Earth
SF910i must be connected to earth by means of a suitable cable connected to the
ground protection terminal available on the enclosure body (it is identified by a yellow
earth symbol).
The maximum allowed length of the earth cable is three meters. See
for
specifications of the earth cable.
Wiring: Terminal Equipped Version
Refer to
and
to properly select the external cable.
The multi-conductors cable must be prepared as shown in
.
Once the SF910i is physically installed in its final location, remove the rear cover.
The cable, once inserted in the cable gland, must be inserted in the cable entry hole of
the SF910i enclosure.
Then, the cable gland can be screwed into place. Do not tight it on the cable.
Pull half a meter (approximately) of cable from the rear of the SF910i. This is facilitated
by the presence of the cable guide that avoid hitting against the internal circuit board
and facilitates the passage of the cable.
Next, connect each conductor to the corresponding terminal block and tight its screw.
Terminate the cable shield, and connect it to the terminal named “SHIELD”. Now, connect
each cable pin into corresponding terminal and screw it firmly, press the conductors
gently to keep it separated from the threading of the cover and bottom of Touchkey/LCD
assembly.
Double check of all connections, especially the connection to the relay contacts
(J3/J4 terminal block) and verify that all cables are correctly inserted in the screw
terminals, that all the screws are tight and that no conductors are exposed.
This is of extreme importance for two reasons:
–
First, if the wires of the relay contacts become short-circuited, then the user will
lose the flame-off detection, and this is a severe un-safe condition.
–
Second, when the relay contacts are connected to 50V
AC
or other dangerous
voltages, there is an obvious risk of electric shocks or short circuits between
conductor and the enclosure.
Then, the user is ready to tight the cable gland and to complete the external wiring.
To correctly identify each terminal, refer to the below figure and table.
