ELECTROSTATIC
DISCHARGE
(ESD)
PRECAUTIONS
PROCEDURE
FURNACE RELIABILITY
HAZARD
Failure
to follow
this
caution
may
result
in furnace
component damage.
Electrostatic
discharge can affect electronic components.
Follow
the
Electrostatic
Discharge
Precautions
Procedure
listed below during furnace
installation
and
servicing
to
protect
the
furnace
electronic
control.
Precautions
will prevent
electrostatic
discharges
from
personnel
and hand tools which are held during the
procedure. These precautions will help to avoid exposing
the control
to electrostatic
discharge
by putting
the
furnace,
the
control,
and
the
person
at the
same
electrostatic potential.
1. Disconnect
all power to the furnace. Multiple discon-
nects
may
be
required.
DO
NOT
TOUCH
THE
CONTROL
OR ANY WIRE CONNECTED
TO THE
CONTROL PRIOR TO DISCHARGING
YOUR BODY'S
ELECTROSTATIC
CHARGE TO GROUND.
2. Firmly touch the clean, unpainted, metal surface of the
furnace chassis which is close to the control. Tools
held in a person's hand during grounding wilt be satis-
factorily discharged.
3. After touching the chassis, you may proceed to service
the control or connecting wires as long as you do noth-
ing to recharge your body with static electricity (for ex-
ample; DO NOT move or shuffle your feet, do not touch
ungrounded objects, etc.).
4. If you touch ungrounded
objects (and recharge
your
body with static electricity), firmly touch a clean, un-
painted
metal surface
of the furnace
again
before
touching control or wires.
5. Use this procedure
for installed and uninstatled
(un-
grounded) furnaces.
6. Before removing a new control from its container, dis-
charge your body's electrostatic
charge to ground to
protect the control from damage. If the control is to be
installed in a furnace, follow items 1 through 4 before
bringing the control or yourself in contact with the fur-
nace. Put all used and new controls into containers be-
fore touching ungrounded objects.
7. An
ESD
service
kit
(available
from
commercial
sources) may also be used to prevent ESD damage.
