求翻译：注意应轻拿轻放，防止变形，损坏隔爆面，可看到内部的接线端子，电加热器的接线端子为两组分别为U1、V1、W1；接线方式为Δ（以下简称U、V、W）是什么意思？

Note should be light to light, to prevent deformation, damage, explosion-proof surface, can be seen within the terminal, the terminal of the electric heater for the two groups, respectively, u1, v1, w1; wiring for Δ (hereinafter referred to as u, v. , w)

Note that you should handle with care, and prevent deformation, damage from explosions, you can view the inside of the terminal, electric heaters for the terminals for both U V 1, 1, 1; W wired (hereinafter referred as Δ U , V W),

The attention should handle with care, prevents the distortion, the damage flame-proof surface, may see internal binding clamp, the electric heater binding clamp is two groups respectively is U1, V1, W1; The wiring way (hereafter refers to as U as DELTA, V, W)

Note You should handle with care to prevent deformation, damage the flameproof surface, you can see the internal terminals, terminals of electric heater into two groups namely, U1, V1, W1; wiring for δ (hereinafter referred to as u, v, w)
