24. INSTALLATION AND OPERATION INSTRUCTIONS
Mounting and installation:
Output terminal must be located on top and input terminal on the bottom. For other orientations see section 26.11.
An appropriate electrical and fire end-product enclosure should be considered in the end use application.
Cooling:
Convection cooled, no forced cooling required. Do not cover ventilation grill (e.g. cable conduits) by more than 30%!
Installation clearances:
40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently
with full power. If the adjacent device is a heat source, 15mm clearance is recommended.
Risk of electrical shock, fire, personal injury or death!
Do not use the unit without proper earth connection (Protective Earth). Use the pin on the terminal block for earth
connection and not one of the screws on the housing.
Turn power off before working on the power supply. Protect against inadvertent re-powering.
Make sure the wiring is correct by following all local and national codes.
Do not open, modify or repair the unit.
Use caution to prevent any foreign objects from entering into the housing.
Do not use in wet locations or in areas where moisture or condensation can be expected.
Service parts:
The unit does not contain any serviceable parts. The tripping of an internal fuse is caused by an internal fault. If
damage or malfunctioning should occur, immediately turn power off and send the unit back to the factory for
inspection!
