This document provides detailed information on how to install and operate the SG Modular
Series of Surge Protective Devices (SPD).
Series of Surge Protective Devices (SPD).
Units should be mounted as close as possible to the AC panel to be protected. It is recom-
mended that conduit, preferably metallic, be utilized to accomplish this connection.
mended that conduit, preferably metallic, be utilized to accomplish this connection.
The SG Modular Series Protectors are installed and connected in parallel ("shunt") across the
AC supply to be protected. Connecting wires do not carry the supply current, only the short
duration currents associated with the suppression of a transient event.

Identified or indicated terminals must be connected exactly with respect to the AC Power
feeding the SPD. Failure to do so may result in damage to the device or pose a danger to
personnel.

After determining a position to mount the device that
will minimize the length of the connecting wires,
drill a hole in the cabinet for the conduit to run the
wires from the distribution panel to the connecting
lugs inside the SPD. Installation is simplified if the
wires enter the enclosure at the top (see figure #2) of
the enclosure. Securely mount the TVSS unit using
1/4-20 bolts in the four (4) mounting holes provided
in the enclosure's mounting flanges.
