2. Installation

This section covers the unique installation and wiring requirements of the Digital Futronic VIII system.

Installation and wiring is normally performed in the field by others. All interconnect wiring between

M2CP and VFC is installed at the factory for Separate Control Module (SCM) and internal mounted

VFC systems. Remote mounted VFC systems must be wired at time of installation. Setup and

calibration of the unit and programming of the VFC are also performed at the factory. If adjustments to

setup and calibration become necessary during or after installation, the drive specific appendix should

be consulted. Field communication and control wiring is connected to terminals in the M2CP package.

This section provides instructions on required field wire termination. Refer to Manual E796 for

instructions on setting mechanical limit and torque switches. Valve adaptation and mounting is normally

performed by others. Some general guidelines on conduit installation in preparation for wiring is

covered in this section. Installation must be performed in accordance with the National Electrical Code

(NEC) and any local codes which may apply. An electrical disconnect and/or circuit breaker is required

to disconnect power during installation and maintenance.

2.1. Conduit Entries

Separate conduits must be installed for power wiring and low voltage control signal wiring including

communication network cables. All conduit entries should be made at the bottom or lowest point of the

electrical enclosure. If any conduit run is above the level of the electrical enclosure, it must have a drain

installed at a point lower than the electrical enclosure to prevent piping water into the enclosure. If it is

necessary to enter the enclosure at the top, a drain must be installed at the bottom of the enclosure to

prevent water from accumulating inside.

Conduit for motor power wires should enter at the left most conduit entry nearest the motor of the

M2CP enclosure attached to the actuator. If redundant communication cables are installed, these

cables should use separate conduits with separate entries to prevent loss of both communication

channels in case of an accident.
