2. Installation
2.1 Inspection
First, inspect any damage that may have occurred during the shipment after unpacking the
instrument. Save all packing materials in case the instrument has to be returned.
If any damage is found, please file a claim against the carrier immediately. Do not return the
instrument to the factory without obtaining the prior RMA acceptance from Delta.
2.2 Preparation for the Use
Before start using, the instrument must be connected with an appropriate AC line input.
As the instrument is cooled by fans, it must be installed in an area with sufficient space for
air circulation. It should be used in an area where the environment temperature does not
exceed 40
℃
.
2.3 Requirements of Input Power
2.3.1 Ratings
Input Voltage Range: 190-250 VLL, 3 phases 4 wires
△
(ABT A), or
329-433 VLL, 3 phases 5 wires Y
(ABT B)
Input Frequency: 47-63Hz
Max. Current/Phase: 35 A / phase (ABT A) or 25A/phase (ABT B)

WARNING
*** CAUTION ***
The AC source may be damaged if it is operated at an input voltage that is over
its configured input range.
2.3.2 Input Connection
The input terminal block is located on the instrument rear panel. The temperature rating of
the power cord must be rated at least for 85
℃
. The input power line must have a current
rating, which is greater than or equal to the maximum current rating of the AC source.
Recommend to put a 40A breaker (ABT A) (30A breaker (ABT B)) at AC input side.

WARNING
*** CAUTION ***
There are two input voltage rating models, one is 380 VLL 3 phases 5 wires (Y
connection) used for (ABT B model), and the other is 220 VLL 3 phases 4 wires
(
Δ
connection) used for (ABT A model). Be careful to verify the model you have,
and make sure that the main voltage is suitable for the model! AC source may
not operate properly if one phase input voltage is missing, please recheck the
connection.
