Installation
Electrical Connections
This product must be grounded. In the event of an
electrical short circuit, grounding reduces the risk of
electric shock by providing an escape wire for the
electric current.
• The control center must be electrically connected
to a true earth ground; the ground in the electrical
system may not be sufficient. Refer to your local
code for the requirements for a "true earth ground"
in your area.
• All wires used for grounding must be 18 AWG
minimum.
• All electrical wiring must be done by a qualified
electrician and comply with all local codes and
regulations.
• For 24 Vdc wiring refer to F
• For 100-240 Vac wiring refer to F
• Incoming power wiring must be guarded from the
enclosure. Use a protective grommet where the
power wiring enters the enclosure to prevent
wear.
NOTICE
If power and grounding connections are not done
properly, the equipment will be damaged and the
warranty voided.
