Setup - Preliminary recommendations
Prior to switching on the drive
Prior to configuring the drive
Using the drive with motor having a different size
The motor could have different rating than drive. In case of smaller motor, there is no specific calculation. The motor current has to be set
on Motor thermal current
ItH parameter page 80. In case of higher size of motor, possible up to 2 sizes (example is using a 4 kW (5.5 HP)
on a 2.2 kW (3 HP) drive) it is necessary to ensure motor current and actual motor power will not pass over nominal power of drive.
Line contactor
Use with a smaller rated motor or without a motor
• In factory settings mode, Output Phase loss OPL page 80 is active ( OPL set to YES ). To check the drive in a test or maintenance
environment without having to switch to a motor with the same rating as the drive (particularly useful in the case of high power drives),
deactivate Output Phase loss
OPL ( OPL set to nO ).
• Set Motor control type

(1)These power ratings are for a switching frequency of 4 kHz, in continuous operation. The
switching frequency is adjustable from 2 to 16 kHz.
Above 4 kHz, the drive will reduce the switching frequency if an excessive temperature rise
occurs. The temperature rise is detected by a probe in the power module. Nonetheless,
derating should be applied to the nominal drive current if continuous operation above 4 kHz
is required:
• 10% derating for 8 kHz
• 20% derating for 12 kHz
• 30% derating for 16 kHz

Wiring
Recommendations
Keep the power cables separate from control circuits with low-level signals (detectors, PLCs, measuring apparatus, video, telephone).
Always cross control and power cables at 90˚ if possible.
Power and circuit protection
Follow wire size recommendations according to local codes and standards.
Before wiring power terminals, connect the ground terminal to the grounding screws located below the output terminals (see Access to the
motor terminals if you use ring terminals, page 20.
The drive must be grounded in accordance with the applicable safety standards. ER12...K/B drives have an internal EMC filter, and as such
the leakage current is over 3.5 mA.
When upstream protection by means of a "residual current device" is required by the installation standards, a type A circuit breaker should
be used for single-phase drives and type B for 3-phase drives. Choose a suitable model incorporating:
• HF current filtering
• A time delay which prevents tripping caused by the load from stray capacitance on power-up. The time delay is not possible for 30 mA
devices. In this case, choose devices with immunity against accidental tripping, for example RCDs with SI type leakage current
protection.
If the installation includes several drives, provide one "residual current device" per drive.
Control
For control and speed reference circuits, we recommend using shielded twisted cables with a pitch of between 25 and 50 mm (1 and 2 in.),
connecting the shield to ground as outlined on page 25.
Length of motor cables
For motor cable lengths longer than 50 m (164 ft) for shielded cables and longer than 100 m (328 ft) for unshielded cables, please use motor
chokes.
For accessory part numbers, please refer to the catalog.
Equipment grounding
Ground the drive according to local and national code requirements. A minimum wire size of 10 mm2(6 AWG) may be required to meet
standards limiting leakage current.
.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• The drive panel must be properly grounded before power is applied.
• Use the provided ground connecting point as shown in the figure below.
Failure to follow these instructions will result in death or serious injury.
DANGER
ER12-0.75KU, ER12-0.75K/B, ER12-0.75/3K/B - GROUND CONTINUITY HAZARD
An anodized heatsink can create an insulation barrier to the mounting surface. Ensure that you follow the recommended grounding
connections.
Failure to follow these instructions will result in death or serious injury.
• Ensure that the resistance of the ground is one ohm or less.
• When grounding several drives, you must connect each one
directly, as shown in the figure to the left.
• Do not loop the ground cables or connect them in series.

Wiring
WARNING
RISK OF DRIVE DESTRUCTION
• The drive will be damaged if input line voltage is applied to the output terminals (U/T1,V/T2,W/T3).
• Check the power connections before energizing the drive.
• If replacing another drive, verify that all wiring connections to the drive comply with wiring instructions in this manual.
Failure to follow these instructions can result in death, serious injury or equipment damage.
WARNING
INADEQUATE OVERCURRENT PROTECTION
• Overcurrent protective devices must be properly coordinated.
• The Canadian Electrical Code and the National Electrical Code require branch circuit protection. Use the fuses recommended in this
manual, page 99.
• Do not connect the drive to a power feeder whose short-circuit capacity exceeds the drive short-circuit current rating listed in this
manual, page 99.
Failure to follow these instructions can result in death, serious injury or equipment damage.
