2. Run conduit or armored braided cable from the power distribution
panel to the conduit hub on the right side of the analyzer enclosure
labeled for power input.
3. For AC systems, pull ground, neutral (N) and L1 wires into the
electronics enclosure. Refer to Figure 2–2.
For DC systems, pull VI +, – and ground wires into the electronics
enclosure. Refer to Figure 2–2.
4. Strip back the jacket and/or insulation of the wires just enough to
connect to the power terminal block.
5. Connect the main ground wire to the protection ground terminal
marked .
6. Close and tighten the analyzer enclosure door.
Conduit seals or Ex e cable gland should be used where
appropriate in compliance with local regulations.
Because the breaker in the power distribution panel or switch will
be the primary means of disconnecting the power from the
analyzer, the power distribution panel should be located in close
proximity to the equipment and within easy reach of the operator,
or within 10 feet of the analyzer.
The electrical installation to which the apparatus is connected
must be protected against transients. The protective device has
to be set at a level not exceeding 140% of the peak rated voltage
values at the power supply terminals.
An approved switch or circuit breaker rated for 15 amps should be
used and clearly marked as the disconnecting device for the
analyzer.
Apply 20 in-lbs of torque on each bolt to ensure the door is closed
properly to maintain required ingress protection.
