ISOLATED ANALOG INTERFACE
Warning!
carefully read the chapter "Safety Instructions" in
this manual before connecting or operating the unit!
7.1
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, to prevent break-
down. Condensation can occur during a period the power
supply has been switched off (or operating at no load) and
the ambient temperature is increasing. Always allow the
power supply to dry before switching it on again.
7.2
TEMPERATURE & COOLING
The storage temperature range is
–40 to +85 °C.
The operating temperature range is
–20 to +50 °C. But this
temperature range only holds when the air-intake and air-
outlet of the power supply are unobstructed and the
temperature of the air-intake 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 lifetime of the
interface.
7.3
FIRMWARE
First install the interface inside the unit, then check the
firmware package is P0120 or higher. In the front menu, go
to: SYSTEM INFO -> UNIT-> VERSION.
If an update is required, refer to the SM15K unit manual
how to do this.

HARDWARE INSTALLATION
Warning!
Never make connections to the Power Inputs
and Outputs or the Sense Connector when the SM15K unit
is connected to the mains supply or power outlet!
Safety covers are used to cover these in- and outputs.
7.4.1
INSERT INTERFACE IN THE UNIT
Switch off the unit.
Disconnect the unit from the mains supply.
Wait for 3 minutes to allow internal circuits to discharge.
Select a none used slot at the rear side.
See figure 7 - 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.
7.4.2
CONNECT INTERFACE
The connector on the analog interface is a female 15pole
D-connector.
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.
To avoid hum or noise, the programming cable may have to
be twisted in some cases.
With regards Safety, the analog programming connector is
at the level of Protective Earth.
Connect the cable to the programming source.
The pinning of the INT MOD ANA is similar to other Delta
Elektronika power supplies, see fig 7 - 2.
Connect the mains supply again and check all the safety
covers are installed.
Switch on the unit.
