V. ELECTRICAL INSTALLATION
WARNING: VERY HIGH VOLTAGE IS PRESENT. REMOVE POWER FROM THE UNIT BEFORE
INSTALLING, REMOVING, OR MAKING ADJUSTMENTS
GENERAL SAFETY
When using electrical equipment, you should always follow basic safety precautions, including the following:
• The installation and wiring of this product must comply with all national, federal, state, municipal, and
local codes that apply.
• Properly ground the enclosure to an adequate earth ground.
• Do not modify any factory wiring. Connections should only be made to the terminals described in this section.
• All connections to the unit must use conductors with an insulation rating of 300 V minimum, rated for
212º F (105º C), a minimum flammability rating of VW-1, and be of appropriate gauge for the voltage and
current required (see specifications).
• Do not allow moisture to enter the electronics enclosure. Conduit should slope downward from the unit
housing. Install drip loops and seal conduit with silicone rubber product.
DISCONNECT REQUIREMENTS FOR PERMANENTLY INSTALLED EQUIPMENT
A dedicated disconnecting device (circuit breaker) must be provided for the proper installation of the unit. If
independent circuits are used for power input and main relay outputs, individual disconnects are required.
Disconnects must meet the following requirements:
• Located in close proximity to the device
• Easily accessible to the operator
• Appropriately marked as the disconnect for the device and associated circuit
• Sized appropriately to the requirements of the protected circuit (See specifications)
WIRING TRANSDUCER AND TEMPERATURE PROBE TO JUNCTION BOX
Avoid cutting the transducer cable if possible.
See Figure 4: Wiring Transducers to Controller.
1. Transducer cable — connect the cable to the junction box terminals.
2. Optional temperature probe — connect the cable to the junction box terminals.
CAUTION: DO NOT RUN OTHER CABLES OR WIRES THROUGH THE SAME CONDUIT WITH
THE TRANSDUCER AND TEMPERATURE PROBE CABLES. DO NOT ROUTE THE TRANSDUCER/
JUNCTION BOX CABLES IN THE SAME CONDUIT WITH THE SERIAL DATA BUS CABLES.
