HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• While removing or installing panels and covers, ensure that they do not contact an energized bus.
• NEVER bypass external fusing.
• NEVER short the secondary of a potential transformer.
• Before closing covers and doors, carefully inspect the work area and remove any tools, wire scraps or
other objects that may
have been left inside the equipment.
• Do not exceed the product's ratings or maximum limits.
• Turn off all power supply equipment before working on or inside equipment.
• Use a properly rated voltage sensing device to cofirm that power is off.
• Treat all measurement circuits and CT connections as energized live.
Failure to follow these instructions will result in death or serious injury.
ESD-SENSITIVE DEVICES
Observe handling precautions for static sensitive devices.
Failure to follow this instruction can result in damaged circuitry and loss of factory warranty.
For all steps in this section, when tightening terminals, apply the correct torque.
Removable connectors on main board: 4.4 to 5.3 in-lb (0.5 to 0.6 N-m). See Figure 8.
Figure 8
1. Connect 2-wire 90 to 277 Vac power to the main power terminals. Observe polarity. Connect voltage lines to the voltage taps
(Figure 13). Provide overcurrent protection and disconnecting means to protect the wiring. Use Veris AH02, AH03, AH04, or
equivalent. Suggested: 0.5 A, time delay fuses.
Wiring configurations are listed below.

120/240V Delta High Leg (where the center tap of one of the three phase-to-phase transformers is grounded): the E34 supports
these applications, as long as the line-to neutral voltage (especially of the High Leg) does not exceed 300 Vac (as in North American
120/240 V High Leg Delta configurations).
