External Power Requirements
Before connecting an external power source to the D400, ensure that the following
external power requirements are met:
•
An IEC 61010 qualified primary disconnect device and over current protection not
exceeding 15 A must be externally provided in the AC/DC mains supply system.
•
All current carrying conductors must be switched, including neutral (for AC) and
negative (for DC).
•
Primary disconnect device must be rated for the proper voltages (AC and/or DC), as
well as inrush currents for the power supplies. See section "5.1 Power Supply
Options" for peak inrush current.
•
Protective earth conductor must be connected to the provided protective earth
terminal before any mains power conductors.
•
The primary disconnect device shall be in close proximity to the D400 equipment and
within easy reach of the operator.
•
The primary disconnect device shall be marked as the disconnecting device for the
D400 equipment.
