PF1352 USER MANUAL REV A 12/21/15
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.
