Safety Switch
Close to the controller installation, there should be a safety switch enabling total power supply
disconnection of the equipment. This means a common switch for all supply voltages,
for example networks A, B and C discussed above.
The main use of the safety switch is to disconnect the power supply in a clear and safe way
during work in the cabinet.
Install the safety switch in a visible place (outside any cabinetry) within 3 m of the controller
installation.
a.c. Supply
Essential information includes:
•
For the supply A (and redundant B) class II or class III a.c. networks can be used
alternatively as a standard solution.
•
For the supply C there are different options. Select a suitable power distribution unit with
respect to available class II and class III networks and your requirement on redundancy.
See
.
•
Single and return (class II), as well as two-phase (class III) connection, of a standard
controller are possible.
d.c. Supply
Essential information includes:
•
When using a d.c. supply, only battery-supplied systems with a non-grounded battery can
be used for direct supply of Advant OCS. With this type of supply, the battery is grounded
in the Advant OCS equipment.
•
Supply from a grounded battery requires an isolating d.c./d.c. convertor.
•
Supply C is always an a.c. supply, see heading above.
Protective Earth
Always provide Advant OCS cabinets supplied with 230 V a.c. with a protective earth.
Current Consumption and Fusing
Instructions for current consumption calculations are provided in
This section also gives dimensional rules for distribution board fusing.
For a quick guide to the power consumption to use whenever you need estimated figures is also
located in this section.
Uninterrupted Power Supply
In certain applications, you must guard against brief voltage failures by using an uninterruptable
supply. See
for important considerations in doing so.
