12-28V, 40A, DUAL REDUNDANCY MODULE
1. INTENDED USE
This redundancy module is designed for installation in an enclosure and is intended for the general use such as in
industrial control, office, communication, and instrumentation equipment.
This redundancy module can be used with any type of power supply as long as the maximum ratings are not exceeded.
It is suitable for power supplies with constant current overload behavior as well as any kind of “Hiccup” overload
behavior.
Do not use this redundancy module in equipment, where malfunction may cause severe personal injury or threaten
human life.
This device is designed for use in hazardous, non-hazardous, ordinary or unclassified locations.
2. INSTALLATION REQUIREMENTS
This device may only be installed and put into operation by qualified personnel.
This device does not contain serviceable parts.
If damage or malfunction should occur during installation or operation, immediately turn power off and send unit to
the factory for inspection.
Mount the unit on a DIN-rail so that the input terminals are located on the top and the output terminals on the
bottom of the unit. For other mounting orientations see de-rating requirements of chapter 17.6 in this document.
This device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do
not cover the ventilation grid (e.g. cable conduits) by more than 30%!
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 output current. Increase the side clearance to 15mm in case the adjacent device is a heat source (e.g. another
power supply). See also chapter 17.3 for further information in combination with power supplies from the PULS
DIMENSION series.
WARNING Risk of electrical shock, fire, personal injury or death.
- 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 open, modify or repair the unit.
- Use caution to prevent any foreign objects from entering the housing.
- Do not use in wet locations or in areas where moisture or condensation can be expected.
- Do not touch during power-on, and immediately after power-off. Hot surfaces may cause burns.
Notes for use in hazardous location areas:
The redundancy module is suitable for use in Class I Division 2 Groups A, B, C, D locations and for use in Group II
Category 3 (Zone 2) environments and is evaluated according to EN 60079-0:2009 and EN 60079-15:2010.
WARNING EXPLOSION HAZARDS!
Substitution of components may impair suitability for this environment. Do not disconnect the unit unless power has
been switched off or the area is known to be non-hazardous.
A suitable enclosure must be provided for the end product which has a minimum protection of IP54 and fulfils the
requirements of the EN 60079-15:2010.
