Note 1. When ordering, add the rated coil voltage to the model number. Example: G5NB-1A DC5 ~L-_[Rated][coil][voltage] However, the notation of the coil voltage on the product case as well as on the packing will be marked as TLIVDC. Note 2. When ordering tape packing, add "-SP" to the model number. Be sure since "-SP" is not part of the relay model number, it is not marked on the relay case. 1 **==> picture [514 x 131] intentionally omitted <==** **----- Start of picture text -----**
