Data Cabling Preparation
Step 1: Identify the different dimmer output ribbon cable transition cards. An SP48 will
only use a single upper and lower card.
Step 2: Mate the transition cards with the ribbon cable edge connectors as indicated
below. Secure the ribbon cable connectors to the transition cards with wire ties.
The tie wrap binding needs to be on the top for an Upper board and on the
bottom for a Lower board for adequate clearance. Clip wire tie ends for
neatness.
N o t e : There are two different types. An “upper” card and a “lower” card. The transition
card is marked with both the type and which side should be up when installed.
