UPStealth 2 PIM
The PIM is the device that routes all the power in the system. It takes AC Power from the Utility and re-routes it
through the AUTO BYPASS RELAY and 15Amp breaker (UPS TEST SWITCH) to the UPStealth UPS 2 1000W. The PIM di-
rectly, without breaker, routes AC to the Battery Panel/Battery Module (BATTERY AC OUT). The UPStealth 2 UPS 1000W
returns AC Power back to the PIM (FROM UPS AC OUT) and routes this through a 20Amp circuit breaker and AUTO
BYPASS RELAY to the cabinet load. Terminal blocks for INPUT (from Utility) and OUTPUT (To Cabinet) are isolated via
conduit input hole and cover. The terminal blocks can accept 10-12 AWG wire using a ring terminal or spade terminal.
The UPS TEST switch on the PIM can be utilized to test the UPStealth 2 UPS 1000W which will go into backup mode by
turning the switch from ON (UPS Mode) to OFF (TEST Mode). Because Utility power goes directly to the Batteries (TO
BATTERY AC IN) the UPS TEST switch should not be used for run-time testing. The UPS TEST OUTPUT can be used at
any time to monitor AC Voltage coming from the UPStealth 2 UPS 1000W.
The BYPASS light will go ON anytime there is no UPStealth 2 UPS 1000W in the system (unplugged, damaged, etc.) The
Auto BYPASS relay will route the incoming UTILITY INPUT directly to the CABINET LOAD output.
