Wiring Connections 2.6
All wiring connections are typically made to the instrument at the time of installation. Connec-
tions should be made at the terminal blocks , two 12 gauge wires maximum. Terminal blocks
are designated TB1 through TB13. See Figure 2-4 for the terminal block locations (SPST
Relay Board shown).

2.6.1 ELECTRICAL CONDUIT OPENINGS
The instrument case will have 3 or 4 conduit openings, depending upon the number of outputs
specified. To help mimumize electrical noise that may adversely affect the operation of the
instrument the wires indicated below should be routed through the conduit opening specified.
See Figure 2-1 (page 8) for conduit opening locations.
EC1- AC Power Input
EC2- Analog input and mADC outputs
EC3- SPST, SPDT relay or SSR driver outputs
EC4- SPST, SPDT relay or SSR driver outputs (provided when > 4 relays & SSR Drivers
are specified)
Unused conduit openings should be sealed.
2.6.2 AC POWER WIRING CONNECTIONS
WARNING: Avoid electrical shock. AC power wiring must not be connected at the source
distribution panel until all wiring connections are completed.
