Check aluminum saw terminal box references.
Aluminum Saw Terminal Box
SEW-EURODRIVE describes foot-mounted B3 motors without gear units from output-shaft end A, and gearmotors from fan-guard end B.
In that document, nameplates do not identify terminal-box position.

Drawing
Hypothetical example: a supplier accepted the complete aluminum-saw arrangement. Two drawings show different viewing ends. Identify each exact component and viewing end. A clarification need not change the arrangement.
Send your annotation back to the original provider and ask what its offer actually means. Do not treat an annotation as an approved change merely because someone marked the drawing.

Order
The customer and responsible provider must accept any complete alternative. Ask for a decision on the whole proposal, rather than selecting items from different offers.
Unclear does not mean faulty. Leave it pending. Record who must reply next. Retain the accepted quotation and its corresponding drawing together, so receiving staff can identify the actual purchase.
