Thank you for using RHYMEBUS RM6 series (9426) drive. For proper operations
and safety purposes, please do read and follow specific instructions contained in this
manual before using the product. The manual shall be placed on the top of the
machine, and all the setup parameters and reference numbers must be properly
recorded inAttachment 3 to facilitate future maintenance and repairs.
PREFACE

Please read this manual thoroughly and pay attention to the safety precautions
marked with “ DANGER ” or “ CAUTION ” before the installation, wiring,
maintenance, or troubleshooting.
Only the qualified personnel may proceed with the installation, wiring, testing,
troubleshooting, or other tasks.
※Qualified Personnel: Must be familiar with the fundamentals, structures,
characteristics, operating procedures, and installation, and this personnel must
read the manual in details and follow the steps of security measures to prevent
possible dangers.
DANGER
User may cause the casualty or serious damages if user
does not abide by the instructions of the manual to execute
the tasks.
CAUTION
User may cause injuries to the people or damage the
equipment if user does not abide by the instructions of the
manual to execute the tasks.
※Although the “ ” mark may indicate minor damages, serious damages or
injuries may be possibly incurred if the caution is not under user’s attention.
Installation
CAUTION
a. The installation shall take place only on top of the metal surface or any material
with the fire resistant. Any place or location of high temperature, moist, oil and
gas, cotton fiber, metal powder and erosive gas shall be avoided.
b. If the product specification indicates IP00 (the protective level of the equipment
structure), any human contact is forbidden at the installation location to avoid the
electric shock. The option of installing AC reactor(ACL) or DC reactor(DCL) shall
be very cautious, too.
c. Please note the surrounding temperature shall not exceed 50°C when the
installation needs to be placed inside the control panel.
d. For the environment of storage and installation, please follow the instructions of
the environmental conditions illustrated in the sections of the common
specification of RM6 series (9426).
SAFETY PRECAUTION

Wiring
DANGER
a. Do Not conduct any wiring during the system power ON to avoid the electric shock.
b. R/L1,S/L2,T/L3 are power inputs (electric source terminals) and U/T1,V/T2,W/T3
are drive’s outputs connecting to a motor. Please Do Not connect these input and
output terminals to P, P○
+, N, N○ -, P1 and PR terminals.
c. Once the wiring is completed, the cover of the drive must be put back and must
seal the drive to avoid other’s accidental contact.
d. Do Not connect 200V series drives to the electric source of 346/380/415/440/
460/480V.
e. The main circuit and multi-function terminals cannot connect to ground (PE).
f. PE terminal must be exactly grounded. Ground the drive in compliance with
the NEC standard or local electrical code.
g. Please refer to the “section 2-3-4 Description of Terminals”for the screwing
torque of the wiring terminal.
h. Please refer to the national or local electric code for the appropriate spec. of the
cords and wires.
i. Please install an appropriate Molded Case Circuit Breaker (MCCB) or Fuse at
each path of power lines to a drive.
j. Please install the thermal relay between the individual motor and the drive when
using one drive to propel several motors.
k. Do Not connect power factor leading capacitor, surge absorber, or
non-three-phase motor to drive’s U/T1,V/T2,W/T3 side.
l. AC reactor(ACL) installation is required when the power capacity exceeds
500kVAor 10 times or more than the drive rated capacity.
m. After power off (30HP below models must wait at least 5 minutes; 40HP~75HP
models must wait at least 10 minutes; 100HP above models must wait at least
20 minutes). Do Not touch the drive or perform any unwiring actions before drive
indicator light (CHARGE) turns off. Use a multimeter with the DC voltage stage
to measure the cross voltage between P(+) and N(-) ports (DC bus voltage must
be less than 25V).
n. When the motor do the voltage-proof, insulation testing, unwiring the U/T1,V/T2,W/T3
terminal of drive at first.
CAUTION
a. The RM6 series (9426) are designed to drive a three-phase induction motor. Do
Not use for single-phase motor or other purposes.
b. The main circuit and control circuit must be wired separately; control circuit must
use a shielded or twisted-pair shielded wires to avoid possible interferences.
c. The control circuit must use a shielded or twisted-pair shielded wires to avoid
possible interferences and confirm the grounding.

Operation
DANGER
a. Do Not open or remove the cover while power is on or during the operation. Do
close up the cover before powering on the drive. Do Not remove the cover except
for wiring or periodic inspection when power off.
b. At the function F_078=1, the drive will automatically restart when the power is
restored. Stay away from the motor and machine.
c. At the function F_003=0 and F_001=0 or 1, the
OFF
RESET
key on keypad is ineffective.
Please use an emergency stop switch separately for safe operations.
d. The drive can produce high frequency outputs. Before adjusting the frequency,
please check the specifications of motor carefully to prevent the motor from
unexpected damages.
e. If any of the protective functions have been activated, and the start command is
set to terminal control (F_001=0 or 1). First remove the case and check if the all
running commands set to OFF. Then press the
OFF
RESET
key to release the alarm.
CAUTION
a. Do Not touch the heat sink or brake resistors due to the high heat.
b. Some models attach nylon rope when shipping. Do Not proceed the movement
or hanging the drive by this nylon rope to avoid unexpecting accident. Please
select a suitable rope to proceed the movement or hanging the drive.

Compliance with UL standards and CSAstandards (cUL-listed for Canada)
CAUTION
1. "Risk of Electric Shock"
Before starting or inspection, turn OFF the power and wait at least 5 minutes,
and check for residual voltage between terminal P and N with a multi-meter or
similar instrument has dropped to the safe level (50VDC or below), to avoid a
hazard of electric shock.
2. These devices are intended for use in Pollution Degree 2 environments.
3. Maximum surrounding air temperature 50C for RM6 series (9426).
4. Short circuit rating
"Suitable For Use On ACircuit Capable Of Delivering Not More Than 5000 rms
SymmetricalAmperes, 240V Maximum for 200V class." Models RM6 series
(9426) rated for 200V class input.
"Suitable For Use On ACircuit Capable Of Delivering Not More Than 5000 rms
SymmetricalAmperes, 480V Maximum for 400V class." Models RM6 series
(9426) rated for 400V class input.
"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 and any additional local codes."
5. Install UL certified branch circuit fuse between the power supply and the drive,
referring to the table below.
