4.
Crimp the other end of the cable using cord end terminal 14170096 (brown wire) and OT
terminal 14170014 (blue wire), route the cable out of the cabinet top to the PDC through
the strong-current cable trough. Connect the brown wire to the 10 A circuit breaker or
lighting circuit breaker reserved in the PDC, and connect the blue wire to the N busbar in
the PDC.
5.
Crimp the PE cable of the dehumidifier power cable using the OT terminal (M6)
delivered with the dehumidifier, and connect the crimped terminal to a nearby ground
point in the IT cabinet.
Step 7
