Section 2: Front-mounted connections

CAUTION

WHEN MAKING BOLTED CONNECTIONS TO THE EQUIPMENT OR TO THE ADAPTERS THEMSELVES, ALL WHICH HAVE PRE-TAPPED HOLES, IT IS IMPORTANT NOT TO EXCEED THE RECOMMENDED TORQUE VALUES. IN ADDITION, ANY CONNECTION HARDWARE USED SHOULD BE THE EXACT LENGTH REQUIRED AND NOT EXTEND OUT PAST THE MOUNTING HOLE. FAILURE TO FOLLOW THESE REQUIREMENTS COULD RESULT IN EQUIPMENT DAMAGE AND/OR FAILURE.

Front bus adapter

Proceed with the following five steps:
Step 1: Position the front bus adapters (stack adapters as needed
for higher ratings) on the primary terminal pad as shown. Install the M8 hardware provided into the four mounting holes and hand tighten (Figures 2 and 2a). The number of front connect bars is dependent on the current rating: up to 1600A = 1x, up to 2500A = 2x, 3200A = 3x per flat connection.
Step 2: Position the braces to the bus adapters as shown. Install the M12 hardware provided and hand tighten (Figures 3 – drawout shown). Braces for fixed and drawout configurations installed in the same manner.
Step 3: Using a torque wrench, torque all M8 bolted connections to 177 in-lbs (20 Nm).
Step 4: Using a torque wrench, torque all M12 bolted connections to 780 in-lbs (88 Nm).
Step 5: Refer to Figures 5 and 5a for applicable configuration and dimensions.

IMPORTANT

IT IS RECOMMENDED THAT THE REAR OF THE FRONT CONNECT TERMINALS BE INSULATED FROM ANY GROUNDED METAL TO HELP PREVENT ACCIDENTAL CONTACT.
