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. 

1. 

Remove the terminal block TB1 protective plastic cover. 

2. 

Connect power source as follows: 

AC 

Connect the AC line connection to the L connection 

point(s) and the AC neutral connection to the N 

connection point(s) on terminal block TB1 

DC 

Connect the DC power supply, observing the correct 

polarity, to the +VDC and -VDC connection point(s) on 

terminal block TB1 

 

For proper connection, the recommended tool torque settings for power terminal 
screws are 10.8 in-lb [1.22 Nm] 
See also wiring diagrams below for different power configurations.
