Electrical Installation; Sub-Sea Components - Teledyne 440 System Manual

4 Electrical Installation

This section of the Manual explains how to connect the SDC and the sub-sea components of the
standard 440 System. You should attempt the electrical installation only after you have followed the
instructions in Chapter 3 "Physical Installation"
Also included in this section are detailed instructions that tell you how to change the communication
method used between the SDC and the SEP.
The standard 440 System uses RS232 communications. To select an alternative
communication method you must change the settings of links inside the SEP and
the switch on the rear of the SDC comms module. If the SDC being used is not an
SDC9 or SDC10, the current loop converter card will not have an external switch.
It will need to be modified by changing the internal links on the Current Loop Con-
verter board. If you need to change the communication method you must make
the necessary link adjustments inside the SEP before you mount it onto the ROV.
The SDC provided with the 440 System is provided with Windows 7. DeepView for
Windows can be installed on an additional machine, but Teledyne TSS stress that
the operating system must have a minimum specification of Windows XP. The
specification of the SDC provided can be found in Section 8 "System Specifica-
tions" beginning on page 8-1. This should be used as a guideline if you are plan-
ning to use DeepView for Windows on an alternative PC.

4.1 Sub-sea Components

There is a risk of death or serious injury by electric shock when you work on the
electrical distribution system. Only a competent engineer who has the relevant
training and experience should make the connection to the ROV electrical
distribution system.
Power-off the ROV and isolate the mains supply voltages before you connect the
440 System to the electrical distribution system. Observe all relevant local and
national safety regulations while you work on the ROV and on the 440 System.
Do not reconnect the mains electrical supply to the ROV or to the 440 System until
you have completed all work and you have fitted all safety covers and ground
connections.
This sub-section explains how to complete the electrical installation of the sub-sea components.
