SAFETY SUMMARY
The following safety precautions must be observed during all phases of operation, service, and
maintenance of this equipment. Failure to comply with these precautions or with specific
warnings elsewhere in the manual violates safety standards associated with the design and
intended use of this equipment. This manual forms an integral part of the equipment and must
be available to operating personnel.
GROUND THE EQUIPMENT
This equipment may have high leakage current to chassis due to EMI filtering requirements. To
minimize shock hazard, the equipment chassis(s) must be connected to an electrical safety ground.
This equipment is supplied with a three conductor line connection for single phase applications
and/or a five wire connection for three phase applications. Both types include an earth terminal
intended for safety ground connections. In addition, isolated installation sites may require neutral to
earth connections as per NEC section 250 (National Electrical Code). Refer installation to licensed
electrician or other qualified personnel.
DO NOT OPERATE IN EXPLOSIVE ATMOSPHERE
Do not operate the equipment in the presence of flammable gases or fumes. Operation of any
electrical instrument 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
adjustments must be made by qualified maintenance personnel. Do not replace components with
power applied. Under certain conditions, dangerous voltage may exist even with the power removed.
To avoid injuries, always disconnect power and discharge circuits before touching them. During
normal operation the operator does not have access to internal hazardous voltages. However,
depending on the user’s application configuration,
HIGH VOLTAGES HAZARDOUS TO
HUMAN SAFETY
may be normally generated at the output terminals. The customer/user must
insure that the output power lines are labeled properly as to the safety hazard and that any
inadvertent contact is eliminated.
DO NOT SERVICE OR ADJUST ALONE
Do not attempt internal service or adjustment unless another person, capable of rendering first
aid and resuscitation is present.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT
Because of the danger of introducing additional hazards, do not install substitute parts or perform
any unauthorized modification to this equipment. Contact Behlman Electronics for proper
replacement parts and specific service information.
