Common Ground for Dual-Output Switching Power Supply

Hello everyone,

I recently purchased a dual-output switching power supply from a Chinese supplier. It provides -15V and +15V outputs, each with its own separate ground (labeled G1 and G2). My application requires a ±15V supply with a common ground. Is it safe to connect G1 and G2 to create a common ground? Unfortunately, the product came without a manual or diagram, so I'm unable to refer to official documentation for guidance.
