Pin-to-pin connections between an MFA150 controller card and a BIP
At the MFA150
terminal block TB2:
pin 1 for the black wire,
pins 2 and 4 for the red wire,
no connection (NC) for the white and the
green wires
2 While holding the cable P0940531, align the Berg connector on the cable
with the connector on the BIP. The connectors fit only one way.
3 Press the connectors together firmly but gently until the tab on the side
engages. See the J2 inset in the figure "Cable connection points of the
alarm cable at the BIP and an MFA150" (page 385).
4 Route the cable from the BIP up to the controller of feed A at the MFA150.
Loosely fasten tie-wraps to secure the cable assembly along the path.
5 Determine the distance between TB2 for feed A and TB2 for feed B in the
same controller. Cut 2 wires of 22 AWG (0.326 mm
chaining between the TB2s. See the wiring of the terminal blocks in the
figure "Cable connection points of the alarm cable at the BIP and an
MFA150" (page 385).
6 Prepare the ends of the black and the red wires in the cable assembly and
the 2 daisy-chain wires for insertion into TB2 according to Astec's
document 167-9021-133 Advanced Power Systems MFA150 Modular
Front Access Power System Detailed Installation Guidelines and
Procedures Manual . For example, twist the wire strands of both wires
together or solder them. Ensure that the resulting connections can each
fit the TB2 receptacles.
7 Cut the ends of the green and white wires in the cable assembly and cover
the ends with electrical tape to safely insulate each one from contact.
8 Pass the cluster of wires into the controller up to the controller card for
power feed A. To identify the point of access, refer to Astec's installation
document.
9 Connect the wires of the cable assembly to the TB2 terminal blocks of the
controller cards for power feeds A and B as shown in the figure "Cable
connection points of the alarm cable at the BIP and an MFA150"
(page 385).
