Neron models of elliptic curves with level N structure?

In the Deligne-Rapoport paper entitled "Les schemas de modules de courbes elliptiques" the following is written (I translated in english):

Let $E$ be an elliptic curve with $\Gamma(N)$-level structure defined over $\mathbb{C}((T))$. Let $E'$ be the minimal model of $E$ over $\mathbb{C}[[T]]$. It may happen that $E'$ has bad reduction (i.e. when one reduces modulo $T$). So let $A$ be the neron model of $E'$ over the d.v.r. $\mathbb{C}[[T]]$. Then it seems that the special fiber of $A$ (i.e. when $T=0$) is always isomorphic to $\mathbb{C}^{\times}\times\mathbb{Z}/kN$ for some suitable integer $k$.

Q: How come this $N$ shows up in the special fiber of $A$ ?

This is a little bit strange since in the definition of a Neron model no such $N$ appears.

I wonder if you need to assume $N \ge 3$ to exclude $I_0^*$-reduction. In that case the component group is $\mathbb Z/2 \times \mathbb Z/2$. Or do you assume multiplicative Reduction right away? In that case characteristic zero is not needed. In charakteristic $p$, you have to be careful because additive reduction gives you a lot of $p$-Torsion. –  Holger Partsch Jan 6 '11 at 13:52
