The transfer Switch is designed for a maximum voltage of 120/240V, Single Phase 3 wire with neutral or Three Phase 4 wire with neutral. Verify the line
voltage and amperage of the transfer switch matches the site requirements. Note: The transfer switch can be configured for operation on 220V or 208V
sources by way of configuration jumper. Refer to section H of this guide for further information.

WARNING: Do not install the transfer switch if either voltage or amperage does not match. Failure to follow these instructions can result in

death, serious injury, or equipment damage.

D. Installation Requirements

Before installing the transfer switch, review the following requirements:

 Installation Codes/Permits and ATS Sizing: Suitable permits are typically required by local jurisdictions having authority prior to installing

standby generator sets and automatic transfer switches. Per NEC Article 702, Automatic transfer switches shall be sized for either a) entire load
whole house, load calculation per NEC 220, or b) Pre-selected “EM” panel(s) of load being served or optional standby panel and transfer switch,
or c) automatic load shedding feature to reduce total load imposed on the generator, not to exceed the capacity of the generator. The TS 910/920
transfer switches have automatic load shedding capabilities built-in when load shedding control contact is connected. Refer to Load Shedding
section of this guide for further details.

 Installation Location: The standard TS 910/920 transfer switch is designed for indoor wall mounting. For applications requiring outdoor wall

mounting, a NEMA 3R door kit is optionally available. The transfer switch must be installed in an environment where the temperature range is
within +5° to +122° Fahrenheit (-15° to +50° Celsius) and humidity range not exceeding 5%-95% non-condensing.

 Power Cabling: All power cabling entering/exiting the enclosure must be installed in suitably sized conduit per NEC requirements. Ampacity, type

and voltage rating of current carrying conductors must also comply with NEC requirements and local jurisdictions having authority.

 Control Wiring: All control wiring for engine start, load shed, alarm and remote test must be installed in separate conduits from all power cabling

and must utilize suitably sized conduits per NEC requirements. All control wiring shall be sized for minimum #14 AWG. Control wiring type and
voltage rating must also comply with NEC requirements and local jurisdictions having authority.

 Generator Set Automatic Operation: The TS 910/920 transfer switch operates in conjunction with any generator set with remote automatic

starting capabilities utilizing a 2 wire, remote start control contact input. A dry contact is provided for remote generator starting control (contact
closes to start generator and opens to stop generator). Note: For generator sets requiring a 240V starting control circuit a “Universal Generator
Start” (i.e. UGI) kit is optionally available for field install. Refer to Automatic Sequence of Operation section of this guide for further details.

 Upstream Overcurrent Protection (Non-Service Entrance Rated TS 910/920): Non-Service Entrance Rated TS 910/920 transfer switch models

do not contain any integral over current protection and require upstream over current protection devices for both Utility and Generator sources.
The standard TS 910/920 is suitable for control of motors, electric discharge lamps, tungsten filament lamps, and electric heating equipment
where the sum of motor full-load ampere ratings and the ampere ratings of other loads do not exceed the ampere rating of the switch and the
tungsten load does not exceed 30 percent of the switch rating. The Standard TS 910/920 is rated for 100% continuous loading subject to load
content described above and can withstand a maximum short circuit fault current as noted in Table #1 of this document. The standard TS 910/920
transfer switch model without integral over current protection is identified in the product model code.

 Upstream Overcurrent Protection (Service Entrance Rated TS 910/920): Service Entrance rated TS 910/920 transfer switch models contain

integral over current protection for the Utility source as standard. Service Entrance rated TS 910/920 transfer switches do not contain any integral
over current protection for the generator source and requires upstream generator source over current protection. Service Entrance rated TS
910/920 is suitable for control of motors, electric discharge lamps, tungsten filament lamps, and electric heating equipment where the sum of the
motor full-load ampere rating and the ampere rating of the other loads do not exceed the ampere rating of the switch and the tungsten load does
not exceed 30 percent of the switch rating. The Service Entrance rated TS 910/920 is rated for 80% maximum continuous loading subject to load
content described above and can interrupt/withstand a maximum short circuit fault current as noted in Table #1 of this document. Over current
protection provided on the utility source is non-adjustable thermal-magnetic type.
