Option 602 Installation Guide
WARNING ENERGY HAZARD. The Series 668xA power supplies can provide more than 240 VA at more than
2 V. If the output connections touch, severe arcing may occur resulting in burns, ignition or
welding of parts. Do not attempt to make connections while the output is live.
Introduction
The Option 602 kit provides bus bar spacers to permit parallel operation between vertical power supplies, such as those in
an equipment rack.
Installation
Each kit has two bus bar spacers and the required hardware for attaching the spacers to the - and + bus bars. The spacers
have tapped holes for receiving the screws that are inserted through clearence holes in the bus bars. Either spacer may be
used with either bus bar. Secure the spacers on opposite sides of the bus bars as shown in the figure. Be sure to insert the
flatwashers and lockwashers.
When the spacers have been installed, connect the bus rails between the two power supplies. Use the original bus bar
hardware or the hardware provided with the Bus Bar Hardware Kit 5080-2313 (see option 601)

Option 601 Installation Guide
WARNING ENERGY HAZARD. The Series 668xA power supplies can provide more than 240 VA at more than
2 V. If the output connections touch, severe arcing may occur resulting in burns, ignition or
welding of parts. Do not attempt to make connections while the output is live.
Introduction
The Option 602 kit allows bench operation of the Series 668xA power supplies. It provides an insulating cover and means
for vertical conections to the output bus bars to prevent accidental contact between the two bus bars and external objects at
the rear of the power supply.
Installation
Each option contains an output cover with a cutout to permit the load leads to be run down from above or up from below the
power supply. The option also includes four screws for fastening the cover to the rear panel, a bus bar spacer with mounting
hardware, and a bus bar hardware kit for connectiong the load leads to the output bus bars.
Install the bus bar spacers on either output bus bar to permit clearence between the - and + output leads (see Option 602
instructions for mounting details). Using the bus bar hardware kit, connect the output leads either from above or below the
bus bars. Then install the output cover and secure it with the four machine screws provided.)
