Installation Inspection

Prior to system start-up or trouble shooting, the entire system should be visually inspected. The following are guidelines for
that inspection.

7.5.1 Controller Installation

• Controller installed in conformance to instruction manual recommendations.
• AC power is correctly grounded.
• Hot AC and relay connections have safety covers installed.

7.5.2 Cabling Installation

• All splices are soldered or via terminal block.
• Cabling is away from sources of electrical noise or RFI where possible.

7.5.3 Sensor Module Installation

• Module installation in conformance with this manual.
• Modules accessible for calibration.
• Wiring terminations clean and correct.

7.5.4 Moisture Traps and Rainshields

• Conduit seals and drains installed to avoid moisture build up in electronics enclosure. Water accumulation in sensor
module enclosures is a major cause of damage and system failures - take precautions to seal electrical conduits and
provide moisture traps and drains to avoid water damage.
• Model 5311-02 rain shield is recommended for installation in wet areas.

7.5.5 Standard Voltages

• Regulated DC voltage to be applied to the sensor module must be between 10 VDC and 30 VDC.
