z Dangerous operations are noted in two levels: Warning and Caution.
Warning:
Failing to comply with the instructions suggested in a “Warning” will lead to a fatal injury or a death. (A
“fatal injury” means an injury, a scald, an electric shock, or a bone fracture,
leading to a persisting aftereffect, also means one requiring a long-term hospital treatment as an inpatient or
an outpatient.) An example follows:
Example:
When performing teach entry in which driving axes are allowed to move, do not stick head,
hands, or other parts of the body inside the mounter. Serious injury can result. Also make
sure non-operators are a safe distance from the machine.
Caution:
Failing to comply with the action suggested in a “Caution” will lead to a serious injury or a machine
damage. (A “serious injury” means an injury, a scald, or an electric shock, not requiring a long-term
hospital treatment as a inpatient or an outpatient.) An example follows:
Example:
Before starting teach entry, make sure no foreign obstacles are left in the mounter or tray
feeder. Otherwise, costly machine damage can occur.

Safety Guidelines
To prevent injury or machine damage in using the mounter, follow the safety guidelines stated below:
■ General
Only trained personnel, who are thoroughly familiar with the mounter, must use the mounter and enter
work area.
To prevent electric shock, never do tasks such as moving the machine, connect the machine to other
equipment, or servicing the machine when the power is on.
To prevent electric shock and machine damage, never touch terminals of electric components when the
power is on. Electric-shock labels are affixed to the machine covers under which the live electrical parts are
placed.
To prevent electric shock, ground the mounter.
Press immediately the emergency stop switch when the machine operates improperly.
To prevent electric shock, do not operate the mounter by wet hands.
■ Operation
The head assembly of the mounter moves at high speeds. To prevent injuries, do not enter head or hands
inside the operating mounter.
To prevent electric shock and machine damage, do not operate the mounter with live parts exposed.
To prevent electric shock and machine damage, do not touch parts in the control unit.
Turn off the mounter, if power failure occurs, to prevent sudden restarting that may cause personal injury or
machine damage.
■ Maintenance
Turn off the main switch and circuit breaker before servicing the machine.
Even after the main switch and circuit breaker are turned off, terminals for lead-in wires are still live. Do
not touch them to prevent electric shock.
Do not touch motors and motor drivers when they are hot.

Details
Unloading the mounter
If movable parts of the mounter move and lose a balance while unloading the mounter by a forklift, the
lifted mounter may slide down. It may cause to injury or machine damage.
When using a forklift, be sure to fasten movable parts securely in advance.
Installation
Improper installation of the mounter creates mechanical and electrical risks.
Be sure to install the mounter and connect the power supply in the correct way.
Line connection
The mounter is designed to use in a production line. If you use the mounter stand alone, please attach covers
at both the PCB entrance and exit by yourself to avoid a risk of injury of your hands. The covers should be
made conform to the following standard, EN294/JISB9707.
In the same way, even if the mounter is installed in your production line and there is an opening section you
can enter hands inside, make the cover equivalent to the following standard, EN294/JISB9707.
[EN294/JISB9707] Safety of machinery;
Safety distances to prevent danger zones being reached by the upper limbs
e: Opening width Opening shape
Rectangle (square)
6 < e ≤ 8 ⇒ Safety distance ≥ 20(15)
8 < e ≤ 10 ⇒ Safety distance ≥ 80(25)
10 < e ≤ 12 ⇒ Safety distance ≥ 100(80)
12 < e ≤ 20 ⇒ Safety distance ≥ 120(120)
Feeder bank
Do not put you hands between feeders on the feeder bank. It may cause injury. Please purchase dummy
feeders to fill the vacant feeder stations to prevent from putting your hands in. Or make the cover equivalent
to the standard, EN294/JISB9707.
Electric shock
Even if you turn off the main switch of the mounter, there is residual voltage in the primary power supply
and the wirings between the terminal assembly (XB11) and the main switch (QS11).
Do not remove the covers or disassembling the mounter. It may cause electric shock.
UPS
Even if you turn off the main switch of the mounter, the optional UPS remains residual voltage. Do not
remove the covers or disassemble the mounter. It may cause electric shock.
Regenerative resistor
The regenerative resistor can be hot. Do not remove the covers or disassemble the mounter. Touching the
generation resistor or the heatsink may cause burn injury.
