Safety precautions

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.
• Turn off all power supplying this device before working on it.
• Always use a properly rated voltage sensing device to confirm that all power is off.
• Do not exceed the device’s ratings for maximum limits.
• Do not allow the total additive current flowing through the device to exceed 125 A.
• Do not use water or any liquid material to clean the product. Use a cleaning cloth to remove dirt. If dirt cannot be removed, contact local Technical Support representative.
  Failure to follow these instructions will result in death or serious injury.

Installation

Wiring

Recommended cable material: Copper wire with a compatible copper lug

Modbus RS-485

Power system wiring

A Fuses and disconnect switch

Clearly label the device’s disconnect circuit mechanism and install it within easy reach of the operator.

Fuses / circuit breakers must be:

• installed in accordance with all local and national electrical codes and standards, and
• rated for the installation voltage, available fault current, and sized for connected loads.

Fuse for neutral is required if the source neutral is not grounded.

**1PH

1PH multiple load with N

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Do not connect N’ to the load when setting the wiring type on the meter to 1PH4W Multi L-N.
Failure to follow these instructions will result in death or serious injury.
