Compliance with European Union Electromagnetic Compatibility Standards

B-13

The external motor wiring must be run in a screened cable or continuous conductive
conduit. The motor shunt field and armature leads can be run together in the same
cable. A ground wire must be run that bonds the motor to the system star ground.
Refer to figure B.10 for proper connection of the conduit screen and bonding wire.

Motor cable length is a major contributor to common mode conducted emissions.
FlexPak mains filters are sized for up to 75 meters (250 feet) of screened motor power
cables (total installed length). If your installation requires a greater length, contact
Reliance Electric.

B.5.6 Wiring the Kits

The FlexPak 3000 has a number of option kits. The kits listed in table B.3 are EMC
benign - they have no impact on the EMC compliance of the product if properly
installed. See the appropriate kit I/Ms for installation and wiring information.

Instructions for wiring the I/O Expansion board, Dynamic Braking kit, and Pulse and
AC Tachometer Feedback kits for CE96 compliance follow.

B.5.6.1 I/O Expansion Board (Model Number 914FK0101)

Wiring connected to this board must be run in screened cable or continuous
conductive conduit.

B.5.6.2 Dynamic Braking Kit (Model Numbers 908FK, 909FK, 912FK, and 913FK)

The standard Reliance FlexPak dynamic braking resistor kits can be installed on the
top of the electrical cabinet either in an expanded sheet-metal enclosure or solid-plate
enclosure without impact on compliance. The kit enclosure can be used for the
resistors and dynamic braking circuit.

The DC motor armature leads to the resistor enclosure are to be dressed close to the
mounting panel as shown in figure B.11.
