Installation Instructions
LP250RDB4
The LP150/LP250 is a power-limited power supply and battery charger that will convert 120 VAC / 60Hz input into eld-selectable 12 VDC
or 24 VDC Class 2 rated outputs (one continuous, one switchable). It is intended for use in applications with UL listing requirements (see
specications below for specic listings).

1 Installation Overview
Wiring methods shall be applied in accordance with the National Electric Code/NFPA 70/NFPA 72/ANSI, and with all local codes and
authorities having jurisdiction.
WARNING
To avoid risk of electric shock, turn off AC power before
installing or servicing LP150/LP250 power supply.
1. Mount unit in a protected area per Section 2.
2. Select voltage (12 or 24 VDC) per Section 3.
3. Connect AC power per Section 3.
• Connect the earth ground to the green/yellow cabinet wire and line (L) and neutral (N) to the appropriate terminals on the AC
terminal block.
Measure output voltage before connecting devices to prevent damage.
4. Disconnect AC power and nish all wiring per Sections 4 and 6.
5. Install battery backup (if required) per Sections 2 and 3.
If AC input goes o and battery backup is not being used, all devices connected to the power supply will be unpowered.
6. AC status may be required for Battery Backup systems (Section 3).
7. Secure cover with screws or keylock when complete per Section 7.
8. For maintenance and troubleshooting, see Sections 8 and 9.
