- Do not modify the GLC unit. Doing so may cause a fire or an
electric shock.
- Do not use the GLC in an environment where flammable gasses
are present, since operating the GLC may cause an explosion.
Wiring Warnings:
- To prevent electric shock or equipment damage, prior to install-
ing or wiring the GLC, confirm that the GLC’s power cord is un-
plugged from the power supply.
- After completing any GLC wiring work, be sure the terminal block’s
protective plastic cover is reattached. If this cover is not reat-
tached, an electric shock could easily occur.
- Do not use power levels with the GLC that are outside of the
GLC’s specified power range. Doing so may cause a fire, electric
shock or damage the GLC.
- Do not operate or store the GLC in areas where flammable gas-
ses are present, since operating the GLC may cause an explo-
sion.
Operation and Maintenance Warnings:
- Do not touch a live power terminal. This could cause a shock or
machine malfunction.
- Due to the danger of an electric shock, confirm that the GLC’s
power cord is unplugged before either cleaning the GLC or at-
taching/detaching the power terminal block screws.
- When replacing the GLC’s backlight, be sure to unplug the unit’s
power cord to prevent a shock, and wear gloves to prevent being
burned.
- The GLC uses a lithium battery for backing up its internal clock
and control memory data. If the battery is incorrectly replaced
(i.e. the + and - sides are reversed), the battery may explode. There-
fore, before changing the battery, Pro-face recommends that you
contact your local GLC distributor for battery replacement instruc-
tions.
- Do not attempt to modify the GLC’s internal parts or wiring in any
way, since this may lead to either a shock or fire.
CAUTIONS
Wiring Layout Cautions:
- Be sure that all GLC input/output signal lines are isolated from all
power wiring or power cables, via a separate wiring duct. This is
to prevent excessive noise, which can cause a unit malfunction.
Installation Cautions:
- Be sure any data cable attached to a GLC connector is securely
attached. If the cable and connector pins do not all make com-
plete contact, incorrect input or output signals can result.e noise,
which can cause a unit malfunction.
