data communication cable shielded twisted pair
•
3-wire for RS 485 communication
•
3-wire for RS 232 communication
•
2 serial ModBus ports are available, each of them independently user
configurable into RS 232 or 485
•
(Pin lay-out and link locations see figures 5.8 and 5.9)
6.4.2 Making the electrical and signal connections
ATTENTION
The following work cannot be carried out without opening the housing.
Please contact your TAC if you are not authorized to open the device
.
ATTENTION
The integrated circuits can be destroyed by electrostatic discharge.
When working on the device, it must be protected by an ESD guard
(e.g. one which complies with EN 61340-5-1). Avoid short-circuits
The cables are connected to the Interconnection board using plug connectors.
Compliance with the local/national installation guidelines (e.g. EN 60079-14) is
mandatory. The connection terminals in the interior are different for the voltage supply
and signals.
It must be ensured that enclosure IP 66 is maintained and therefore the parts used must
comply with this or a better (higher) rating. Openings which are not required must be
fitted with appropriate blind plugs.
