5.4 WIRING GUIDELINES
• The electrical code requires that an approved circuit disconnecting device be installed in the
incoming AC supply circuit. Mounted in a location readily accessible to personnel
installing or servicing this equipment.
• Power factor correcting capacitors MUST NOT be connected to the OPAL output. If
desired, they may be added ahead of the starter. Capacitors can be connected before
starting or after the motor has reached full speed.
• In-line contactors are not required; however they can be used on the line side or the motor
side without detriment to the starter. It is recommended that the contactor be sequenced to
open and close under no-load conditions to prolong the life of the contacts.
• Size the power wiring as per local code. On long wire runs it is recommended to use a
larger wire size.
• All three phases of the incoming power wires must pass through the same hole in the
enclosure. This rule also applies to all phases of the outgoing or motor wires.
• If an electro-mechanical brake is used in the system, it must be powered from the line side
of the starter, to ensure full voltage to the brake.
