Drive Maintenance
Apply Power
Application of power should only be performed by an experienced user after
the drive is configured and has been through the startup procedure. Before
applying power, it is recommended to review the precautions, warnings, and
other advisory statements in
Prepare for Installation on page 17
.
1. Attach all cables to their respective receptacles. See
Receptacle Connections on page 47
for more
information
.
ATTENTION:
Do not cycle 400/480V AC power more frequently than one
cycle every 1 minute - failure to comply will result in serious equipment
damage.
ATTENTION:
To avoid electrical shock, open the appropriate upstream
protection (disconnect switch or branch circuit protection) before connecting
and disconnecting cables.To avoid an electric shock hazard, verify that the
voltage on the bus capacitors has entirely discharged before servicing.
IMPORTANT
Many of the receptacles could appear to be interchangeable because they
have the same mounting hole pattern. Verify your pin out and connectors
before attaching to the drive. Review the electrical schematics and
receptacle abbreviations.
The receptacle groups that follow have similar mounting hole patterns but,
they are not interchangeable:
• Encoder CFBM and Power Receptacle CPBM for < 14 amps
• M23 Encoders: ENC0, HIPSC, SSIL, DENC0, DENC1, and SSISC
• Power Receptacles: L123, T123, DBR, and EMB1
• Control Power Receptacles: CP, CPBR, and EMB2
• Safety Receptacles: S0 and S1
• Control Receptacles: P0, P1, and DBRT
IMPORTANT
The drive requires a solidly grounded delta-wye power source (for example,
480/277V AC or 400/230V AC, 3-phase power source). If applied to a
grounded or ungrounded 400/480V AC delta power source, abnormal
ground currents will be detected and cause the EMI filter to be damaged.
