Before Servicing

Servicing the electrical control box exposes you to
high voltage. To avoid electric shock;
• Turn off power at the main circuit breaker before
opening the enclosure.
• All electrical wiring must be done by a qualified
electrician and comply with all local codes and
regulations.
• Do not substitute or modify system components
as this may impair intrinsic safety.
NOTICE
To avoid damaging the circuit boards when
servicing the control box, wear Part No. 112190
grounding strap on your wrist and ground
appropriately.
To avoid electrical component damage, remove all
system power before plugging any connectors.
