EQUIREMENTS
This device may only be installed and put into operation by qualified personnel.
This device does not contain serviceable parts.
The tripping of an internal fuse is caused by an internal defect.
If damage or malfunction should occur during installation or operation, immediately turn power off and send unit to
the factory for inspection.
Mount the device on a DIN-rail so that the input terminals are located on the bottom of the unit. For other mounting
orientations see de-rating requirements in this document. See chapter 21.12.
This device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do
not cover ventilation grid (e.g. cable conduits) by more than 15%!
Keep the following installation clearances:
40mm on top,
20mm on the bottom,
5mm on the left and right sides are recommended when the device is loaded permanently with more than 50% of the
rated power. Increase this clearance to 15mm in case the adjacent device is a heat source (e.g. another DC/DC
converter).
Caution: For use in a controlled environment according to CSA 22.2 No 107.1-01.
WARNING
Risk of electrical shock, fire, personal injury or death.
- Do not use the DC/DC converter without proper grounding (Protective Earth). Use the terminal on the input block
for earth connection and not one of the screws on the housing.
- Turn power off before working on the device. Protect against inadvertent re-powering.
- Make sure that the wiring is correct by following all local and national codes.
- Do not modify or repair the unit.
