Mounting Instructions
There must be a clearance of at least 5-7/8 inches (150 mm) in all
directions. A good bonding between the SED2 and the metal
backplate is necessary to ensure good grounding and low RFI (radio
frequency interference). If necessary, remove some backplate paint
and/or use toothed washers to ensure safety and EMC (electro-
magnetic compatibility). Earth braid screened armored cable provides
the best bond.

obstruct the vents on the SED2. Additional ventilation may
be required if the SED2 is mounted horizontally.
