- The unit manual - The regulator installation guide. If any problem is noticed upon reception, immediately contact the transport company and/or CIRCUTOR's after-sales service. 1.2.- TRANSPORT AND HANDLING The transport, loading and unloading and handling of the unit must be carried out with proper precautions and using the proper manual and mechanical tools so as not to damage it. -
Page 7: Storage
OPTIM EMS-C series When unloading and moving the unit, use a forklift with forks long enough to support the entire length of the base. Otherwise, the forks should be long enough to support at least ¾ of said depth. The forks must be flat and supported firmly by the base. Raise the cabinet by placing the forks underneath the profile that supports the unit. -

Page 14: External Isolation And Protection Elements
OPTIM EMS-C series 3.6.- EXTERNAL ISOLATION AND PROTECTION ELEMENTS The capacitor bank has a manual internal four-pole isolator, but it must be connected to a line that is protected by a circuit breaker as well as earth leakage protection at the header, in ac- cordance with Spanish Low-Voltage Electrotechnical Regulations (LVR) and depending on the earthing system of the installation. -
Page 15: Current Transformer (Ct) Connection
OPTIM EMS-C series 3.9.- CURRENT TRANSFORMER (CT) CONNECTION A current transformer (CT) outside the capacitor bank must be installed to measure the total load current, plus that of the capacitor bank itself Figure 8 The standard transformer must have a nominal output of 5 A at the secondary. - Page 16 OPTIM EMS-C series Figure 9: Current transformer (CT) connection terminals. Once the cables are installed, disconnect the jumper connecting the S1 and S2 terminals of the capacitor bank ( Figure 10 Figure 10: Jumper for short-circuiting the secondary winding of the current transformer (CT).

Page 17: Static Capacitor Bank Start-Up
OPTIM EMS-C series 4.- STATIC CAPACITOR BANK START-UP 4.1.- BEFORE START-UP The static capacitor banks include a power factor regulator. Prior to start-up, the operation of said regulator must be known; for this reason, all capacitor banks come with the specific manual of the regulator being used. - Page 18 OPTIM EMS-C series 2.- Connect the power supply to the panel and check that the regulator display illuminates im- mediately. Otherwise, stop and check the previous step. 3.- Check the regulator's cos φ indication. If the indication is out of the 0.5 to 1 range, it may be possible that the current transformer and / or the power supply to the regulator are improperly connected.
