BULKHEAD AND DECK PENETRATION
Any bulkhead penetrations which are opened must be closed and sealed using appropriate materials
thus maintaining existing water or fire proofing precautions.
OVERCURRENT PROTECTION DEVICES
All supplies to the system must be fitted with a suitably rated, clearly labelled overprotection device
such as a breaker or a fuse.
CABLE BRACKET ASSEMBLY
The SCV-A170 cable bracket assembly used
on SCV systems includes two cable clamps
that must be used to restrain the cables as
demonstrated opposite.
CABLE CLAMP BOLTS
Lightly grease the threads of the four bolts
prior to final assembly using the tube of
grease provided in the fitting kit.
CONNECTOR ACCESS
Depending on the mounting arrangement,
access to the two base plate connectors (LAN
& DC input) is restricted when the SCV/ SxV
is fully bolted to the mounting plate.
Example of a cable installed in the cable bracket assembly
In this situation, it is recommended these connections are correctly fitted and secured before the main
mounting bolts are fully tightened.
AC SUPPLIES
Where a mains powered AC to DC Power supply is to be connected to the system (not Kelvin Hughes
standard supply), the unit must be designed in accordance with the requirements of IEC 60950-
1:2005. This should include provision of a suitable rated overcurrent protective device and a
protective earth connection, made to suitable earth point on the mounting platform.
The power supply should be designed in such a way that under single fault conditions mains voltages
cannot be applied to its DC output.
MATING/ DE-MATING
The connectors are a keyed Push-Pull latching connector that can only be inserted in one orientation
into the correct mating half.
To remove the connectors pull the collar back with minimal force to release the connector, then pull
with minimal force. Correct mating and de-mating of the connector requires very little force. If effort is
required when connecting or disconnecting connectors, the wrong technique is being employed.
