Installation of the Receiver
The permanent installation of the receiver must include fuses that protect the
equipment and wiring from overcurrent and short-circuit. In detail the power
supply of the receiver and all relay contacts must be fused.
All fuses are used as disconnecting devices. The fuses shall be easily accessible,
must submit a contact gap of at least 3.0 mm and have to be placed in the line
pole. Note that the fuse must be compatible with IEC 60127-2/V.
After the installation of the equipment, the installed cables must be bound
together (i.e. by using a cable binder) very close to the terminal blocks.
Note that there might be hazardous voltage in the receiver; therefore only certified
electricians are allowed to open the lid.
8.1 Placement of the Receiver
Select a location that is within the environmental limitations of the receiver and
where it is difficult for unauthorized persons to obtain access to the receiver. If
possible, mount the receiver with the cable glands facing downwards.
For the drilling measure of SESAM RX and RXD see chapter 17.
These receivers are preferably screwed with 4 mm screws
suitable for the surface. Think of the antenna’s size and influ
-
ence of any metal objects when choosing placement.
SESAME RX DIN is to be mounted on a DIN rail. On the
back there is a recess that the rail fits in (see 1 in fig. 7).
When the recess is pressed against the rail the snap fit
(see 2 in fig. 7) will lock the receiver to the rail automatically.
Make sure that is snap. To remove, withdraw the snap fit and
lift the receiver off the rail.
