7- COMMISSIONING
Before commissioning, the installation of SQML lift motor must be completed with
attention to the conditions described in the previous sections.
The specifications of the driver used must comply with the values specified on motor
plate. Check the condition of the driver before connecting the power. In case of any
failure, the driver must not be installed.
Ambient Conditions:
• Motor and driver must be installed inside an appropriate structure or enclosed lift cabin.
• The installation must comply with the protection class. The motor must be protected
against falling of foreign materials (see Chapter 5-6).
• Do not operate the motor in explosive environments.
• The temperature must be between 0-40°C.
• Humidity ratio must not exceed 95% to prevent condensation.
• Altitude must not exceed 1000 m.
7.1 Power Connection
WARNING!
The motor must not be connected to the main grid without a driver! When
connecting to the motor driver, the U, V, W and motor grounding
connections must be made with a shielded cable of proper cross-section and
the shielding must be connected to the motor and driver.
The maximum cable length is 25 m, when used with a cable of proper cross-section.

17 www.emfmotor.com
The U, V and W motor supply cables must be connected in the same sequence at both
the motor and the driver side. Incorrect connection of the phases may lead to reverse
rotation or uncontrolled movement of the motor.
The driver must switch the motor contactors while the drive does not apply current, and
it must withdraw them before the motor is energized at restart. Otherwise, switching the
motor contactors while the motor is energized, especially at zero speed, can cause failure
of the driver and contactor.
According to customer’s request, the motors are equipped with a PTO thermostatic
switch (Klixon, 130 °C maximum electrical values 250VAC/2A/cos phi = 1). The
thermal protection device of the motor must be connected to the safety circuit and it must
stop the system in case the heat is above the limit level.
WARNING!
If the motor thermal protection is not connected to the safety system,
thermal protection will not be activated in case of overheating of the motor.
This situation can cause permanent damage on the motor.

• The cable inlets must be sealed.
• The weights must be calculated according to the load values on the motor plate.
• The operating conditions must be in accordance with the information on the motor
plate.
• In driver (inverter) settings, the encoder angle must be calculated by the driver, the
motor should not be started before completing this procedure.
As well as the controls specified, the other controls required by the operating conditions
must be carried out by authorized personnel.
WARNING!
Encoder offset must be done rotational and without load on sheave.
Otherwise motor can be damaged and warranty will be voided.
7.3 Encoder Connection
CAUTION!
Remember that the phase order is directly related with the encoder angle.
Any change in phase order will change encoder angle and this can cause
uncontrolled motor operation and very high speeds.
The connection to the driver must be made according to the color codes in Encoder
Connection diagram in Chapter 6.5. The shielding of the encoder cable must be

19 www.emfmotor.com
connected also to the driver side. A grounding fault in the system may harm the encoder
and the driver.
Before operating the motor, the encoder offset angle must be determined in compliance
with the procedures explained in the manual. The motor shall not be started before the
encoder angle is identified by the driver.
Since the angle identified by the driver and the actual encoder angle will change during
the mechanical disassembly/assembly process, the angle has to be identified again after
such disassembly/assembly process.
If the length of the supplied 5 m cable will not be sufficient and an extension cable will
be required, the cable joint must not be made by hand or with a simple electric terminal;
it must be made with suitable connectors or by soldering. The extension cable to be used
must have compatible properties and cross-section with the original cable of the encoder,
and the isolation at the joints must be proper. Grounding connection must be made.
7.4 Encoder Replacement:
