modules.
With reference to Table Figure 11-11 and

screws on the terminal block. These must be
removed if a you wish to make a manual
connection, for example via a clean relay
contact.

REMOTE n clamps, otherwise the circuits of
the modules will be irremediably damaged.
These must be exclusively open or
connected to X9 or other clean contact.
NOTICE
It is important to leave a gap of 30 cm of
cable pocketed in the ACBOX to allow the
full extraction of the AC drawer
