4.6.2 Fitting FS32 spur surge-protection modules
FS32 modules are pluggable surge-protection units that integrate easily with the standard
pluggable connector and which direct excessive spur surge currents to the protective
local ground.
Figure 4.7 - FS32 spur surge-protection module fitted on spur connector
To fit an FS32:
1. Unscrew the two captive screws securing the standard pluggable connector (supplied
on the carrier) and remove it from its socket.
2. Insert the FS32 module into the now vacant socket on the carrier, tighten the two side
securing screws, and the central “protective ground” screw, to a recommended torque
of 0.4 Nm.
3. Fit the connector (removed at Step 1 above) into the socket on the FS32 and tighten
its two securing screws also to a recommended torque of 0.4 Nm.
Removal of a Spur Surge module is the reverse of the fitting process. See also Section
5.3.1 on page 15 for information on cable ‘adjustment’ if one of these modules is
taken out of use.
4.7 Final checks
Check:
• that there are no loose cable ends that could cause an open or short circuit.
• that the protective trunk wiring cover is in place on the Trunk Terminal Assembly.
• that no tools (e.g. screwdrivers) or loose items are present.
• that if, and only if, the assembly is the last one on the fieldbus segment, that a
9378-FT Terminator module is fitted into the socket on the TTA.
• that the required grounding link is securely connected.
