4.1 General instructions
If the electronics module is defective, it can be replaced by the user.
In Ex applications, only instruments and electronics modules with ap-
propriate Ex approval may be used.
If there is no electronics module available on site, one can be ordered
from the VEGA agency serving you.
First of all check if you are using the suitable electronics module.
Compare the new electronics module with the existing one. The
