Introduction, Safety & Storage
GE transfer switches are used to provide a continuous
source of power for mission, process and healthcare
critical loads by automatically transferring from a pre-
ferred source of power Source 1 (or Normal Source) to a
non-preferred alternate Source 2 (or Emergency) power
source (typically a generator) in the event that Source 1
operational parameters fall outside preset limits.
Voltage and current sensing and system controls are
performed via a state-of-the-art microcontroller located
on the cabinet door. It is designed to give highly accurate
control of the transfer switch system.
All GE transfer switches are designed for use on emergency
or standby systems and are rated for total system or motor
loads. Transfer switches are UL listed under Standard
1008 and CSA certified under Standard C22.2 No. 178.
The safe operation of your switch at all times is GE’s focus.
It must be recognized that hazardous voltages and
currents can exist during normal operation and any
maintenance on the transfer switch must be performed
utilizing appropriate safety measures. Installation,
adjustment, maintenance or removal of the switch must
only be carried out by qualified personnel with all power
to the switch turned off. It is recommended that only
qualified electricians be allowed to install or provide
maintenance on the switch.
Regarding the switch itself, proper storage, installation,
operation and maintenance will help increase its operational
life. Upon initial receipt of the transfer switch, inspect for
any damage. This includes damage to the enclosure, power
panel, control panel and wiring harnesses. If any damage
is found or suspected, file a claim as soon as possible
with the carrier and notify the nearest GE representative,
or call
1 + 800 637-1738 or 1 + 773 299-6600.
Prior to installation store the transfer switch in a clean dry
location, protected from dirt and water. Provide ample air
circulation and heat, if necessary, to prevent condensation.
See Table 1 for recommended storage and ambient
operating temperatures.
CAUTION
Due to hazardous voltages and currents, GE recommends
that a GE Certified technician or a qualified electrician
perform the installation and maintenance of the switch.

DANGER
HAZARDOUS VOLTAGE CAN CAUSE
SEVERE INJURY OR DEATH
Turn OFF all power before installation, adjustment or
removal of transfer switch or any of its components.
!
NOTE
A protective device such as a molded case circuit breaker or
fused disconnect switch MUST be installed on both sources of
incoming power for circuit protection and as a disconnect device.
All references made within this manual about the terms
“Source 1”, “S1” or “Preferred Source” relate to a “Normal”
power source (typically from a utility source). References made to
“Source 2”, “S2”, “Non-preferred Source” or “Alternate Source”
relate to an Emergency Source (many times a generator).
