2. GENERAL CHARACTERISTICS
The device features a mechanical casing that is 4U in height,
and as wide as to allow up to 4 pieces to be accommodated
in a 19" rack, in addition to normal flush mounting.
The casing is made of a hot-galvanized PVC-coated plate
frame inside which the moving part that carries all the elec-
tronic circuits and the local interface slides on guides. The pull-
out action is facilitated by the presence of special "handles"
which, when the device is "plugged in", are also used to lock
the two parts. The aluminium frame of the moving part renders
the latter excellently rigid.
The device-system interface terminal blocks are located on
top of the casing and, for each electrical connection, a screw
clamp is available apt to receive up to 2 cable terminals, 4mm
2
in size. Using a special accessory that is included in the
supply, the connection can also be made through Faston
members.
Special error-fighting codes do not allow relays other than
those compatible with the housing to be inserted.
A cover lid classes the terminal block within the IP20 protection
class.
When the moving part is pulled out, the current inputs are
automatically short-circuited, whereas the voltage and auxil-
iary circuits are disconnected.
The device front bears two labels:
one plate lists the factory configuration of the device, namely
auxiliary voltage, rated current and frequency;
The other plate, always in accordance with the factory configu-
ration, provides an explanation of LED's indications.
Both labels are easily replaced with new ones, which can bear
any information as required by the client.
As far as the factory configuration relevant to output relays,
LED's, digital inputs and relevant settings are concerned,
please refer to tables A, B and C.
