20 Install and Wire the Panel
Incoming/Outgoing Wire
Installation Allowable incoming and outgoing voltages can range from 0V DC to 24V DC.
For details about field wiring apparatus, refer to the control drawing in the
DataSite Hardware User Manual, publication
1758-UM001 .
Install Conduit
When installing conduit, make sure it is installed according to all applicable
codes and standards. This is to ensure that water and moisture cannot enter or
accumulate in the DataSite controller enclosure.
Conduits must be installed so they are compatible with the UL rating of the
DataSite controller. It is recommended that the conduit be positioned to
minimize cable bending and maintain relative vertical alignment to incoming
connections.
Install Cable
Install cable when the ambient temperature is above freezing (0 °C or 32 °F),
unless it is suitable for installation at temperatures below freezing. This will
help prevent cable insulation from cracking or splitting.
DataSite controllers are rated for use with 75 °C (167 °F) cable. Cable must be
sized using 75 °C (167 °F) column in NEC Table 310–16 (NEC 2005 Edition).
IMPORTANT
Any conduit or cable entering or leaving the DataSite
configured panel which is not deemed non-incendive must be
held in conduit to maintain the UL Class I Division 2 Listing of
that control panel.
ATTENTION
When installing the DataSite configured panel within a Class I
Division 2, hazardous location, special installation of conduit
and cable must be considered. Refer to NEC 2005 article 501 for
details on proper installation of the conduit, cable, and box
fittings.
TIP
To verify field wiring connection points, refer to the wiring
diagrams in the DataSite Hardware User Manual, publication
1758-UM001 .
