Connections
DECS-400 connections are dependent on the application and excitation scheme used. Observe the
following guidelines when making DECS-400 connections.
•
All inputs or outputs may not be used in a given installation.
•
Incorrect wiring may result in damage to the unit.
•
Applying incorrect operating power or sensing current may result in damage to the unit. Compare
the style number of your unit with the style chart before applying operating power.
Note
Be sure that the DECS-400 is hard-wired to earth ground with no
smaller than 12 AWG copper wire attached to the ground terminal on
the rear of the case. When the unit is configured in a system with other
devices, it is recommended that each unit be grounded with a
separate lead.
DECS-400 Terminations
DECS-400 terminations consist of screw terminals, D-type connectors, an RJ-11 jack, and an RJ-45 jack.
Front Panel Terminations
Front panel terminations consist of a nine-pin, female, D-type connector that is intended for short-term,
RS-232 serial communication with a PC. The location of the front panel communication port is shown in
the Human-Machine Interface chapter.
Rear Panel Terminations
Current sensing connections are made through #8 screw terminals at terminals A1 through A8. The Field
Isolation Module connects to a 15-pin, female, D-type connector designated as P1. DECS-400 modem
connections are provided by an RJ-11 jack (J1). Connections for Ethernet communication are made
through an RJ-45 jack (Com 3). All other connections are made through #6 screw terminals. Rear panel
terminations are illustrated in Figure 91.
