2.0 Installation and Wiring
This section describes the procedures for installing the UMC 600IS indicator, including load cell, digital input,
and serial communications cabling.

2.1 Hazardous Area Installation of the UMC 600IS
The following information is provided to help the installer use the correct conduit and load cells for installation
of the UMC 600IS.
Drawings Required for this Installation
Table 2-1 shows the UMC 600IS control drawing numbers and titles. The UMC 600IS drawings are included in
the back of this manual.
2.1.1 Conduit System (Supplied by Customer)
Power Supply to Indicator
Conduit is not required for this installation. However,
a separate conduit system is recommended. The type
suggested for this application is 3/4 inch rigid steel
conduit with pull boxes located at required intervals.
The conduit provides additional noise protection for
the low level signals, while automatically complying
with the requirements for 2 inch separation between
intrinsically safe circuits and other electrical cables.
Conduit seals are required where a gas tight seal is
required between the hazardous area and the safe area.
To protect the watertight integrity of the I/O barrier
and junction box, the conduit should terminate
adjacent to the respective enclosure with a union
providing the proper thread to accept a Hubbel or
Crouse Hinds cord connector for the cable to exit the
conduit. All conduit, fittings, and conduit accessories
are provided and installed by the customer.
NOTE: The customer is responsible for the correct
installation of all conduit seals in compliance with all
National Electrical Code regulations.
AC Line Voltage Feed
The installer must comply with Condec installation
drawings as well as the National Electrical Code for
installation of equipment in hazardous areas (NEC
Article 504,
Instrinsically Safe Systems ).
