CONDENSATION
•
During normal operation, humidity will not harm the interfaces,
provided the air is not aggressive. The heat normally produced in
the power supply will keep it dry.
•
Avoid condensation inside the interfaces, break-down could be
the result. Condensation can occur during a period the power
supply has been switched off (or operating at no load) and the am-
bient temperature is increasing. Always allow the power supply to
dry before switching it on again.

TEMPERATURE & COOLING
•
The storage temperature range is –40 to +85 °C.
•
The operating temperature range is –20 to +50 °C.But this tem-
perature range only holds when the air-intake and air-outlet of the
power supply are unobstructed and the temperature of the air-in-
take is not higher than +50 °C.
•
When the power supply is mounted in a cabinet, please note that
the temperature of the air-intake should be kept low and avoid a
short circuit in the airflow i.e. the hot air leaving the air-outlet
entering the air-intake again.
•
Please note: a lower temperature extends the life of the interface.

FIRMWARE
•
Before hardware installation of the interface, check the firmware
package is P0114 or higher. In the front menu, go to:
SYSTEM INFO -> UNIT-> VERSION.
•
If an update is required, refer to the SM3300 unit manual how to
do this.

HARDWARE INSTALLATION
Warning!
Never make connections to the Power Input, the Power
Output or the Sense Connector when the SM3300 unit is connected
to the mains supply!
Safety covers are used to cover these in- and outputs.
INSERT INTERFACE IN THE UNIT
•
Switch off the unit.
•
Disconnect the unit from the mains supply.
•
Wait for 3 minutes to allow internal capacitors to discharge.
•
Select a none used slot at the rear side.
The Interface can be inserted in any free slot 1...4.
See figure 6 - 1.
•
Unscrew the 2 torx T10 screws and remove the slot cover.
•
Insert the interface and place the 2 screws back to secure the
interface.
CONNECT INTERFACE
•
The available connectors on the digital user I/O interface are high
density 15pole D-connectors, female, see fig. 5 -2.
•
Use cables with an internal wiring with a diameter of 0.3 ...
0.5mm
2
and with a sufficient voltage rating for the voltage of the
circuit.
•
With regards Safety, the user I/O connectors are at the level of
Protective Earth.
•
Connect the cable to the programming source.
•
Connect the mains supply again and check all the safety covers
are installed.
•
Switch on the unit.
•
The LED indicated in fig. 6-2 will light up.
Warning!
carefully read the chapter "Safety Instructions"
in this manual before connecting or operating the unit!
