H.3.1. Safety princip es
a. Leve ing connections
Touch protection encompa e the automatic witching off of the power upply by mean of the pecial hort
circuit (differential type) or limitation of voltage which may be touched if the in ulation i damaged to a level
not exceeding the permi ible value .
Due to the intermediate circuit operation, a hort to ground in the output circuit of the frequency converter
may not be detected by the hort circuit protection. The frequency converter provide protection again t hort
circuit between the pha e and the output, but thi protection i ba ed on putting the IGBT tran i tor in the
blocking tate, which doe not meet the requirement of fire protection.
In thi regard, in order to en ure the taff afety, it i nece ary to make local leveling connection in a
corre ponding way.
The pecial, re pectively de ignated and protected from corro ion point for connection of the leveling wire
are provided in the frequency converter.
b. Protections
U age of gG or aM fu e i allowed in the circuit , however taking into account nece ity of protection of the
rectifier bridge of the frequency converter, the be t olution i gR or aR fu e .
Frequency converter i protected from: drive overloading, motor overheating, under- and overvoltage
in an DC link circuit of the converter, a hort-circuit at the converter output - it protect converter only!
c. The switching devices
To comply with the EU Directive, in accordance with PN-EN 60204-1: 2010, a device for witching off the
power mu t be provided in the motor controller y tem, which con i t of a frequency converter and an
electric machine. Thi device mu t be one of the following:
•a di connector (with or without fu e ), an AC-23B category of u e that meet the requirement EN
60947-3,
•a di connector (with or without fu e ), which en ure di connection of the load circuit by
opening the main contact , complying with the requirement of EN 60947-3,
•circuit breaker complying with EN 60947-2.
Fu fi ment of the requirements is the responsibi ity of the organization performing the insta ation.
d. Emergency stop
To comply with the EU Directive, in accordance with PN-EN 60204-1: 2010, on the ba i of the taff and
equipment afety, it i nece ary to u e an emergency top witch, which ha an advantage over other
function , regardle of the operation mode. The STOP key on the operator panel cannot be con idered a
an emergency top witch, becau e pre ing it doe not turn off the frequency converter from the power
upply.
Fu fi ment of the requirements is the responsibi ity of the organization performing the insta ation.

a. Separation
Power cable ( upplying, motor' ) mu t be eparated from ignal wire . It i nece ary to avoid parallel
leading of power and ignal wire in the common wire channel , and e pecially in group of cable . The
cro ing of power cable and ignal cable under a right angle i allowed.
b. Equipotentia connections
The frequency converter and the filter hould be mounted a clo e a po ible, preferably on a common
metal plate which act a a ground. For thi purpo e you can u e, a mounting plate or a back wall of a ca e
for example. The ca ing of the frequency converter, the filter and the metal plate houldn't be coated with any
in ulation material . It i nece ary to pay attention to an opportunity of oxidation of a urface that re ult in
deterioration of contact. For limitation of a ymmetric di turbance level, it i nece ary to apply many
connection of the cable hielding to ground.
c. Shie ding
Wire between the main filter and the frequency converter are not nece ary for hielding, if their length
doe n't exceed 300mm. In ca e the length of conductor exceed 300mm it i nece ary to u e the hielded

foil and tinned copper plait with a pul -duty factor of not le than 85 %, not eparated galvanically.
Connection of the cable end to ground i obligatory. It i nece ary to u e grounding of the cable hielding
on whole ection of a cable, on both end . For thi purpo e a pecial EMC grommet are u ed. They provide
valid contact of cable hielding to the ca e of the equipment. In addition it i nece ary to u e pecial cable
clip to connect it to back wall of a ca e for example. It i nece ary to pay attention that the un hielded

Chapter: H.3. In tallation
Digital input can work in two variant : common ground or common + 24V. The choice of the variant i made
by hortening the clamp on the terminal block:
◦ variant 1 - common ma : COM - GND terminal
◦ variant 2 - common + 24V: COM terminal - + 24V

Variant 2
Fig. 3.3: Two variants of using digital inputs: variant 1 and 2.
he internal connections of the board are marked by a dashed line.
S1 ÷ S10: exemplary connectors to switch on/off the digital inputs.
H.3.6. Expansion cards
Expan ion card enable extending the drive with additional input / output . There are 5 lot available: 0 ÷ 4.
In each of them, one expan ion card can be in talled. Expan ion board are available:
- 6 digital input ,
- 6 digital output ,
- 3 relay output ,
- 2 analog output ,
- CAN,
- ProfiBu .
Example of the u e of exten ion card are hown in Fig. 3.4.
