General Safety Instructions
These products are designed to be PCB mounted and for use
within other equipment or enclosures. For safe installation and
operation, carefully follow the instructions below:
Fusing
An external ceramic sand-filled fuse is needed for protection.
Installation Method
The unit can be mounted in any direction. Position single or
multiple units with proper spacing to allow for adequate air
ventilation. The case temperature of each unit should not exceed
the temperature range as noted in the data sheet.
Avoid placing PCB traces for the DC input and DC output directly
under the unit to limit the possibility of unwanted conducted noise.

Installation Data Sheet
Soldering and Cleaning
Note: The pins of this module are coated with Tin. To assure the
solder-ability, modules should be kept in their original shipping
containers to provide adequate protection. Also, the storage
environment should be controlled to prevent oxidation of the pins.
Following wave solder, the converters should be given an
opportunity to cool to within 10°C of the cleaning solution
temperature. Cleaning while at a higher temperature may
increase the risk of vacuum absorption of the solution into the
converter between the pins and potting material during cooling.
It is recommended that during the wash process, the date code
screening is protected to avoid erasure.
Flow soldering : 260±10°C less than 15 seconds
Soldering iron : 370±10°C less than 5 seconds
