The door to the ballast enclosure must be opened to gain access to external
alarm and remote start/stop contacts. As well, the blower and blower housing
must be removed for cable entry. See Figure 1G & 1H.
Step 1: Loosen screw that secures door – no need to remove.
Step 2: Unplug blower from circuit board – connector J6.
Step 3: Open blower housing panel and remove screw that secures it.
Step 4: Gently pull out blower housing and blower allowing connector and wire to
follow.
Step 5: Remove knockout & install conduit / external wiring up to circuit board
and terminate. Wiring may be secured internally to standoffs but allow enough
slack to allow front panel to open.
Step 6: Test opening of front panel to ensure newly installed wires do not restrict
movement.
Step 7: Replace blower and blower housing and allow connector & wire back to
the circuit board. Secure with screw. Ensure wires do not obstruct blower.
Step 8: Plug in blower connector to J6.
Step 9: Close ballast enclosure door and secure with screw.
