Samlexpower SEC-1223 Owner's Manual page 10

SECTION 4
Clean: The area should be free of dust and fumes. Ensure that there are no insects or
rodents. They may enter the units and block the ventilation openings or short circuit
electrical circuits inside the units.
Protection against fire hazard: The units are not ignition protected and should not be
located under any circumstance in an area that contains highly flammable liquids like
gasoline or propane as in an engine compartment with gasoline-fueled engines. Do not
keep any flammable / combustible material (i.e., paper, cloth, plastic, etc.) near the units
that may be ignited by heat, sparks or flames.
Accessibility: Do not block access to the front panel. Also, allow enough room to access
the AC inlet and the DC wiring terminals and connections at the back of the unit, as
they will need to be checked and tightened periodically.
Preventing Radio Frequency Interference (RFI): The units use high power switching cir-
cuits that generate RFI. This RFI is limited to the required standard – FCC Part 15(B), Class
B. Locate any electronic equipment susceptible to radio frequency and electromagnetic
interference as far away from the unit as possible. For additional information, please
read Section 6 titled "Limiting Electromagnetic Interference (EMI)".
4.4 MOUNTING ORIENTATION
SEC-1212 has ventilation openings on the sides and SEC-1223 has air intake openings
on the sides and exhaust openings at the bottom for the cooling fan. The units should
be mounted in such a manner so that small objects should not be able to fall easily
into the units from these openings and cause electrical / mechanical damage. Also, the
mounting orientation should be such that if the internal components overheat and melt
/ dislodge due to a catastrophic failure, the melted / hot dislodged portions should not
be able to fall out of the unit on to a combustible material and cause a fire hazard. The
size of openings has been limited as per the safety requirements to prevent the above
possibilities when the unit is mounted in the recommended orientations. In order to
meet the regulatory safety requirements, the mounting has to satisfy the following
requirements:
- Mount on a non-combustible material.
- The mounting surface should be able to support the weight of the unit
- Mount horizontally on a horizontal surface (e.g. table top or a shelf)
- Mounting horizontally on a vertical surface – The unit can be mounted on a vertical
surface (like a wall) with the DC output terminals either facing up or down
WARNING!
Mounting the unit on a vertical surface with the ventilation slots on the sides
facing up / down is NOT recommended. As explained above, this is to prevent
(i) falling of objects into the unit through the slots causing short circuit or (ii)
falling out of dislodged overheated / melted components on to a combustible
material in case of catastrophic internal failure.
