Quick Start Guide • Strictly adhere to all ANSI/NFPA 70 (North America) and local electrical codes.
• Improper installation may cause damage not covered by the warranty.

• Do not install TS4s that are physically damaged or have damaged or substandard wiring or connectors. TS4 Mounting Options For frameless modules, use M8 bolts torqued to 10.2 Nm.
• Do not connect or disconnect TS4s under load.

• Caution: Risk of fire and shock hazard. Device(s) must be protected at system level (PV string) with PV fuse rated maximum 20 A, minimum voltage
rating based on system voltage, 600 VDC, 1000 VDC, or 1500VDC.
• TS4-A-F/2F PV array (DC) conductors are 12 AWG.
• Normal operating temperature range is -30 °C to 70 °C.
• TS4-A-F/2Fs are compatible with the grid support function described in UL 1741 Tables SA9.1 and SA10.1: response to low- and high-voltage ride-
through (L/HVRT) and low- and high-frequency ride-through (L/HFRT) requirements.
• Connectors from different manufacturers cannot be mated with each other.
• Modules must not be installed in readily accessible locations (Canada only).
