SG 524
The rear panel comprises the followings:
- 3 pins socket for main supply (CONN #1, male) [6]
- a 7/16 Socket for RF output (CONN #3, female) [5]
- 25 pins “D” type socket for I/O signals (CONN #2,
female) [7]
- RJ 45 socket on ETHERNET-MODBUS TCP interface or
9 pins “D” type socket for CANOPEN/PROFIBUS interface
(only Version 1) [8]
- BUS address switches (only Version 1) [9]
Equipment maintenance
Cleaning
Cleaning of air inlet: verify once a month. In case you need
to remove dust then proceed as follow:
- remove main line from the unit
- remove the cover
- use pressurized air from inside to outside for short time: do
not exceed or you may damage the fan and/or smd compo-
nents.
- install the cover and then power-on again.
Equipment installation
The equipment cannot operate cantilevered, it must be put on
a bench or fixed inside a cabinet by means of screws on the
front panel (which is provided with 4 holes) and supported by
means of a proper frame on the bottom for, at least, 3/4 of the
total depth.
