INSTALLATION GUIDELINES AND SAFETY INSTRUCTIONS
This product is intended to be installed as part of a permanently grounded electrical system
as shown in the system con guration sections of this manual with the following important
restrictions:
The negative battery conductor should be bonded to the grounding system at only one point in
the system. If a GFP is present, the battery negative and ground are not bonded.
With the exception of certain telcom applications, the MX60 should never be positive grounded
(see page 61, Applications Notes).
The equipment ground on the MX60 is marked with this symbol:
If damaged or malfunctioning, the MX60 should only be disassembled and repaired by a
quali ed service center. Please contact your renewable energy dealer/installer for assistance.
Incorrect reassembly risks malfunction, electric shock or  re.
The MX60 is designed for indoor installation or installation inside a weatherproof enclosure. It must
not be exposed to rain and should be installed out of direct sunlight.
For routine, user-approved maintenance:
Disconnect all circuit breakers and related electrical connections before doing any cleaning
or adjustments.
Solar modules may produce hazardous voltages when exposed to light; unless
servicing them at night, cover the modules with opaque material before servicing any
connected equipment.
Standards and Requirements
All installations must comply with national (NEC) and local electrical codes; professional installation
is recommended.
DC and Battery-Related Installation Requirements:
• All DC cables must meet NEC standards.
• Shut o all DC breakers before connecting any wiring.
• Torque the four-position terminal block and ground terminals to 30 inch pounds/4Nm.
All wiring must be rated at 75° C or higher.
Use up to 2 AWG to reduce losses and ensure high performance of MX60 (smaller cables can
reduce performance and possibly damage the unit).
Keep cables together (e.g., using a tie-wrap) as much as possible.
Ensure both cables pass through the same knockout and conduit  ttings to allow the inductive
currents to cancel.
DC battery over-current protection must be provided as part of the installation. OutBack o ers
both breakers and fuses for over-current protection.
