CCW-R-2**B INSTRUCTION MANUAL 1 SAFETY PRECAUTIONS
1-3
1.3 General Precautions
This section describes the general precautions, which need to be observed for safe device operations.
When working on the device with the main body cover open, do not touch the
current-carrying parts.
Failure to do so may cause an electrical shock.
All electrical work must be performed by electrical contractors or licensed electrical
engineering technicians.
All electrical maintenance and inspections must be performed by qualified
maintenance electricians.
Maintenance and inspections performed by an unqualified electrician may result in
an electrical shock and device malfunction.
Do not touch any switches or buttons with wet hands.
Doing so may cause an electrical shock if the device is not properly grounded or if
there is an electric leakage.
Do not operate the device with the covers removed.
Before operating the device, make sure that each cover is installed properly.
Failure to do so may result in injuries caused by touching the moving parts during
operations.
Operators must tie up long hair and wear a hat, proper clothing and shoes before
operation.
Failure to do so may result in injuries caused by being caught in the rolling portions
of the device.
For maintenance and inspections, unless instructed, the operator must turn OFF and
lock the main power switch and keep the key in his possession during the work.
This is to prevent other personnel from starting the device, which may cause an
electrical shock or injury.
When performing maintenance and inspections, turn the main power switch OFF
and wait at least three minutes before starting the work. The device’s main body has
a portion where electricity is stored even after the power is shut off. When other
devices are connected before and after this device, shut off the power for all of the
devices.
Failure to do so may cause an electrical shock.
When maintenance and inspections need to be performed with the main power
switch turned ON, clearly indicate to other operators that maintenance and
inspections are in progress in order to prevent other operators from accidentally
starting the device.
