APC 990-1031, SYPM2KU, SYBT2 installation manual

Input Voltage Selection Switch ’: Set this switch to the appropriate setting, either 200/208 (L1-L2-G) or 220/230/240 (L1-N-G) before powering up the Symmetra RM.

Products rated 200/208 are typically installed in North America (208 V, phase to phase, grounding conductor) and Japan (200V, phase to phase, grounding conductor).

Products rated 2020/230/240 are typically installed in the rest of the world (220 V, 230 V, or 240 V, phase to neutral, protective earth). These products must be hard wired to the input power.

Maintenance Bypass Switch “: When switched to the On position, the maintenance bypass switch bypasses the Symmetra RM, and causes the load equipment to be powered directly from utility power. When it is switched to the Off position, utility power flows into the Symmetra RM, and conditioned power is delivered to the load equipment. Under normal operating conditions, the maintenance bypass switch remains in the Off position.

The load equipment is unprotected when the maintenance bypass switch is in the On position.

Input Wiring Access Panels ”: Provides access to wiring terminal blocks for input wiring. The 200/208 (L1-L2-G) version must be hard wired if the load is greater than 5 kVA. The 220/230/240 (L1-N-G) version must always be hard wired.

Input Power Cord ‹ [on 200/208 (L1-L2-G) versions only]: The 200/208 (L1-L2-G) version can use the line cord to connect to the power source if the load is less than 5 kVA. If the load is greater than 5 kVA, the unit must be hard wired to the power source. The 220/230/240 (L1-N-G) version must always be hard wired.
