Cabinet Mounting
T h e
following
are
recommendations and some good advice which should be
followed when SattCon 05-25/45 or SattCon
OP45
are mounted in a cabinet:
Where possible. the cabiict should be mounted in
the
immediate vicinity
of the machine that is being controlled (short cable mutes).
SattCon 05-25/45/SattCon
OP45
must be placed on a stable sheet metal
base (grounded metal plate).
Furnish the cabinets so that there is plenty of space. As a result there will
be
less
risk of electrical interference.
Consider ventilation. The temperature may become too high
on a
hot
i
summers day or at night when ventilation is reduced. Note
t h a t
the
amount of heat is greatest at the top of the cabinet.
Toothed plate connettor must be used at mounting.
so
the unit get contact
with the mounting plate.
