O&M Manual for 30-1000 Amperes

 Manual Transfer Switch

4.6 Wiring

Power sources, load conductors and control wiring should be con-

nected to locations as indicated in the Customer Wiring diagram 

supplied with the transfer switch equipment. Only applicable if 

these options are added.

Once the transfer switch equipment has been installed and wired, 

perform initial mechanical and electrical procedures as outlined in 

Section 6 to verify that the equipment is installed and operating 

properly.

4.7 Voltage Selection Adjustments - based on 

configuration

Certain devices, such as the Voltage Selection Panel, sensing 

relays and timers, need to be set and/or calibrated prior to placing 

the transfer switch equipment into service. Adjustments for logic 

devices are described in Section 3.5. Voltage selection adjust-

ments are described here

Figure 16.  Line Voltage Plug and Receptacles (Shown with 

Covers Removed) for Horizontal Design.

Vertical Design Voltage Selection

The vertical design transfer switch is furnished with a multi- tap 

Voltage Selection Panel to the right of the power panel. Seven 

front accessible taps from 208 to 600 Vac are provided (Figure 9). 

A small disconnect plug is provided to change from one voltage to 

another.

Horizontal Design Voltage Selection

Horizontal design transfer switches are furnished with an adjust-

able line voltage plug and receptacles below the power panel. To 

change the line voltage, remove the covers and insert the plug in 

the desired receptacle (Figure 17).

    

 

CAUTION

POWER CONDUCTORS AND CONTROL WIRING MAY HAVE VOLT-

AGE PRESENT THAT CAN CAUSE SEVERE PERSONAL INJURY OR 

DEATH. DE-ENERGIZE ALL POWER OR CONTROL CIRCUIT CONDUC-

TORS BEFORE BEGINNING TO PERFORM ANY WIRING ACTIVITY TO 

OR WITHIN THE TRANSFER SWITCH EQUIPMENT

    

 

CAUTION

DO NOT RUN POWER CABLES BEHIND OR TO THE LEFT OF THE 

POWER PANEL. THE CABLES SHOULD BE RUN IN THE GUTTER 

SPACE PROVIDED. RUNNING THE CABLES IN PLACES NOT RECOM-

MENDED COULD INTERFERE WITH THE PROPER OPERATION OF THE 

TRANSFER SWITCH.

    

 

CAUTION

CHECK THE TRANSFER SWITCH EQUIPMENT NAMEPLATE FOR 

RATED VOLTAGE.  IT SHOULD BE THE SAME AS THE NORMAL AND 

EMERGENCY LINE VOLTAGES. OPERATING THE EQUIPMENT ON 

IMPROPER VOLTAGE CAN CAUSE EQUIPMENT DAMAGE.

    

NOTICE

REMEMBER TO RE-ATTACH THE SOLID STEEL POWER PANEL DEAD-

FRONT SHIELD TO THE RATCHET ASSEMBLY ON THE VERTICAL 

DESIGN AFTER COMPLETING ANY OF THE PROCEDURES 

DESCRIBED IN THIS SECTION.

    

 

CAUTION

BE SURE THAT THE CORRECT VOLTAGE IS SELECTED TO MATCH 

THE SYSTEM VOLTAGE. AN IMPROPER SELECTION AND/OR CON-

NECTION COULD RESULT IN EQUIPMENT DAMAGE.
