Installing Terminal Guard
Terminal guards are shipped with each ring-lug type main and VT terminal block.
These guards must be installed after the terminal block is wired, but before the
Sepam™ Series 80 and equipment wired to the module are energized. (See
preceding DANGER notice.) These terminal guards are designed to prevent
accidental contact with terminals once they are energized.
To install the terminal guards, follow these steps while referring to the illustrations
below:
1 Slightly loosen the two module mounting screws on the ends of one of the blocks.
2 Place the T-slot in the terminal guard over one of the mounting screws and pull it
toward the center of the module until the mounting screw is in the narrow portion
of the T-slot. Tighten the mounting screw.
3 Gently flex the terminal guard as shown and slide the open slot on the terminal
guard under the head of the mounting screw so the screw secures it in place.
Release the terminal guard so it lies flat over the terminals. Tighten the mounting
screw.
Repeat steps 1 and 2 to install the other terminal guard.
The terminal guards should now be firmly in place, preventing accidental contact with
the terminals they cover.
