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.

»To connect the power source to the D400:

1.Remove the terminal block TB1 protective plastic cover.

2.Connect power source as follows:

If your power supply is…	then…
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 -VDCconnection 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]
