UL and CSA Agency Files
UL and CSA have issued the following reference (file) numbers for our construction approvals received for all our standard designs and over 500 custom designs.

Enclosures
The above transformers can be ordered mounted inside a NEMA enclosure with or without fuse, receptacle and line cord with plug.

Vertical Mounting
When vertical mounting of the transformer is required we recommend using our Omega or L- brackets. Learn more at our Mounting and Hardware section.
Safety Standard
UL 1411 (Non-medical) UL 544 (Medical)
CSA C 22.2 No 66, 1988 CSA C 22.2 No 1-M 90		 Agency Reference
UL file E-98086
UL file E-115282
CSA Ref. No LR 97400 C-UL file E-98086
Detailed datasheets are available for
all listed part numbers.		 Caution-If you choose to apply your own mounting solution, remember that it is important that our transformer be mounted in such a way that the mounting screw and the metal chassis will not form a closed loop through the center and thereby create a shorted turn on the transformer.
