STEP 4 - MOUNT THE REMOTE KEYPAD & CONNECT TO THE VFD
CAUTION: It is vitally important that the remote keypad is ALWAYS mounted outside the blade
radius of the fan. This is especially important for the daisy chaining configuration (see page 25). The
daisy chaining process requires access to the keypad while the fan is in motion.
1)
Once a desired location is found, affix
the remote keypad to the wall using
the mounting pads attached to the
keypad enclosure.
2) Run the Cat 6 cable up to the
fan-mounted VFD via the shortest
possible path. If possible, avoid
lighting and other noise-producing
electrical equipment. Running the
cable inside conduit is optional.
3)
Pass the Cat 6 cable through the strain
relief and then into the bottom of the
drive. Connect to the cable coupler
and secure to the inside of the drive as
shown in Image 19.
DO NOT
connect the cable directly to the receptacle on the face of the VFD. Be
sure to tighten the strain relief on the bottom of the VFD.
4)
Replace the cover of the VFD and screw down securely.
STEP 5 - CONNECT THE VFD TO A FIRE SUPPRESSION SYSTEM
(OPTIONAL)
WARNING: There should be no voltage on the fire suppression system cable. Placing voltage
on the VFD terminal block will destroy the unit and void all manufacturers’ warranties.
CAUTION: DO NOT connect Patterson High-5 fans to the fans of another company for purposes
of fire suppression. A separate line must be run for Patterson fans ONLY.
CAUTION: If the drive will not be connected to any fire suppression system, the factory installed
jumper across 9 & 15 MUST remain in place.
1)
Remove the factory installed jumper between terminals 9 and 15. The terminal block is located at the
bottom of the ACS355. For more information, refer to Image 18 on page 18.
2)
Connect the fire suppression system wires to terminals 9 and 15. Again, the fire system cable will
leave the drive enclosure out of one of the holes on the bottom, using a strain relief
(not provided)
.
3)
Drive is now wired to shut down upon activation of any fire suppression signal.
