5. The Fully Extended Limit Switch Cable will ship installed. Ensure the 3-pin Fully
Extended Limit Switch Cable is securely in place between the Fully Extended Limit
Switch and bulkhead connector J7 at the base of the mast.
Connect Power to the Mast System
Power and the handshake lines enter the Universal Control Box through bulkhead connector J1.
The Will-Burt Company supplies a 9-pin Power Cable Connector (Section 1.7.1.10) to connect
to J1. If the EMI filter is required, the connector plugs into the input side of the filter and the
cable supplied with the filter connects from the filter output side to the Control Box J1. The
customer is responsible for integrating 10-gauge (6 mm
2
) power lines (with optional ground) and
any handshake lines into the Power Cable Connector. With cable runs longer than three meters
(ten feet), a lower gauge wire will be needed.
The enable input circuit (hatch switch) on J1 Pins A and B require a closed circuit to enable
mast operation. If no switch is installed to provide a closed circuit, a jumper is required to
connect J1 Pins A and B.
The Will-Burt Company also offers optional Input Power Cable Pigtails (Section 1.7.4.3) which
have a Power Cable Connector with pre-wired flying leads of predetermined lengths to simplify
the wiring process.
The mast does not have a master power switch. If a master power switch is desired, the
customer must provide it with the source power.
An Emergency Stop Switch Kit (P/N: 4792701) (Figure 2-10) is supplied with each mast. This kit
includes a panel mounted push-pull E-Stop switch, and a legend plate. The emergency stop
shall be installed in a position reachable by the operator when operating the mast with the mast
controls. This Emergency Stop Switch kit must be used for CE compliance.
