O&M Manual for
Non-Automatic Transfer
Switches (30 – 1200 Amperes)
3.5 Options
Switch options, which are not part of the logic scheme,
are available to meet a variety of other application require-
ments. Options are numbered with an associated descrip-
tion. More detailed selections that must be made within a
specific option are lettered. For available options associated
with the logic scheme, refer to the specific logic document
associated with the type of logic selected.
16. Power Switch with Integral Overcurrent Protection
Use of this option can, in many cases, eliminate the need for
separate upstream overcurrent/short circuit protection, thus
enabling code requirements to be met with a device that
takes up less space and requires less wiring.
B. Both Normal and Emergency Sides
E. Emergency Side Only
N. Normal Side Only
18. IQ Metering
I. IQ Generator — Normal Only
J. IQ Generator — Emergency Only
K. IQ Generator — Both N&E (Selectable)
O. IQ Analyzer — Normal Only
P. IQ Analyzer — Emergency Only
Q. IQ Analyzer — Both N&E (Selectable)
R. DP-4000
E
— Normal Only
S. DP-4000 — Emergency Only
T. DP-4000 — Both N&E (Selectable)
20A. Rear Bus Connections
Front connected solderless lugs are furnished as standard
on all enclosed and open units. Rear bus connections are
only available on open units.

21A. Non-Standard Terminals
(Refer to the Cutler-Hammer business.)
24. Battery Charger
The trickle charge dc output is 12 or 24 volts. Units are sup-
plied in a separate wall mounted enclosure and have an
automatic high-low charge rate.
C. 12 volts
D. 24 volts
When supplied, the battery charger is provided in a separate
wall mounted enclosure (Figure 11). Separate instructions
and wiring information are provided with the charger for
installation purposes.
A separate 120 Vac control power supply is required for
the battery charger input. No connections between the
transfer switch and battery charger should be made.
32. Delayed Transition Transfer Modes for Open Transition
Transfer Switches
Provides delayed transition transfer modes for an open
transition transfer switch. Often used in systems with induc-
tive loads, a delayed transition transfer switch may prevent
or reduce inrush currents due to out-of-phase switching of
inductive loads.
32A. Time Delay Neutral
Provides a time delay in the neutral position during
the transfer and re-transfer operations during which
both Source 1 and Source 2 are disconnected from the
load circuit.
The time delay is programmable and the same for both
transfer and re-transfer operations. Adjustable 3 – 60 seconds.
34. Extender Cable
An extender cable provides a means for extending the
distance between the power switching panel and the logic
panel. This allows for remote mounting of the logic panel.
A. 48 inches (1219.2 mm)
C. 96 inches (2438.4 mm)
E. 144 inches (3657.6 mm)
37. Service Entrance
A. Provides transfer switch as suitable for service equip-
ment rating. A key operated selector switch permits
external, power operated service disconnection with
external pilot light for disconnect indication, also
includes Option 16.
B. Same as A except includes ground fault protection.
41. Space Heater with Thermostat
A. 100 watts
42. Seismic Withstand Capability
Provides transfer switch with seismic capability exceeding
the worst case Zone 4 required levels per both the Uniform
Building Code and the California Building Code.
