Electrical connection of the Equipment
Cable types
Marine approved screened cables shall always be used. This is very important for the function of
the system. See wiring diagram for maximum length and area.
Wiring
Cables shall not be installed in cable groves containing high voltage cables. Make sure the cables
are installed so they are protected against mechanical damage. In order for the enclosure cable
glands to seal properly; the outer diameter of the cables must be in within specifications, se
specification in wiring diagram.
Connecting cable screens to EMC cable glands
All cable screens shall be connected to ships ground and in one end of the cable only!
The ERRS CP2 control panel enclosure is delivered with EMC cable glands for the connection of
the screen to the ERRS CP2 enclosure. Only use the original type of cable glands! Additional cable
glands can be ordered from CM HAMMAR AB.
The Enclosure shall be connected to ships ground by the Ground connection device, see section
above.
If the screen of the 24 VDC power supply cable is connected to ground at the switchboard it shall
then be isolated from the cable gland and enclosure at the ERRS CP2 control panel.
If more than one ERRS CP2 control panel are connected together in a network the communication
cable between the control panels shall be connected in the EMC cable gland in only one of the
control panels. At the other end of the cable the screen shall be isolated from the cable gland and
enclosure.
EMC cable glands
The metal EMC cable glands are designed to ensure a good connection between the cable gland
and the cable screen. Inside EMC cable glands there are contact fingers that grips around the
cable screen and connects the screen to the cable gland and the enclosure.
