Field Wiring the TMD IV
All wiring, except as noted, is the responsibility of the customer. Follow the field wiring diagram for your
system or refer to the Field Wiring Diagram D07468F-E001 to connect system wiring to the CPU board in the
control unit.
WARNING.
All wiring must be done in accordance with field wiring diagrams, the National Electrical
Code, and all local electrical codes. Do not route cables through the same conduit with power cables
or any large source of electrical noise.
Critical Wiring Conditions
Be sure to observe the following critical wiring conditions to ensure proper connection of your detector:
•
Ensure main power is OFF.
•
High voltage (>30 V) and low voltage (< 30 V) cables must be routed through different areas of the
control unit enclosure (see Figure 2-1).
•
Earth ground all enclosures and conduit. A ground connection between all conduits is required.
•
Stranded, rather than solid, wire should be used. This wiring should be long enough, and routed, to
allow the chassis to be removed from the front for servicing.
•
Connect the shields only where shown.
•
Never use a “megger” to check the wiring.
•
A readily accessible disconnect device (maximum 20A, minimum 5A) shall be incorporated in the field
wiring. This disconnect should be in easy reach of the operator and it must be marked as the
disconnecting device for the equipment, see fusing requirements.
•
All conduits should enter the bottom of the enclosure. Do not run conduit through the top or sides of
the enclosure.
Field Wiring Procedure
Follow all cable number specifications on the Field Wiring Diagram (D07468F-E001) when connecting wiring to
the CPU board. Figure 2-2 shows the locations of the terminal blocks.
