2 Installation and Wiring
2.1 Installation
2.1.1 Ambient temperature
-10℃~40℃, with humidity lower than 90%. If temperature>40℃,
the inverter must be derated by 5% for every addition of 1℃. At an
altitude above 1000m, the inverter must be derated by 3% for every
addition of 500m.
2.1.2 Installation location
The location for installing the inverter should meet the following
requirements:
Free from corrosive, inflammable and explosive gases and
liquids.
Free from dust, floating fibers and metallic particles.
The support is firm without vibration.
Free from direct sunlight.
Free from electromagnetic interference.
2.1.3 Installation space and heat dissipation
The inverter will generate heat during operating. To ensure good
ventilation, the inverter must be installed vertically and sufficient
space be kept around it, as shown below:

SENLAN SB40 INSTALLATION AND WIRING
- 8 -
When two or more inverters are installed in one cabinet, horizontal
arrangement is recommended to minimize the mutual thermal
influence. If vertical arrangement is necessary, a separating board
should be provided between them to prevent the heat of the lower
inverter affecting the upper one.
If the cabinet is equipped with exhaust fans at the top, the air flow
of the fans must be greater than the total outflow of individual
inverters. For those without exhaust fans, the top of the cabinet
should be left open if practicable; if not practicable, the area of the
air vent(inlet & outlet) at the top and bottom must be greater than
the total area of the up & down surfaces of individual inverters, and
the wind resistance at the air vent should be as small as possible.
If the inverter is installed on the wall of a control room, the room
not be enclosed and should have good ventilation。

Description of main circuit terminals
Symbol Function
R, S, T Power supply terminals. For connecting 3-phase 380V
power.
U, V, W Inverter output terminals. For connecting a 3-phase motor.
P1, P+ Connect a DC reactor
P1, DB Connect an external braking resistor(0.75 ~ 7.5KW)
P+, DB Connect an external braking resistor(11 ~ 15KW)
P+, N Connect a braking unit
PE Inverter ground terminal
Main circuit power supply terminals [R, S, T]
① Connect the input power to these terminals via a circuit breaker.
The rated current of the breaker should be 1.5~2 times of that of
the inverter. There is no need to match the phase when
connecting.
② It is recommended that the input power be fed to the inverter via
an AC contactor to prevent further problems or damage to the
inverter in the event of a failure.
Inverter output terminals [U, V, W]
① Connect a 3-phase motor to these terminals in correct phase order.
If the run command does not match the rotary direction of the
motor, interchange any two of the U, V, W connections(the
counterclockwise rotation is defined as the forward direction
viewing from the load side).
② Do not connect a capacitor or a surge absorber to the output side

SENLAN SB40 INSTALLATION AND WIRING
- 12 -
of the inverter.
③ When the wiring length between the inverter and the motor are
long, the large inter-wire capacitance may result in abnormal
operation or even overcurrent trip. In this case, connect a filter or
a magnetic ring(s) to the output side of the inverter and
moderately decrease the carrier frequency. Refer to the following
table:
Wiring length <50m <100m ≥100m
Carrier frequency ≤9KHz ≤7KHz ≤3KHz
F79 ≤7 ≤5 ≤2
To suppress the interference generated on the inverter output side, it
is recommended to connect a dedicated filter to the output side, or
place the output power cables(U, V, W) into a metal conduit and
separated them with the control cables.
DC reactor terminals [P1, P+]
① These terminals are used to connect a power factor correcting DC
reactor, which should match the inverter capacity.
② These terminals are connected by a shorting-bar when shipped
from the factory, so remove this bar before connecting the DC
reactor.
③ The shorting-bar should not be removed if the DC reactor is not
used.
Caution

SENLAN SB40 INSTALLATION AND WIRING

External braking resistor terminals [P1, DB]/[P+, DB]
① These terminals are used to connect an external braking
resistor(option). See chapter 9 for specifications of the braking
resistor.
② When connecting the external braking resistor, use a twist pair
with its length less that 5 meters.
③ Never short P+ and DB. That will destroy the equipment.
Braking unit terminals [P+, N]
They are used to connect an external braking unit(option). See
Chapter 9 for specifications of the braking unit.
Inverter ground terminal [PE]
① To reduce noise and prevent electric shock and fire, this terminal
must be grounded securely and the grounding resistance should
be less than 10Ω.
②When connecting multiple inverters to the ground simultaneously,
be careful not to make the grounding wires form a closed circuit.
2.2.2 Control circuit terminals

SENLAN SB40 INSTALLATION AND WIRING
- 14 -
Description of control circuit terminals
Relay output terminals [30A, 30B, 30C]
These are programmable output terminals, can withstand
220VAC/1A.
Multi-function output terminals [Y1, Y2, Y3]
These are open collector output terminals, can withstand 24VDC
/50mA.
Multi-function input terminals [X1 ~ X5]
Refer to F69, Chapter 6.
Analog signal terminals [VRF, IRF, FMA, PO]
VRF: analog voltage input (DC 0~5V or 10V, input resistance
10KΩ).
IRF: analog current input(DC 4~20mA, input resistance 240Ω).
FMA: analog output(0~20mA, 0~10V). It can be output current, load
rate or frequency.
PO: pulse output.
Switch SW1 selects the FMA output between analog current and
voltage signal; SW2 selects VRF input between 0~5V and 0~10V;
SW3 selects VPF input between 0~5V and 0~10V.
External command terminals [JOG, FWD, REV]
JOG: when the inverter is in stop mode, short JOG and CM, then
short FWD(REV) and CM, the inverter will jog
forward(reverse).
FWD: it is valid when F02=1 or 2. Short FWD and CM, inverter will

SENLAN SB40 INSTALLATION AND WIRING
- 15 -
run forward. But if the operation is controlled by the keypad
panel, FWD is just for reverting the inverter direction, that is,
if short FWD and CM, inverter will run reverse, otherwise
forward.
REV: it is valid when F02=1 or 2. Short REV and CM, inverter will
run reverse; short REV, FWD and CM simultaneously, inverter
will stop.
External alarm terminal [THR] and reset terminal [RESET]
THR: open THR-CM, an external alarm signal(oLE) will be
generated and the inverter will immediately shut off the
output.
RESET: shorting RESET and CM will reset the inverter.
External power supply terminals [5V, GND, CM]
5V: control power supply, 5mA
GND: control power supply ground
CM: common terminal
FMA output selector [SW1] and VRF input selector [SW2]
SW1 selects the FMA output signal between analog voltage and
analog current. SW2 selects the VRF input signal between 0~10V and
0~5V analog voltage.
Attention:
Analog signals are easily disturbed by external interference. To
suppress the interference, use shielded cables as the control circuit
wires and firmly connect the shield cables to the common terminal or

SENLAN SB40 INSTALLATION AND WIRING

ground. Separate the control circuit wires from the main circuit wires,
power supply cables and other power lines, and run them across
instead of in parallel.
