NORDAC SK 200E Manual 2 Assembly and installation 2.1 Installation and assembly NORDAC SK 200E frequency inverters are available in various sizes depending on their output. Connection of the SK 200E to the motor or the wall-mounting unit is made by means of the a suitable size of connection unit SK T14-… The frequency inverter is mounted by means of integrated plug contacts. The devices require adequate ventilation to protect against overheating.
2 Assembly and installation Mounting the adapter unit For the supply of a complete drive unit (gear unit + motor + frequency inverter) the SK 200E frequency inverter and the SK T14-... adapter unit are always completely assembled and tested. The adapter unit can also be ordered separately for subsequent mounting on an existing motor or to replace a different motormounted frequency inverter. NOTE However, the IP66 compliant SK 200E must be installed by NORD, as special measures must be implemented.
NORDAC SK 200E Manual 2.2 Electrical connection WARNING THE DEVICES MUST BE EARTHED. Safe operation of the devices requires that is installed and commissioned by qualified personnel in compliance with the instructions provided in this Manual.

NORDAC SK 200E Manual 3 SK 200E displays and control By combining different modules for display, control and parameterisation, the NORDAC SK 200E can be easily adapted to various requirements. Alphanumeric display and control modules (Illustration below) can be used for simple commissioning. For more complex tasks, connection to a PC system and the use of Nord Con parameterisation software is available. As supplied, without additional options, the diagnostic LEDs are externally visible.
4 Commissioning 4 Commissioning, SK 200E The SK 200E inverter series can be commissioned in various ways: a) For simple applications (e.g conveyor applications) by means of the DIP switches integrated into the SK 200E (inside) and potentiometers (externally accessible). In this configuration the plug-in EEPROM is not required. b) Through adaptation of parameters using software via the ParameterBox (SK CSX-3H or SK PAR3H) or NordCon PC - supported software.
NORDAC SK 200E Manual 4.1.2 Configuration Changes to individual parameters are usually necessary for operation. (Exceptions: see Section 4.1.3 ) Configuration can be carried out to a limited extent via the DIP switches. Configuration by means of software parameterisation is necessary for more extensive parameter changes. NOTE Mixing of DIP switch configuration and (software) parameterisation should be avoided. 4.1.2.
4 Commissioning 4.1.2.2 DIP switch configuration The DIP switches provide the possibility of carrying out commissioning without additional control units. Additional settings are made using the potentiometer on the top of the frequency inverter. As supplied, all DIP switches are at the “Off” position, which corresponds to control via the digital inputs. The frequency setpoint value is adjusted via P1 and P2. No.

NORDAC SK 200E Manual 4.1.3 Commissioning examples 4.1.3.1 Test operation A SK 200E series frequency inverter which is to be used to control a 4-pole motor of the same power can be operated without any aids to testing purposes. The only condition for this is the correct connection of the mains and motor cables and the supply of a 24V DC control voltage to the inverter (See Section 4.1.1). The PTC input must be bypassed, if a motor with PTC is not available.
4 Commissioning Minimal configuration with options In order to implement completely autonomous operation (i.e. independent of control cables etc.) a Potentiometer Unit (SK CU4-POT) is required. In combination with an integrated mains unit (SK CU4-…-24V) a solution can be implemented with only one mains cable (1~ / 3~ according to the version), and a suitable speed and direction control can be ensured (See connection example below).
NORDAC SK 200E Manual 4.2 ATEX Zone 22 for SK 2x5E General information With appropriate modification, the NORDAC SK 2x5E frequency inverter can be used in explosion hazard areas. For this it is important that all the safety information in the operating instructions is strictly complied with for the prevention of personal injury and material damage. This is essential to prevent injury and damage.
4 Commissioning - ATEX 4.2.1 Modified SK 2x5E for compliance with Category 3D For the operation of an SK 2x5E in ATEX Zone 22 only a modified frequency inverter is permissible. This adaptation is only made at the NORD factory. In order to use the frequency inverter for ATEX Zone 22, the standard cable gland plugs must be replaced by ATEX-approved brass plugs. Also, in addition to modified seals, the clear plastic diagnostic plugs are replaced by aluminium/glass versions.

4 Commissioning - ATEX 4.2.2.3 Hand-held Technology Units for ATEX Zone 22 3D All hand-held technology units are not approved for continuous use in the ATEX Zone 22 3D. The may therefore only be used during commissioning or for maintenance purposes, if it is ensured that no explosive dust atmosphere exists.
NORDAC SK 200E Manual 4.2.2.5 Other options M12 sockets and plugs for installation in the terminal box of the basic device or in technology units may only be used of they are approved for use in ATEX Zone 22 3D.
4 Commissioning - ATEX 4.2.4 Commissioning information For Zone 22 the cable glands must at least comply with protection class IP 55. Unused openings must be closed with blank screw caps suitable for ATEX Zone 22 3D (minimum protection class IP 55). The motors are protected against overheating by means of the frequency inverter. This is carried out by the evaluation of the motor PTC by the frequency inverter.
