General notes
WARNING!
Risk of electric shock - plastic housing
• Connect Protective Earth (PE) to the unit to avoid the risk of electric shock.
•
Setup the connection using screw-plug-terminal 61.
• The conductor providing the connection must have a wire larger than or equal to
•
2.5 mm² (14 AWG). The connection must be performed properly.
WARNING!
Risk of electric shock - sheet metal housing
• Connect Protective Earth (PE) to the unit to avoid the risk of electric shock.
•
Use the protective earth (PE) connector located at the bottom center of the sheet
metal housing.
• The conductor providing the connection must have a wire larger than or equal to
•
2.5 mm² (14 AWG). The cable length should be as short as possible.
• The connection must be performed properly.
•
WARNING!
Permissible differential voltage
The maximum permissible differential voltage between terminal 64 (B-) and terminal 61
(PE) is 100 V
RMS
. On engines where a direct connection between battery minus and PE is
not possible, it is recommended to use an isolated external power supply if the
differential voltage between battery minus and PE exceeds 100 V
RMS
.
Woodward strictly recommends to use a power supply that is fulfilling the SELV
restrictions (SELV = separated or safety extra-low voltage, see IEC)
Woodward recommends to use one of the following slow-acting protective devices in the
supply line to terminal 63:
• Fuse NEOZED D01 6A or equivalent or
•
• Miniature Circuit Breaker 6A / Type C
•
(for example: ABB type: S271C6 or equivalent)
