Installation
2. Installation
2.1 Inspection
After unpacking the instrument, please inspect any damage that may have occurred during the
shipment. Save all packing materials in case the instrument has to be returned one day.
If any damage is found, please file a claim with the carrier immediately. Do not return the
instrument to the factory without obtaining the prior RMA acceptance from Chroma.
2.2 Preparation for the Use
In the beginning, the instrument must be connected with an appropriate AC line input. Then,
since fans intelligent cool it, it must be installed in sufficient space for circulation of air. It
should be used in an area where the ambient temperature does not exceed 40°C.
Before connecting input/output cable, the user must remove the safety cover mounted on the
rear downside panel first. Then, the user has to refer to sections 2.3.2, 2.4, and 2.5 for
corresponding cable connection. After completion of the connection, the user should mount
the safety cover on the rear panel again.
2.3 Requirements of Input Power
2.3.1 Ratings
Input Voltage Range : 200-240V±10% V
LL
, 3 phases 4 wires ∆, or
380-400V±10% V
LL
, 3 phases 5 wires Y
Input Frequency : 47-63 Hz
Max. Current/Phase : 6460/6490: 23 A (Y type) 35 (∆ type)
6463: 15A (Y type) 20A (∆ type)
The AC source will be damaged if it is operated at an input voltage that
is outside its configured input range.
2.3.2 Input Connection
The input terminal block is located on the rear downside 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
phases 5 wires (Y), and another is 220 V
LL
3 phases 4 wires (∆). Be
careful to verify that what kind of the model you have, and make sure
that the main voltage is correct for the model.
