Page 11: Safety Instructions: Handling
Important safety instructions 4.4 Safety Instructions: Handling Warning – The 30C3 and 30C Converters weigh approximately 135 pounds. They are designed to be transported and wall-mounted by two people, without the use of lift or power equipment. If lift or power equipment is used to move, or lift the Converter, follow all safety rules. -
Page 12: Ground Fault Detection - Floating Systems
Important safety instructions 4.8 Ground Fault Detection – Floating Systems Floating battery or PV Arrays utilize an onboard “IMI” ground fault detection scheme. This enables the converter to measure the leakage to ground of the DC Power source. If leakage to ground currents are present past the limits set in UL1741 then the unit will fault and prevent operation until the fault is cleared from the DC source. -

Unpacking and Mounting the Converter 6. Unpacking and Mounting the Converter Two-man lift: Observe all safe practices while moving or mounting the Converter. The Converter can be set safely on its back or vertical if properly supported until it is ready to be mounted. Storage before installation: Store the Converter in its original shipping container indoors in a non-condensing environment between the range of -40 °C to 85 °C. -
Page 15: Clearances For Converter Mounting
Unpacking and Mounting the Converter 6.2 Clearances for Converter Mounting: • Minimum bottom clearance requirement: Outdoors or Indoors: 18 inches above. Violation of this clearance will void the warranty. • Minimum front clearance requirement: 36 inches from the front of the Converter must be clear of flammable materials or obstructions. - Page 16 Unpacking and Mounting the Converter Secure the wall mounting bracket to the desired surface using either a metal Uni-strut type railing rated for the Converters weight or a concrete wall. Ensure mounting bracket is level within +/- 5 degree. Figure 3: Door Clearance Guide The PCS installation must allow the front door to swing freely open for service purposes.
