6.9 Installing the regeneration unit (accessory)
Install the accessory regeneration unit
EPRC-400P
(sold
separately) in a location where heat dissipation capacity
equivalent to a level achieved with a heat sink [made of
aluminum, 350×350×3 mm (13.78×13.78×0.12 in.)] is
ensured.
Afx the
EPRC-400P
on a smooth metal plate offering high
heat conductivity, using two screws (M4, not supplied).
