1 Installation Procedure
Choose the annunciator location so that the total cable
length to connect all transfer switches in the ATS
network and the remote annunciator is no more than
1220 m (4000 ft.).
Note: The maximum cable length for RS-485 networks
is 1220 m (4000 ft.).
Be sure that the mounting structure can support the
weight of the annunciator assembly. The annunciator
weights are shown below.

Prepare the annunciator enclosure, if
used.
For annunciators installed in an enclosure, drill separate
holes in the top, bottom, or left side of the enclosure for
the power and signal cables. Remove burrs and metal
chips.
Use separate conduit for power and signal
connections.
Note: The enclosures provided with the kits meet
NEMA 4 requirements.
