5.2 Electrical Installation
When installing the product, means of power disconnection shall be incorporated in the fixed wiring in order to ensure
all pole disconnection from supply mains. A fuse shall be installed in front of the inverter, with the following character-
istic: max C16.
5.2.1 Earthing / Grounding
Ground the drive properly. Refer to Figure 5 for ground connector marked with PE for its placement. Use the mounting
torque specified in section 6.1. Do not rely only on the conduit connecting to the drive case as a replacement for a
ground wire. Do not ground one inverter to another in a ”daisy-chain” manner.
WARNING: Earthing/Grounding hazard
For the operator safety it is important to ground the drive properly and follow the provided grounding guidelines.
RCD compatibility
For extra safety protection a Residual Current Device (RCD) shall be used with the inverter, provided that the local safe-
ty regulations are complied with.
Leakage current in the inverter is measured to be less than 3.5mA therefore the following RCD types can be used: A, F
or B.
Power supply system
The device is designed to be operated in a TN earthing systems. It can be used in either of the TN-C, TN-C-S and TN-S
earthing systems. For a view over the allowed power supply systems refer to Figure 4.

5.2.2 Overview of general electrical connections
A general diagram on how to connect NOVA RHC is depicted below. Detailed instructions are given below, in steps.

10 | Systemair NOVA drive 370
Analog control
The speed reference is given as 0-10V to the NOVA drive.
Modbus
As soon as a valid message is received trough Modbus, the NOVA drive will switch from analogue to Modbus commu-
nication and will continue operating in this manner until power is reset.
Enable rotary guard
To use the rotary guard, the sensor must be supplied with 10 V from Uout 10V and connected to ground, 0V. The out-
put from the sensor must be connected to RUN.
Disable rotary guard
If you do not wish to use the rotary guard feature, disable it by connecting the RUN terminal to Uout 10V. To re-enable
it you must power reset NOVA and connect according to described earlier.

5.2.3 Motor settings and direction
Figure 11 – Motor settings and direction
The dip settings (A) of the motor must be set accordingly:
• Dips 1-3 are used for motor selection. Refer to Table 5 for more information.
• Dip 4 is used for break functionality. When set to ON when the motor is stopped it will break by shorting the wind-
ings making it harder to rotate. When set to OFF it is easier to turn the rotor, when the motor is not running.
• Dip 5 must be set to OFF. The usage is reserved for fault reset.
When DIR in (B) is left unconnected the motor will rotate in one direction. If DIR is connected to 0V it will rotate in the
opposite. Connect DIR to 0V if you wish to change the direction the motor rotates. Note that the direction will change
the next time the motor starts, not when it is already rotating.
Maximum speed can be reduced and set as 50-100% of the maximum speed given by the dip switch settings. This
can be done using the potentiometer in (C).
It is possible to reset faults and warnings by toggling dip switch 5 (off->on->off) in less than 5 seconds. This will also
set the inverter to use analog control unless new Modbus messages are received.
If using the alarm signal in the relay connect it in (E).
6 Motor parameters
Motor parameters are set using dip switches 1-3. A table is depicted bellow with the correspondence between dip
switches and motor parameters selected.

7 LED behaviour
The three LEDs in NOVA RHC (red, yellow, green) behaviour is depicted below.
Start/Stop signals
Stopped and ready to start The inverter indicates it is stopped but ready to start (no faults prevent starting).
In this case the green LED flash slowly (500ms on, 500 ms off). If the inverter
has warnings or errors, then it will not show this.
Running When the inverter is running, the green LED is ON all the time. If the inverter has
warnings or errors then it will show those instead.
Retrying When the inverter has been stopped due to a fault and try to start again on its
own, it flash green fast (200 ms on, 200 ms off). It stops flashing when it has
reached the setpoint. As the control strategy is V/f, tolerance for reaching the
setpoint is 0. If the inverter has warnings or errors it will overwrite those and not
show those warnings and errors until the retry has reached the setpoint.
Faults and warnings
Warnings When the inverter has a warning it flashes the yellow LED as many times as the
warning code and then pauses (400 ms on, 400 ms off, 2000 ms pause at the
end). The action is repeated until the warnings are cleared. If more than one
warning is activated the latest warning is the one shown.
Faults When the inverter has an error that prevents it from starting then it flashes red
as many times as the error code and then pauses (400 ms on, 400 ms off, 2000
ms pause at the end). The action is repeated until the errors are cleared. If a
warning appears after an error the inverter will still show the latest error as it
has higher priority.
Rotary guard
Rotary guard passed When the rotary guard passes it shows the red-green-red-green sequence
(200ms each LED). If the inverter has no warnings or faults then this sequence
will override any LED indication immediately. If there are warnings or faults it will
wait for the fault sequence to stop toggling the LEDs indicating the error number
and will show the rotary guard sequence after.
Table 8 – LED behaviour table
8 Fault behaviour
Each error has a maximum number of retries allowed within a 30 minute window. After 30 minutes of no errors the
counts are reset. Errors are only counted when the motor is running or trying to run. Rotary Guard errors do not get
auto-reset after 30 minutes and stay forever until the reset fault command is sent. This is because at low speeds it can
take more than 30 minutes for the error to appear.
When an error occurs, the inverter will stop (except with Modbus communication error) and set the relay. If the inverter
is able to retry a start again (count < maxCount for that error) then it is considered a warning. In this case, the inverter
will inform with the warning LED sequence and will clear the relay when retrying. It will also set the warning bit in
WarningContents. The user must power reset or reset faults to clear the warnings (both LEDs and register). Modbus
communication error will never stop the inverter and will only show as a warning.
When an error has occurred enough that count >= maxCount then the inverter will stop trying to start. In this case it
will blink with the error LED sequence leave the relay set. At this point the inverter must be reset or the fault clear to
start operation again.
A summary of errors is given below.

Table 9 – Summary of errors
9 NOVA drive features
9.1 Rotary guard
Rotary guards counts the time in between pulses given by the rotary guard sensor. The time is compared against the
maximum allowed time which is calculated based on the inverter speed. The time allowed at maximum speed given by
the dip switches is 12 seconds to permit 2 full rotations (2x5 seconds) and 2 extra seconds of tolerance.
When the rotary guard passes the rotary sensor an LED sequence is played (red-green-red-green). This will play even
if the inverter output is stopped.
The rotary guard sensor is connected to the Uout (10V), 0V and RUN, to give the signal to NOVA. See Figure 10 for the
connection diagram.
Rotary guard is by default enabled and will eventually stop (coast) the Motor if the pulse is not detected for enough
time. At this point the inverter will attempt to start again up to 3 times, after which it will stop.
It is possible to disable the rotary guard feature by connecting the RUN input (Rotary guard) to Uout (10V). Refer to
Figure 9 for a diagram. When the inverter is running the motor and the rotary input is high for more than 10 seconds
the functionality is disabled. At this point a power reset is needed, to enable it again.
9.2 Purge function
When the inverter has been stopped for 30 minutes the purge function is activated. During purge the inverter will start
the motor and set it to run at 10 rpm for 12 seconds. After this time the inverter is stopped again. The sequence is
repeated after 30 minutes of inactivity.
9.3 Brake functionality
If dip switch 4 is set to ON the brake functionality is activated. When the motor is stopped and if the brake functionality
is activated it will brake the rotor by shorting the windings. With brake activated it is harder to move the rotor, when
stopped. If brake functionality is activated it can take up to 10 seconds to start braking once the motor is stopped.
9.4 Direction input
It is possible to use the direction input to change the direction the motor is spinning. If nothing is connected, the direc-
tion input is pulled high. To reverse the direction connect the direction input to 0V. Refer to (B) in Figure 11 for a con-
nection diagram.
Note that direction will not change once the motor is running.
9.5 Automatic test
Activate dip switch 5 for more than 10 seconds to start the automatic test. During automatic test the motor will go to
maximum speed and wait there for 10 seconds. After this it will ramp down and stop for another 10 seconds. The pro-
cess is repeated again and again, until stopped by setting the dip switch 5 off.
