CAUTION WHEN HANDLINGFOR YOUR SAFE USAGE

A. Prior To Use

CAUTION : Improper handling of the conveyor may result in physical injury or damage!
■Transport and assembly
When transporting and assembling the conveyor, pay special attention not to drop it in order toavoid physical injury or damage. When lifting by crane, pay attention to the balance of the conveyor.
■Earth and leakage breaker
Ensure the conveyor is connected to earth at all times to prevent electric shock. Also ensure thatan earth leakage breaker is connected to the power supply.
■Emergency stop
Install an emergency stop device to immediately stop the conveyor in emergency.
■Start alarm
If it is not possible to supervise the operation of the full length of the conveyor from the operating
position, install a start alarm for increased safety.
■Keep the conveyor dry at all times
Do NOT use the conveyor in wet or humid areas. Do NOT splash liquids onto the conveyor. DoNOT use or leave the conveyor outdoors. The machine is not waterproof. Do NOT touch electricalparts with wet hands.
■Do NOT use in an explosive atmosphere(Avoid explosive gas, explosive dust, etc.)□ When using in a high or inclined position:■Lower cover and guard
Install the optional lower cover or guard in order to prevent entry under the conveyor.
■Guide rail, top and side covers
To prevent objects from falling off the conveyor, install the optional guide rail, top and/or sidecovers.
■Braking system
When using the conveyor on an incline, it is recommended that an optional braking system beinstalled, in order to prevent reverse or other incorrect running of the conveyor.
■Environmental conditions
Ambient temperature：0℃ to +40℃
Ambient humidity：RH 85% max(Avoid condensation)
Atmosphere：Indoor(Avoid corrosive gases, dust, etc.)
Elevation：1,000m or less
NOTE：
●Using the conveyor in a strong electric field (eg near broadcasting devices or high- frequency weldingmachinery/equipment) could cause the conveyor to malfunction. In this case, install the conveyor at asufficient distance. Alternatively shield completely to avoid any interference with the conveyor.
●Using an inverter to this machine could cause other machines to get effects of high-frequency. In thiscase, install the conveyor at a sufficient distance or shield completely.

4B. During Operation

WARNING：Improper handling of the conveyor could result in serious physical injury or damage!
■Do NOT touch the conveyor when it is running
There is considerable risk of being caught and injured by the conveyor.
■Do NOT ride on or climb on the conveyor／Do NOT go under the conveyor
There is considerable risk of falling or being caught and injured by the conveyor.

CAUTION：Improper handling of the conveyor may result in physical injury or damage!
■Beware of entanglement
When working close to the conveyor, take care not to get caught in the conveyor. There isconsiderable risk of being injured by the conveyor.
■Do NOT remove safety covers
There is a risk of getting caught in the rotating parts such as pulleys. Only remove in case ofmaintenance or inspection.
■Do NOT start the conveyor while it is loaded
The motor may become damaged due to overload. Additionally, the motors of variable-speed typemachines may burn out as a result of running at excessively low speeds forlong periods. Use the conveyor within the specifications, indicated in the instructions for use, andin the catalogue.
■Do NOT apply force to ends of conveyor
Do NOT press down on, or hang off the sides of the conveyor. Injury may result from a toppling
conveyor.
■Secure the conveyor to the floor/ground
When using the conveyor, be sure to secure it to the floor/ground with anchor bolts etc. toprevent it from toppling irrespective of indoor use or outdoor use.

C. After Use

CAUTION：Improper handling of the conveyor may result in physical injury or damage!
■Switch off the power after use
Ensure that the power is switched off when carrying out relocation, inspection, cleaning, etc. ofthe conveyor, otherwise there is a risk that the conveyor could start unexpectedly. When leaving
the conveyor unused for a long period, take plug out of the outlet /connector to prevent electric
shock or leakage.

NOTE：1. Always use in accordance with the Occupational Safety and Health Act.
2. If the owner modifies the conveyor, any ill effects will fall outside the conditions of the guarantee.

Instruction

DB-3■ DO NOT PASS UNDER THE CONVEYOR
There is considerable risk of falling or being caught andinjured by the conveyor.

DC-2■ KEEP HANDS OUT WHILE MACHINE IS RUNNING
There is considerable risk of being caught and injured bythe conveyor.
■ DO NOT CLIMB ON CONVEYOR
There is considerable risk of falling or being caught andinjured by the conveyor.

CAUTIONorWARNING

CA-2■ ALWAYS CONNECT TO EARTH
Ensure the conveyor is connected to earth at all times toprevent electric shock.
■ DISCONNECT POWER BEFORE SERVICING
Ensure that the power is switched off when carrying out
relocation, inspection, cleaning, etc. of the conveyor,
otherwise there is a risk that conveyor may start
unexpectedly.

6CF-2■ DO NOT GET CAUGHT IN MACHINE
When working close to the conveyor, take care not to getcaught in it. There is a risk of being injured by theconveyor.

CE-2■ HOT SURFACE, DO NOT TOUCH
When the conveyor is running or immediately after it stops,
do NOT touch the motor, control unit, etc. There is a riskof getting burned or injured by the heat.

RUNNING THE CONVEYOR

3-1. BE SURE TO GROUND MACHINE BEFORE OPERATION
200V three-phase power source: Standard machine has only lead wire terminal. Before operation,confirm position and function of emergency stop and that there is no dangerous place around conveyor
and its movable parts.

3-2. RUNNING THE CONVEYOR
Operate inverter as follows:
NOTE: Before operation, remove cover of inverter operating panel. Reinstall the cover after operation.
1. Turn on power supply and ensure that EXT indicator(*1) is illuminated. Then press PU/EXT key(*2)
and ensure PU indicator(*3) is illuminated. (PU operation mode)
2. To start conveyor, press RUN key(*4); to stop conveyor, press STOP/RESET key(*5).
3. To set speed, turn M-dial(*6) until the monitor(*8) shows intended frequency. Then press SET key(*7).
(Only turning M-dial does not change speed. To complete speed setting, be sure to press SET key.)
4. It is possible to change direction of belt travel or make external control by setting parameter. For
details, refer to inverter instruction manual, appendix.
