1. Introduction

The Go Power!™ Transfer Switch 50 (TS-50) provide automatic power switching
between two or three separate 120/240 volt AC input sources, including power
cords, onboard generators, onboard inverters, or all three. The ATS will sense the
presence of available power supplies and automatically select the proper one.

The TS-50 can be installed at the electrical entry of the RV on the line side of the
main distribution panel, or it can be installed on the load side of the panel between
the main panel and a sub panel, allowing switching for either the entire electrical
load or only designated circuits switch ground bar. A direct access hole to the
ground bar is provided through the enclosure for convenience.

Determine proper connections of wire conductors to electrical terminals. On 120
VAC wiring the ground wire is bare or green, the neutral wire is white, and the hot
wire is black. On 240 VAC

READ AND FOLLOW ALL SAFETY INSTRUCTIONS!

2.1 Disconnect Power

Make sure the generator is off, the external power cord is unplugged, and the
inverter, if any, is shut off.

2.2 Mounting Location

The TS-50 mounting location may be on any interior surface where the unit will be
out of direct weather. The chosen location must be accessible after installation is
complete to facilitate future servicing. If possible, mount the TS-50 near the power
cord entry or the location of the generator output. Typical locations include under
counter cabinets, below closet compartments, inside the bed pedestal or cabinets,
overhead cabinets, under-floor storage compartments accessed from the vehicle
exterior, etc.

2.3 Electrical Preparation

Use knockouts 12, 5, and 6 when installing the TS-50. Do not use knockouts 3, 4,
7, and 8 when preparing the TS-50 for installation.

2.4 Mounting

Mount the TS-50 with screws through holes provided in bottom corners of the can.
The unit should be screwed to a solid surface firmly enough to hold its weight
during vehicle operation.

2.5 Electrical Connections

A. Attach an 8 gauge chassis ground wire to the transfer switch ground bar.

A direct access hole to the ground bar is provided through the enclosure for
convenience.

B. Determine proper connections of wire conductors to electrical terminals.
On 120 VAC wiring the ground wire is bare or green, the neutral wire is
white, and the hot wire is black. On 240 VAC wiring there are two hot wires;
one is black, and the other is red.

C. Strip the outer jacket from all of the incoming cables. Strip insulation from
all ends of the copper conductors. Insert cables through clamps in openings.
Do not tighten cable clamps at this time.

D. Route internal ground wires around lower area of enclosure and secure
to ground wires away from electrical contacts on components to avoid the
possibility of electrical short-circuit.

E. Connect the ground wires to the ground bar. Tighten terminals to a
minimum of 20 inch-pounds.

F. Connect the neutral (white) wire connections.
G. Connect the hot wire(s). If there is a black wire and a red wire (for 240

VAC), it does not matter which is hot 1 and which is hot 2.
H. In some applications it may be desirable to feed a 120 volt supply, such

as an inverter, into both hot legs of a transfer switch, so that the 120 volt
supply can operate the entire RV load. Although discretion is advised in
designing this into the system, it is acceptable, as long as the connection to
both hot legs is accomplished on the input side of the transfer switch. To do
this, connect the hot from the 120-volt supply, such as an inverter, to hot 1,
and then attach a jumper wire of the same gauge from hot 1 to hot 2.
Consideration should be given to the following:

• The entire load must be 120 volt; you cannot operate a 240 volt load from
a 120 volt supply.

• There may be a load which would be undesirable to run from this
particular 120 volt supply; that load should be isolated when the 120 volt
supply is operating. The TS-50 is sometimes used as a ‘lock-out’ switch to
prevent specific loads from being operated from designated supplies.
Example: preventing a battery charger or air conditioner from running from
an inverter, yet operating from generator or powercord.

I. Tighten cable clamps on switch enclosure.
J. Attach lid. The lid is designed to snap on and should not open without

deliberate effort.

2.5.1 Installation Between Powercord and Generator
(Configuration A)

The TS-50 is designed with an easy-to wire bridge. Refer to Diagram 1 for wiring
lug designations.

1. Connect the powercord neutral to the powercord lug labeled NEUTRAL
WHT.
