2 Installation

•Loosen the two chassis screws marked A halfway.

•Assemble the protective shield to the chassis and tighten the two screws to fix the shield to the chassis. Screw tightening torque: 4.8-5.3 in-lb

•Tighten the wires to one of the shield sides using tie-wrap or equivalent. Refer to the following figure.

Load wires

•Ensure that the wire length inside the shield is long enough to provide proper strain relief.

Output Voltage Sensing

	SHOCK HAZARD There is a potential shock hazard at the sense connector
WARNING
	when using a power supply with a rated output greater than 40V. Ensure that
	the local sense and remote sense wiring insulation rating is greater than or
	equal to the maximum output voltage of the power supply. Ensure that the
	connections at the load end are shielded to prevent accidental contact with
	hazardous voltages.

	Local and remote sense connections are made at the J2 connector.
	The connector has a removable plug that makes it easy for you to
	make your wire connections. Refer to the following figure for the
	terminal assignments.
	1	Remote sense (+)
	2	Local sense (+)
	3	Not connected
	4	Local sense (-)
	5	Remote sense (-)
