NOTE
Please note that if timer types "ZPS", "E81...DYD", and "PSS 2000" are used, the
synchronization voltage (which also serves as timer supply voltage) for these
timers must be generated externally and cannot be derived from pins 1 and 2 of X5
(cf. section 11.2.2).

: A change--- over contact serves as temperature contact
of the PSU, i.e. it may be used
--- as a normally--- open contact (connection between
X5/4 and X5/5)
--- or as a normally--- closed contact (connection
between X5/5 and X5/10).
5
: The synchronization voltage may vary between
21 VAC and 36 VAC, depending on the inverter type
and mains supply voltage. The maximum load is
approx. 3 mA.
