3. Mounting and Wiring Procedures

3.1. Installation and wiring guidelines

• Locate instrument away from sources of water, heat, humidity, and dust or

provide a suitable enclosure to protect it from these elements.

• Locate the instrument away from sources of electrical noise such as , but not

limited to: SCRs, triacs, buzzers, horns, motors, welding equipment,

contactors, heavy current relays, and other noise generating electrical

equipment.

• Use a grounded metal enclosure to protect the instrument from radiated

electrical noise and other magnetic influences.

• Separate low voltage signal and control wiring from switching and power

wiring. Plan cabinet and panel wiring so that power and relay wiring are

dressed to one side and low-level signals are dressed to the other. Plan wiring

to maintain separation at entry to, and egress from the enclosure.
