MASTER SLAVE INTERFACE
Warning!
carefully read the chapter "Safety Instructions" in
this manual before connecting or operating the unit!
3.1
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, 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 ambient temperature is increasing. Always allow the
power supply to dry before switching it on again.
3.2
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 life of the
interface.
3.3
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.

DC POWER CONNECTIONS FOR M/S-PARALLEL
It is strongly advised to use one of the M/S PAR kits from
Delta Elektronika for best and safest results!
o
These kits include special copper bars, bolts, nuts, specific
washers, patch cables and extra safety covers.
o
Each kit is designed for a specific number of units.
o
Download the or contact factory for more information.
Place all the units in a 19 inch rack.
o
Remove the input covers from the units.
o
Remove the mains supply cables.
o
Insert the units in the rack.
o
Stack the units with minimum spacing in between them.
Distance between sets of output terminals is 3U =
133.35mm.
Assign a unit as Master.
