9.3

Requirements

DANGER
Risk of fatal injury from electric shock!
Even if the LED inside the control module is not illu-
minated, voltage may be present!
Electric shock can result in life-threatening injuries
due to safety equipment not fitted (e.g control mod-
ule cover)!
▪ Always switch off the power supply to the pump and, if necessary,
the SSM (FAULT) and SBM (RUN)!
▪ Never operate the pump without a closed module cover!
▪ All openings on the module have to be closed again to ensure en-
closure Type 2.
NOTICE
Always observe nationally applicable guidelines,
standards and regulations and specifications from lo-
cal energy supply companies!
Installation and operating instructions Wilo-Stratos MAXO /-D/-Z
CAUTION
Material damage!
• Incorrect connection of the pump results in damage to the
electronics.
• Suitable mains fuse is required to protect the motor per local
electrical codes.
▪ Refer to current type and voltage on the rating plate.
▪ Use [ 60/75]°C (149/175 °F) copper conductors only.
▪ Minimum fusing: 16 A, slow-blow or circuit breaker with C charac-
teristics.
▪ Suitable for use on a circuit capable of delivering not more than 5kA
rms symmetrical Amperes, 230-240 Volts maximum when pro-
tected by class RK5 fuses.
▪ Internal motor overload protection is provided by overcurrent pro-
tection within the module and PTC within the motor.
▪ Connect and secure both motors individually if using twin-head
pumps.
▪ Only connect to 230 V TN or TT low-voltage networks.
▪ Never connect to 230 V IT low voltage networks (230 V "Isolé Terre"
low voltage network).
▪ Pulse of the power supply (e.g. phase angle control) is not permit-
ted! Deactivate any pulse.
▪ Check pump switching via triacs/semiconductor relays in individual
cases.
▪ For deactivation with on-site power relay: Rated current ≥ 10 A,
rated voltage 250 V AC
