Description of options

3.6.1

NAMUR terminal strip (option B00)

The NAMUR command source is a terminal strip that is equipped with isolation amplifiers and
relays and is located upstream of Terminal Modules TM31 and TM15.
Note
The inputs and outputs assigned to the terminals fulfill PELV (Protective extra-low voltage)
requirements.
The NAMUR terminal strip fulfills the requirements and guidelines of the standards association
for measurement and control technology in the chemical industry (NAMUR recommendation
NE37).
On the NAMUR terminal strip, certain device functions are assigned to fixed terminals. The
fixed assignment between drive signals and the NAMUR terminals represents your
standardized control logic in the device and fulfills the requirements for protective separation.
To monitor the temperature of explosion-protected motors, options for PTC tripping devices
with PTB approval and PT100 for use in hazardous areas are available.
3.6.2

Auxiliary voltage supply 3 AC 200 V 50 Hz (option C30)

The auxiliary voltage of 3AC 200 V 50 Hz provided is adapted to the required auxiliary voltage
of 3AC 400 V.
The following components require a 3 AC auxiliary voltage supply:
● Fan
● Open-loop and closed-loop control
● Protection and monitoring equipment
● DC link precharging
● Cooling unit pumps
Refer to the technical data for the auxiliary power supply current rating. The terminal
assignment is provided in the circuit diagram.
3.6.3 Suitable for marine use with individual certificate from Lloyds Register (LR) (option
E21)
The design and implementation of the drive corresponds to the requirements of the Lloyds
Register classification society.
