DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the equipment in the presence of flammable gases or
fumes. Operation of any electrical equipment in such an environment
constitutes a definite safety hazard.
KEEP AWAY FROM LIVE CIRCUITS
Operating personnel must not remove equipment covers. Component
replacement and internal adjustment must be made by qualified
maintenance personnel. Do not replace components with the power cable
connected. Under certain conditions, dangerous voltages may exist even
with the power cable removed. To avoid injuries, always disconnect power
and discharge circuits before touching them.
DO NOT SERVICE OR ADJUST ALONE
Do not attempt internal service or adjustments unless another person,
capable of rendering first aid resuscitation, is present.
