PLEASE READ

These instructions are provided so that an OEM can officially convert a

W-VACiMB Mining Breaker to an approved secondary variation. This

variation is required for some OEM’s for them to be in compliance with

end customer needs. The OEM is authorized to do the conversion per

this process and to still have the proper warranty protection.

This procedure is intended to show the necessary steps to remove the

standard secondary connector and replace it with a Push-On type

terminal block that contains the following connections (Refer to Figure

29):

oSpring Charging Circuit

Uses secondary connector pins 25 & 35.

o(1) Shunt Open Circuit (Trip Coil)

Uses secondary connector pins 31& 30.

o(1) Shunt Close Circuit

Uses secondary connector pins 4 & 14.

oControl Under Voltage Release (UVR) Circuit

Uses secondary connector pins 2 & 44.

This requires the UVR option to be installed.

o(2) Normally Open Relays

Relays are open when breaker is open.

1st Relay uses secondary connector pins 7 & 17.

2nd Relay uses secondary connector pins 9 & 19.

o(1) Normally Closed Relay

Relay is closed when breaker is open.

Uses secondary connector pins 23 & 33.

Due to jumping connections in this procedure, the three relays will

have the same voltage/supply as the charge motor. Similarly, the UVR,

Close Coil, Charging Motor, and Trip Coil will share a common return

(See Appendix A). You may choose to not install the jumpers for more

circuit flexibility.

Use appendices A through F for additional information.

TOOLS REQUIRED

Narrow & Thin Flathead Screwdriver

oTo be used on DIN-Rail Mountable Terminal Blocks

Male Pin Remover

8 mm Wrench

10 mm Wrench

Wire Strippers

Step 3:

Using the male pin remover, take out each pin. This can be

accomplished by pressing the male pin remover into a pin slot and

pushing hard to unseat the pin. Once the pin has been unseated,

push from the opposite side of the secondary connector to pull the

pin out of its slot. Repeat for ALL pins (more figures on next page).
