2. Place a flat blade screwdriver at the edge of the
knockout. Gently tap the screwdriver with a hammer
to carefully remove the conduit plug.
3. To maintain the IP65 moisture protection rating,
select an appropriate water tight conduit connector.
Wiring
See Figure 4 and Table 2 for electrical termination
locations, terminal labels, and wiring information for low-
voltage terminations.
See Figure 5 and Table 3 for electrical termination
locations, terminal labels, and wiring information for high-
voltage terminations.
See Table 8 to Table 12 for the high-voltage relay electrical
ratings.
WARNING
Risk of Electric Shock
Disconnect or isolate all power supplies before mak-
ing electrical connections. More than one disconnec-
tion or isolation may be required to completely de-en-
ergize equipment. Contact with components carrying
hazardous voltage can cause electric shock and may
result in severe personal injury or death.
AVERTISSEMENT
Risque de décharge électrique
Débrancher ou isoler toute alimentation avant de
réaliser un branchement électrique. Plusieurs iso-
lations et débranchements sont peut-être néces-
saires pour-couper entièrement l'alimentation de
l'équipement. Tout contact avec des composants con-
ducteurs de tensions dangereuses risque d'entraîner
une décharge électrique et de provoquer des
blessures graves, voire mortelles.
Important:
• Use copper conductors only. Make all wiring in
accordance with local, national, and regional
regulations.
• Do not exceed the A525 Fermentation Controller
electrical ratings. Exceeding controller electrical
ratings can result in permanent damage to the
controller and void any warranty.
• Run all low-voltage wiring and cables separate
from all high-voltage wiring and route wires for
National Electric Code or local electrical code
requirements. It is best practice to use shielded
cable for low-voltage cables that are exposed to
high electromagnetic or radio frequency noise.
• Electrostatic discharge can damage control
components. Use proper electrostatic discharge
precautions during installation, setup, and
servicing to avoid damaging the controller.
• Do not connect supply power to the controller
before you finish and check all wiring connections.
Short circuits or improperly connected wires can
result in damage to the controller and void any
warranty.
