(3) Temperature 0°C to 40°C.
(4) Transient over voltage is impulse withstand CAT II.
(5) Pollution degree 2.
2.3.2 Input Connection
The input terminal block is located on the rear panel of the instrument. The power cord must
be rated at least for 85°C. The power line input must have a current rating which is greater
than or equal to the maximum current rating of the AC source.
There are two different input voltage rating models. One is 380 V
LL
3
phases 5 wires (Y), and another is 220 V
LL
3 phases 4 wires (∆). Be
careful to verify that what kind of the main voltage you have.
See Figure 2-1 and do the following things one by one:
1. Remove the safety cover from the back of the AC source.
2. Screw the power cord to the input terminal blocks of the AC source (see Figure 2-1)
3. Slip the safety cover over the ac input terminal strip, and secure the cover with two
screws.
To protect the operators, the wire connected to the GND terminal must
be connected to the earth ground. Under no circumstances shall this
AC source be operated without an adequate ground connection.
Installation of the power cord must be done by a professional and in accordance with local
electrical codes.
