WARNING
CAUTION
5. The system MUST be disconnected
from the main power supply before
attempting any operation or main-
tenance on the electrical or mechanical part of
the system. Failure to disconnect electrical power
before attempting any operation or maintenance
can result in electrical shock, burns or death.
6. When in operation, the motor and
pump could start unexpectedly and
cause serious injury.
7. Even when the motor is stopped,
dangerous voltage is present at the
Power Circuit terminals U1, V1, W1
and U2, V2, W2 and, depending on the frame size,
UDC+ and UDC-, or BRK+ and BRK-.
8. WARNING! Dangerous voltage is
present when input power is con-
nected. After disconnecting the sup-
ply, wait at least 5 minutes (to let the intermediate
circuit capacitors discharge) before removing the
cover.
9. WARNING! Even when power is
removed from the input terminals of
the SPD Plus, there may be danger-
ous voltage (from external sources) on the power
disconnect or terminals of the relay outputs R01…R03.
10. WARNING! When the control termi-
nals of two or more drive units are
connected in parallel, the auxiliary
voltage for these control connections must be
taken from a single source which can either be
one of the units or an external supply.
11. WARNING! The SPD Plus is not a
field repairable unit. Never attempt to
repair a malfunctioning unit; contact
the factory or your local Authorized Service Center
for replacement.
12. WARNING! The SPD Plus will start up
automatically after an input voltage
interruption if the external run com-
mand is on.
1 3 . WARNING! The heat sink may reach a high
temperature, in excess of 200º F. Severe
burns are possible.
14. WARNING! If the drive will be used
in a floating network, remove screws
at EM1 and EM3 (Frame size R4) or F1
and F2 (Frame size R5 or R6).
NOTE! For more technical information, contact the
factory or your local SPD Plus representative.
15. WARNING! Always consult your lo-
cal, state, municipal or NEC codes for
proper wiring, electrical installation of
inverter drives and AC motors.
