The basic
unit
and extension
unit
have the output power ratings indicated in the above table. For
loads over the rated maximum limits shown, operation should be perforhed through
an
extra
relay, capable of handling the load. Loads under the minimum limits shown
will
need
an
additional
surge absorber circuit (approx.
O.1pF
+
1OOSt)
to prevent incorrect operation due
to
leakage currents
ftowing
in
the output circuits.

Back-up fuses or circuit protectors are recommended on output circuits to prevent damage to the
circuit boards of the
PC
in
the event
of
a short circuit fault
in
an
external output circuit.
