Prior to starting parallel operation of two generators,
following con-
nections need to be made :
1. Connect the communication cable between the generator QAS 1
and the stand alone paralleling equipment SAPE 1 (socket X33). Do
the same for QAS 2 and SAPE 2.
2. Connect the communication cable between SAPE 1 and SAPE 2 or
QAS with integrated paralleling (socket X30 or X31).
3. Route the power cables of the QAS through the bottom hole of the
contactor box of the SAPE and connect them with the contactor
(strips L1, L2, L3, N and PE on the left-hand side).

When connecting two standard generators in paral-
lel, two SAPE units must be used.
Each SAPE has two of these connections, to enable
paralleling more than two generators.
Always connect strips L1 with L1, L2 with L2 and
L3 with L3!
