Installation
2. Installation
2.1 Inspection
When unpacking the instrument, inspect for any damage that may have occurred in
shipping. Save all packing materials in case the unit has to be returned.
If any damage is found, please file a claim with the carrier immediately. Do not return the
instrument to the factory without prior RMA acceptance from Chroma.
2.2 Preparation for Use
To start up, the instrument must be connected with an appropriate AC line input. The
instrument is smart fan cooled and must be installed with sufficient space to the rear for
airflow. It should be used in an area where the ambient temperature does not exceed +40°C.
2.3 Input Power Requirements
2.3.1 Ratings
Input Voltage Range 6408-1 : 100 ~ 120±10% Vac, single phase
6408-2 : 200 ~ 240±10% Vac, single phase
6404 : 100 ~ 120±10% Vac, 200 ~ 240 ±10% Vac (auto range),
single phase
Input Frequency 47-63 Hz
Max. Current 6408-1 : 12 A
6408-2 : 6 A
6404 : 7 A
Max. Power 6408-1 : 1000 W
6408-2 : 1000 W
6404 : 500 W
2.3.2 Input Connection
The input power inlets are located on the rear panel of the instrument. Refer to Figure 2-1.
Input of the 6404/6408 must be connected from a three-wire single phase AC power outlet.
The power line input must have a current rating greater than or equal to the instrument fuse
current rating.
To protect operating personnel, the wire connected to the GND
terminal must be connected to an earth ground. In no event should this
instrument be operated without an adequate ground connection.
