The 4010 ships from the factory completely assembled in the back box, or as a
single piece electronics assembly that is shipped separately from the back box,
retainer, and door. The system electronics (SFI/O and power supply) are
mounted to a steel chassis. Refer to the 526-407 label inside the back box for
additional information.
Prior to installation you must remove the chassis containing the 4010 SFI/O and
power supply from the back box. Use the following steps to remove the chassis.
1. Remove the door grounding wire from the back box. Remove the door from
the hinges and set it aside.
2. Remove the metal retainer by gently lifting and pulling the bottom of the
retainer out from the back box. Then, being careful not to drop the retainer,
slide the top of the retainer out from under the lip of the top of the back box.
3. Remove the AC wiring Quick-Disconnect connector from the chassis by
firmly squeezing the release tabs and pulling it free. The Quick-Disconnect
connector is located directly below the chassis. Dress the wires so that they
do not interfere with back box installation.
4. Loosen or remove the four mounting screws holding the chassis to the back
box.
5. Lift the chassis out of the back box and store in a clean, dry, safe area for re-
installation later.
Determine the amount and proper location of conduit/service entrances. Make
all appropriate entrances into back box (see Figure 2-1).
Caution: Power-Limited and Non-Power-Limited wiring must enter
through separate conduit/service entrances. AC power
entrance into back box is recommended at the bottom right
side of the back box.
If a Bus Bar is required to terminate wire shields, see Figure 2-1 for proper
mounting location. Entrances for shielded wire must be located within two
inches of the bus bar. Maximum intrusion into box for conduit is 1/2-inch.
