15.2 ELECTRICAL CONNECTIONS

CARE!

When connecting the equipment, please ensure that the supply

voltage is identical with the information provided on the model

type plate!

W A R N I N G !

Do not work at alive parts unless the area is known to be non-

hazardous.

NOTE!

Attention must be paid to the requirements of IEC 364 (DIN VDE

0100) when setting high-power electrical units with nominal

voltages of up to 1000V, together with the associated standards

and stipulations.

Because of the exchangeable fuse the cooler must be equipped

with a suitable external switch, which takes the cooler off the

mains.

W A R N I N G !

Cooler versions with 115V resp. 120V have a built-in transformer

to generate an internal current of 230V. That means, device internal

live parts have a current of 230V not 115V/120V.

Figure 5 shows the electrical connections at the plastic housing behind the front panel of the ECM-

ExII housing (fig. 2).

Alarm warnings for over- and under-temperature are given as a collective status alarm via a relay

output with two potential-free changeover contacts. Alarm will be released if the current temperature

is out of a range of ±3°C referring to the set-temperature (+5°C) .
