Introduction

The Commander C200 and C300 is a simple and flexible range of drives from 0.25 kW to 132 kW in 9 frame sizes
and two input voltage ranges (200 V, and 400 V).

This Step-by Step guide provides simple step-by-step instructions on how to mount the drive, fuse and cable
selection, wiring the drive-up, programming the drive and running the motor in analog input mode or keypad mode
on frames 5 to 9.

Check you have all the components and your drive has not been damaged during transportation.

* With frame size 7, 8 and 9, surface mounting brackets are also supplied with the drive.

STEP 2: Check model and voltage

The model number can be found on the identification label on the top of the drive. Please check that the model
and the drive voltage range is suitable for the installation.

STEP 3: Mount the drive

The drive should be mounted in an ambient temperature range of - 20 °C to 60 °C (- 4 °F to 140 °F).
Output current derating may be required at ambient temperatures >40 °C (104 °F). Refer to the relevant Power

Installation Guide (section 5.1). For UL installations, the maximum ambient temperature permitted is 50 °C (122 °F)
with any specified derating applied.

The drive can be screwed on a wall or Through-panel mounted (Refer to chapter 3 in the Power Installation Guide).
Table 3-1 highlights the clearances.

STEP 4: Select supply / motor cables and fuses

WARNING

NOTE

NOTE

The supply/motor cables and fuses or MCB’s used should follow the ratings provided in the table below:

The voltage rating of fuses must be greater than or equal to the highest supply voltage of the system.
Fuses: The AC supply to the drive must be installed with suitable protection against overload. Failure
to observe this requirement will cause risk of fire.

Ensure that grounding terminals are protected against corrosion i.e. as could be caused
by condensation.

The drive must be connected to the system ground of the AC supply. The ground wiring must
conform to local regulations and codes of practice.

The ground loop impedance must conform to the requirements of local safety regulations.
The drive must be grounded by a connection capable of carrying the prospective fault
current until the protective device (fuse, etc.) disconnects the AC supply.
The ground connections must be inspected and tested at appropriate intervals.

Additional Information

Troubleshooting

When the drive detects a fault it will display an error code. To locate and solve all error codes, a ‘Diagnostic Tool
(App)’ is available on Microsoft, Android and iOS platform via the ‘Apps’ store on Smartphone / Tablet, search for
‘Control Techniques diagnostics tool in the Apps store’. Alternatively, please download the ‘Diagnostic Tool
(App)’ from the Control Techniques ‘App Center’ or view the diagnostics section in the Control User Guide
available for download from the Control Techniques or Leroy Somer website.

Appendix A UL listing information

A.1 UL file reference

All models are UL Listed to both Canadian and US requirements. The UL file reference is: NMMS/7.E171230.
Products that incorporate the Safe Torque Off function have been investigated by UL. The UL file reference is:

FSPC.E171230.

A.2 Option modules, kits and accessories

Option Modules, Control Pods, Installation Kits and other accessories for use with these drives are UL Listed.

A.3 Enclosure ratings

Open Type

With the exception of free-standing cubicle drives, all models are Open Type as supplied. The drive housing is not
rated as a fire enclosure. A separate fire enclosure must be provided.

Type 1

When fitted with a conduit box the drives meet the requirements for UL Type 1. Type 1 enclosures are intended for
indoor use, primarily to provide a degree of protection against limited amounts of falling dirt.

Plenum rating with conduit box

When fitted with a conduit box, the drives comply with the requirements in the Standard for Fire Test for Heat and
Visible Smoke Release for Discrete Products and Their Accessories Installed in Air-Handling Spaces, UL 2043.

Through-hole mounting

The drives meet the requirements for UL Type 12 when installed inside a Type 12 enclosure with the heatsink
through-hole mounted using the sealing kit and the high-IP insert (where provided).

When through-hole mounted, the drives have been evaluated as suitable for use in surrounding air temperatures
up to 40 °C.

When the drive is through-panel mounted, the main terminal cover(s) must be removed in order to provide access
to the mounting holes. Once the drive has been mounted, the terminal cover(s) can be replaced.

The tightening torque of the securement brackets shall be advised as being 3 N m (26.6 lb.in).

Remote Keypads

Remote keypads are UL Type 12 when installed with the sealing washer and fixing kit provided.

A.4 Mounting

Drives may be surface, through-panel or tile mounted using the appropriate brackets. Drives may be mounted
singly or side by side with suitable space between them (bookcase mounting).

A.5 Environment

Drives must be installed in a Pollution Degree 2 environment or better (dry, non-conductive pollution only).
The drives have been evaluated for use at ambient temperatures up to 40 °C. The drives have additionally been
evaluated for 50 °C and 55 °C ambient air temperatures with a derated output.

A.6 Electrical Installation

OVERVOLTAGE CATEGORY

Drives have been evaluated for OVC III.

SUPPLY

The drives are suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical amperes,
600 Volts AC Maximum.

TERMINAL TORQUE

Terminals must be tightened to the rated torque as specified in the Installation Instructions.

WIRING TERMINALS

Drives must be installed using cables rated for 75 °C operation, copper wire only.
Where possible, UL Listed closed-loop connectors sized according to the field wiring shall be used for all field

power wiring connections.

Issue Number: 2

GROUND CONNECTION INSTRUCTIONS

UL Listed closed-loop connectors sized according to the field wiring shall be used for grounding connections.

BRANCH CIRCUIT PROTECTION

The fuses and circuit breakers required for branch circuit protection are specified in the Installation Instructions.

OPENING OF BRANCH CIRCUIT

Opening of the branch-circuit protective device may be an indication that a fault has been interrupted. To reduce the
risk of fire or electric shock, the equipment should be examined and replaced if damaged. If burnout of the current
element of an overload relay occurs, the complete overload relay must be replaced.

Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit protection must
be provided in accordance with the National Electrical Code (NEC), The Canadian Electrical Code, and any
additional local codes.

A.7 Motor overload protection and thermal memory retention

The devices incorporate solid state overload protection for the motor load. The protection levels are expressed as a
percentage of full-load current. Refer to the Control User Guide for further information.

In order for the motor protection to work properly, the motor rated current must be entered into Pr 06 or Pr 05.007.
The protection level may be adjusted below 150 % if required. Refer to the Control User Guide for further information.
All models are provided with thermal memory retention.

A.8 External Class 2 supply

The external power supply used to power the 24 V control circuit shall be marked: "UL Class 2". The power supply
voltage shall not exceed 24 Vdc.

A.9 Modular Drive Systems

Drives with DC+ and DC- supply connections, rated 230 V or 480 V have been investigated for use in Modular Drive
Systems as inverters when supplied by the converter sections from the Unidrive-M range. In these applications the
inverters are required to be additionally protected by supplemental fuses.

Alternatively, the inverters may be supplied by converter models: Mentor MP25A, 45A, 75A, 105A, 155A or 210A.
Contact the supplier of the drive for more information.

A.10 Requirement for Transient Surge Suppression

This requirement only applies to Frame Size 7 drives with rated input voltage = 575 V.
TRANSIENT SURGE SUPPRESSION SHALL BE INSTALLED ON THE LINE SIDE OF THIS EQUIPMENT

AND SHALL BE RATED 575 Vac (PHASE TO GROUND), 575 Vac (PHASE TO PHASE), SUITABLE FOR
OVERVOLTAGE CATEGORY III, AND SHALL PROVIDE PROTECTION FOR A RATED IMPULSE VOLTAGE
TO WITHSTAND VOLTAGE PEAK OF 6 kV AND A CLAMPING VOLTAGE OF MAXIMUM 2400 V.
