Conditions of Acceptability:

  1. Total branch output current shall not exceed 200A (ac) Max.
  2. Bare buses and connections are bare, connection shall meet either the minimum spacings specified in Table 26.1 as per UL1741 spacing requirement or Table 16.1 of UL67 or CSA C22.2 No.29 Table 2 whichever is the highest.
  3. All openings must meet the manufacturer’s recommended fitting to meet the enclosure rating.
  4. All listed insulation barriers and shields must be certified to minimum flame rating of V2 as per CSA 0.17(R2018) and/or UL94 unless otherwise stated in the critical component.
  5. This evaluation does not include metering measurements, it is treated as an intent for internal system application only.
  6. It is intended for use with Lunar Model: 10-005025 (a.k.a Lunar Inverter), and other Lunar associated safety approved devices only.
  7. Where applicable for metering device, associated Electromagnetic Immunity tests are to be conducted at end system level.
  8. When the Bridge is not used as a main panel (when the Bridge is not installed at the service entrance), the Neutral-to-Ground bonding wire MUST NOT be installed in the Bridge enclosure. Ensure that Neutral and Ground are properly bonded in the upstream equipment at the service entrance.
  9. When the Bridge is to be used as the main panel, installation shall have Neutral-to-Ground bonding wire in the Bridge.
  10. Conformal coating process as per document numbers 10-003104 and 10-003105 (See Att5 PCB Layouts).
  11. If installed in environments with temperatures below 0°C, the circuit breaker in the panelboard should not be considered reliable for overload protection. Separate overload protection, as mandated by both CEC and NEC, must be implemented in such conditions.
  12. The product’s Power Line Communication (PLC) functionality and usage were not assessed as part of this evaluation. Should such functionality be required for the intended end-use application, a separate and dedicated evaluation shall be conducted.
  13. Please refer to the verification of Conformity Letter 80233547 VOC for additional information on the Power Control System (PCS).
  14. Construction of panel with service entrance rating:
    a. Main breaker shall be installed with accepted UL and/or CSA listed breaker, Square D QOM2200VH or smaller rating.
    b. Line side barrier shall be installed in line side terminal: UL recognized.
    c. Neutral is bonded to grounded by bonding jumper.
    d. The “service disconnection”: label shall apply close to main breaker.
