5.1.2 Installing the top-hat rail
The IE-GPRS-I/O can be fastened on a top-hat rail which complies with
the standard EN 50022:
35
1
7,5
This top-hat rail must be fastened on the control cubicle wall such that a
conductive connection is provided.
Observe the instructions of the manufacturer with reference to
fastening.
Installation
Pull the top-hat rail downwards, at the same time pushing the device
back onto the top-hat rail.
Removal
The top-hat rail adapter is offered in two variants, resulting in the
different direction of movement when unhooking from the top-hat
rail. Therefore, before unhooking, check whether the IE-GPRS-I/O
is to be moved upwards or downwards against the retaining
spring.
To remove the device, unhook it by pushing it firmly upwards or
downwards, and then remove it forwards from the top-hat rail.
