*Note: Class societies require an independent power supply for the EIM. The EIM must therefore not be connected to the same
power supply source as the PSM.
6.6.2 Frame ground wiring
Connect the frame ground terminal to ground/earth.
INFO
The frame ground terminal must be connected to the cabinet. The controller rack must also be connected to the cabinet, to
create a protective earth.
CAUTION
The frame ground is connected to the power supply terminals through transient voltage suppression diodes (commonly
known as transorbs). In order to protect the frame ground and power supply, no more than 36 V is allowed between the
frame ground and the power supply terminals.
6.6.3 Power supply wiring
Connect the power supply (+) to the 12 or 24 V DC power supply.
Connect the power supply (-) to the 0 V DC power supply.
