|The partition plate is needed for isolating the intrinsically safe area from the non-intrinsically safe area inside the cabinet.|
|Each set of 4 galvanic isolators requires a Galvanic Isolator Wiring Set and a data logger of its own.|
|You can install only one type of device or measurement point (PDT101 transmitters, analog input channels, safety barriers, or galvanic isolators) per row in the cabinet.|
In cabinet models with 5 to 8 data loggers, you need 2 serial port servers.
One serial port server controls the traffic of maximum 4 data loggers.
|Make sure to number the data loggers as well as the cable sets and wires in the Galvanic Isolator Wiring Set before you install and connect them.|
Follow the steps below to add new galvanic isolators to an existing set of devices in CAB100B. Refer to CAB100B layout diagrams when planning the installation.
For instructions on introducing galvanic isolators as new devices to an empty DIN rail in the cabinet, see Adding galvanic isolators as new modules to CAB100B.
The Galvanic Isolator Wiring Set consist of wiring for 4 devices. Any unused wires in the Wiring Set have been placed in the cable duct at the factory. If you have, for example, 3 isolators installed on a DIN rail, and want to complete the set by installing a fourth one, use the existing isolator wires present in the cable duct.
De-energize the cabinet:
Switch off mains power and the circuit breaker located inside the cabinet.
Disconnect the galvanic isolator power wire connector from the power block located on the right-hand side of the cabinet.
- Switch off mains power and the circuit breaker located inside the cabinet.
- Remove the cable duct cover above the galvanic isolators.
Mount the DL4000 data logger (or loggers), as shown in the following steps.
Each set of 4 galvanic isolators requires a data logger of its own. If you are installing the second, third, or fourth isolator to complete a set of 4, the steps to mount a new data logger are not relevant, as you can connect the new isolator(s) to the existing data logger.
Assemble the data logger holder.
- Place the data logger in the logger holder.
- Fit the cover into place.
Tighten the screw by hand.
Connect the logger data cable to the RS-232 serial port in the data logger.
Use a small flat head screwdriver to tighten the screw attached to the connector.
