The “Stand Alone Paralleling Equipment” (SAPE) enables the con-
nection of generators in parallel, provided that the generator is
equipped with a paralleling device on the alternator and has the
connector with the appropriate signals.
Parallel operation is used in those cases where the load exceeds the
nominal load of one generator in operation. Using this option, gen-
erators can be connected in parallel in order to share the load pro-
portionally.
This manual describes the principle of paralleling two generators
with factory setting, using at least one SAPE unit.

The “Stand Alone Paralleling Equipment” (SAPE) consists of con-
nection cables (1), an optional frame (2) and two cubicles:
– The power control module (3)
– The contactor box (315 A, 500 A or 1000 A) (4)
The two cubicles can be mounted on the generator or on the frame.
An overview of the main parts is given in the diagram below.

A standard generator must be provided with a 15
pole connector to be able to connect with a SAPE
unit (the master generator as well as each of the
slave generators).
It is possible to convert a standard generator using a
conversion kit. This is necessary for generators built
before may 2000.
The generators do not have to be of the same type
for paralleling: any combination between QAS168,
QAS228, QAS278 or QAS338 generators is possible.
The required number of SAPE units is equal to the
number of generators to be paralleled.
It is also possible to connect a generator plus a SAPE
unit with a dedicated generator (generator provided
with integrated paralleling).
