WARNING:
• High voltage is present inside the system controller. Use caution when
operating or handling this equipment. Implement lockout/tagout (LOTO)
before servicing any electrical components (see Appendix A). The main
circuit breaker must always be OPEN, or the power plug
DISCONNECTED, prior to performing any service/repair to electrical
systems.
• The system controller contains no user-serviceable parts.
• The system controller includes a tamper indicator. Opening the system
controller enclosure will void the warranty.
