Appendix 10: UL Listing
All Repligen XCell™ ATF controller power separation boxes are ‘UL Listed’. UL Listing indicates
that Underwriter Laboratories has tested representative samples of the product and
determined that it meets UL’s requirements. These requirements are based on UL’s published
and nationally recognized Standards for Safety. In order to obtain UL Listing, Repligen’s supplier
follows UL guidelines and builds enclosures to UL508A standards for industrial control panels
intended for general industrial use, operating from a voltage of 600 volts or less. A label on the
inside of the C410 controller power box displays the UL Listing Mark. This label is purchased
through UL and serial numbered controlled. Presence of this label is proof that representative
samples of the C410v4B power box have been evaluated by UL and meet applicable safety
standards. C410 pneumatic and electronics boxes are also built by Repligen’s supplier to the
UL508A standard; however, only the power separation box is listed with UL.
