5. CONNECTION AND STARTUP

5.1 CONNECTING POWER AND EARTH LINES

The units of the switcher family Diamond digital have been completely checked in

the factory and are in conformity with the safety regulation EN60950 (VDE0805)

when leaving the factory.

The respective switcher electronics (E-box) is located in a 19-inch case, suitable

for being installed in a DIN or 19-inch cabinet.

When mounting into a cabinet, care should be taken to allow for adequate horizon-

tal air circulation. The maximum ambient temperature must not exceed +40 °C dur-

ing operation.

PERMANENT EARTH CONNECTION

Due to their high leakage currents (>3.5 mA), the electronics boxes DD20 and

DD30 must be permanently connected with the earth terminal of the equipment

cabinet. For this purpose, the connector panel is provided with a separate earth

cable (green/yellow, 4 mm

with a length of 2.80 m.

Make the earth connections always before applying mains power!

For this purpose, the connector panel also carries the following warning note:

POWER CONNECTION

Prior to connecting the switcher components to the line voltage make sure that the

power supplies of control panel and electronics box are adjusted to the correspond-

ing primary voltage. The factory-adjusted voltage is indicated on the respective

connector panel (E-box, control panel) were also the type label is fastened.

Note for installing DD20 and DD30:

When operating within the line voltage range of 115V, mains-caused under-

voltages may effect an increased current consumption and as a conse-

quence an activation of the preceding fuses!

For this reason, the electronics boxes of the mixers DD20 and DD30 must be

only operated at a line voltage of 230V. When leaving the factory, the power

supply units are adjusted to the respective voltage and marked accordingly.

For switching over to another line voltage, see the corresponding section in this

manual.

In order to be able to make quickly deadly the mixer in the case of malfunc-

tion, the mains cabling of the mixer must be interruptable and at any time ac-

cessible.
