Electrical Connections; Rs232 Serial Interface - Seneca Z Serie Manual De Instrucciones

5. PRELIMINARY INSTRUCTIONS FOR USE
The module is designed to be installed on DIN 46277 rail in vertical position.
It is forbidden to place anything that could obstructs the ventilation slits.
It is forbidden to install the module near heat sources.
Severe operating condions are as follow:
-high power supply voltage: >30 V
-Module power supply the sensor at input;
-Output used as current generator (connected to a passive module)
If the modules are installed side by side,
following cases:
-the operating temperature exceeds 45°C and at least one of the severe operating
conditions exists; or
-the operating temperature exceeds 35°C and at least two of the severe operating
conditions exist.

6. ELECTRICAL CONNECTIONS

6.1 SAFETY MEASURES BEFORE USE
Power off the module before connecting: RS232 serial interface, input,
outputs.
To satisfy the electromagnetic compliance requirements:
-use shielded cables for signal transmittion;
-connect the shield to a earth wire used specifically for instrumentation;
-insert space between these shielded cables and other cables used for power
appliances (inverters, motors, induction ovens, etc...).

6.2 RS232 SERIAL INTERFACE

The module is designed to data interchange according to the ModBUS protocol rules,
implemented by RS232 serial interface. If the module is connected to RS232 interface-port ,
its ( unchangeable
The module has a Jack stereo connector in order to connect its to RS232-bus
communication (figure 2).
6.3 CONNECTIONS
