• Use only factory documented components for repair. Tampering or unauthorized substitution of

parts and procedures can affect the performance and cause unsafe operation of your process.

WARNING

Electrical shock

Making cable connections to and servicing this instrument require access to shock hazard level
voltages, which can cause death or serious injury.

Equipment protected throughout by double insulation.
Disconnect main power and relay contacts wired to separate power sources before servicing.
Do not operate or energize instrument with case open.
Non-metallic cable strain reliefs do not provide grounding between conduit connections. Use

grounding type bushings and jumper wires.
Electrical installation must be in accordance with the National Electrical Code (ANSI/NFPA-70)

and/or any other national or local codes.
Unused cable conduit entries must be securely sealed by non-flammable closures to provide

exposure integrity in compliance with personal safety and environmental protection
requirements. Unused conduit openings must be sealed with NEMA 4X or IP65 conduit plugs to
maintain the ingress protection rating (IP65).

Operate only with front and rear panels fastened and in place over terminal area.
Safety and performance require that this instrument be connected and properly grounded

through a three-wire power source.

WARNING

This product is not intended for use in the light industrial, residential, or commercial
environments per the instrument's certification to EN50081-2.

CAUTION

Radio interference

This product generates, uses, and can radiate radio frequency energy and thus can cause radio
communication interference. Improper installation or operation may increase such interference. As
temporarily permitted by regulation, this unit has not been tested for compliance within the limits of
Class A computing devices, pursuant to Subpart J of Part 15 of FCC rules, which are designed to provide
reasonable protection against such interference.

Operation of this equipment in a residential area may cause interference, in which case the
operator, at his own expense, will be required to take whatever measures may be required to
correct the interference.

WARNING

Physical access

Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end
users’ equipment. This could be intentional or unintentional and needs to be protected against.

Physical security is an important part of any security program and fundamental to protecting your
system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for
all systems used within the facility.
