DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E in the USA or applicable local standards.
• This equipment must only be installed and serviced by qualified electrical personnel.
• Turn off all power supplying equipment before working on or inside the equipment.
• Product may use multiple voltage/power sources. Disconnect ALL sources before servicing.
• Use a properly rated voltage sensing device to confirm that power is off. DO NOT depend on this product for voltage indication.
• Current transformer secondaries must be shorted or connected to a burden at all times.
• Products rated only for basic insulation must be installed on insulated conductors.
• Replace all doors, covers and protective devices before powering the equipment.
• This product must be installed inside a suitable fire and electrical enclosure.
• This product is not intended for life or safety applications.
  Failure to follow these instructions will result in death or serious injury.

WARNING

RISK OF INJURY OR EQUIPMENT DAMAGE

• Do not apply current transducers to circuits having a phase-to-phase voltage greater than their voltage rating unless adequate additional insulation is applied between the primary conductor and the current transducers.
• To reduce the risk of electric shock, always open or disconnect circuit from power-distribution system (or service) of building before installing of servicing current transformers.
• The current transformers may not be installed in equipment where they exceed 75 percent of the wiring space of any cross-sectional area within the equipment.
•  Restrict installation of current transformer in an area where it would block ventilation openings.
• Restrict installation of current transformer in area of breaker arc venting.
• Not suitable for Class 2 wiring methods and Not intended for connection to Class 2 equipment.
• Secure current transformer and route conductors so that they do not directly contact live terminals or bus (optional).

Failure to follow these instructions may result in injury, fire or equipment damage.

Note: Do not use the product if it is damaged. Contact a Veris customer service representative for support.

Product Overview

The H681x-V series of 1 volt and 0.333 volt split-core current transformers (CTs) provide secondary AC voltage proportional to the primary (sensed) current. For use with power meters, data loggers, chart recorders, and other instruments, the H681x-V series CTs provide a cost-effective means to transform electrical service amperages to a voltage compatible with monitoring equipment.

Installation

Installation must be performed by a qualified electrician.
Disconnect and lock out power to the electrical panel.

• Connect the secondary leads to the burden or test switching/shorting bar. The white wire is the x1 lead.

•  Depress the tabs on one end of the CT to open it. Check the core ends on both sections of the CT to ensure there is no rust or debris in the closure areas.

• Slip the CT over the primary leads. Note labeling on the product indicating “source side.”

• Close and latch the CT, and mount it securely.
  **WARNING
  RISK OF INJURY OR EQUIPMENT DAMAGE
  • Secure the I-bar to U-bar so that it remains in place. Close the CT with a suitable cable tie.
  Failure to follow these instructions may result in injury, fire or equipment damage.
  Note:** These split-core devices have a detachable I-bar. If the I-bar is removed, re-orient it according to the markings on the core surface, then re- attach it. In any application where fault currents can exceed 20 times the rated current of the CT, use wire ties or similar fasteners to secure both sides of the I-bar to the CT housing.

• Reconnect power to the panel.
  Note: An optional mounting kit is available for these devices (Veris part number AH06).

Ratings

These products provide basic insulation to 600 Vac between the sensed conductor and the output leads. For reinforced applications, the installer must provide appropriate insulation. Reinforced insulation is provided for applications to 300 Vac between the sensed conductor and the output leads.
