1. SAFETY STANDARDS
This user manual specifies installation and maintenance procedures, technical data and safety instructions for
SOCOMEC products. For further information visit the Socomec website: www.socomec.com.
The input and output circuits are isolated from the enclosure; the system grounding, when
required by Sections 690.41, 690.42, and 690.43 of the National Electric Code, ANSI/NFPA 70, is
the responsibility of the installer.
The wiring methods in accordance with the National Electrical Code, ANSI/NFPA 70 and
Canadian Electric Code (CEC) are to be used.
All national standards applicable to batteries must be observed.
CAUTION!
To reduce the risk of fire, connect only to a circuit provided with 170 amperes maximum branch-
circuit overcurrent protection in accordance with the National Electrical Code, ANSI/NFPA 70.
This inverter complies with Part 15 of the FCC Rules Operation so it must be able to handle any
interference and it must accept any interference received, including interference that may cause
undesired operation.
Overcurrent protection for the AC circuit is to be provided by others.
Before carrying out any operations read the interconnection manual and Battery Energy System
(BES) safety instructions carefully, in order to work under safe conditions.
If the Battery Energy System (BES) is not supplied by SOCOMEC, overcurrent protection for the
BES is to be provided by others.
NOTE!
Any work carried out on the equipment must be performed by skilled, qualified technicians.
NOTE!
Before carrying out any operations on the unit read the installation and operating manual care-
fully.
Keep this manual safe for future reference.
DANGER!
Failure to observe safety standards could result in fatal accidents or serious injury, and damage
equipment or the environment.
CAUTION!
If the unit is found to be damaged externally or internally, or any of the accessories are damaged
or missing, contact SOCOMEC.
Do not operate the unit if it has suffered a violent mechanical shock of any kind.
NOTE!
Install the unit in accordance with clearances in order to prevent access to handling devices and
guarantee sufficient ventilation (see Environmental requirements chapter).
NOTE!
Only use accessories recommended or sold by the manufacturer.
NOTE!
When the equipment is transferred from a cold to a warm place wait approx. two hours before
operating the unit.
DANGER! Live device! RISK OF ELECTRIC SHOCK!
SUNSYS PCS2IM is connected to two separately protected power supplies:
1) DC cable - BES power supply
2) AC cable - Power from the mains network, supplied by the electricity company
NOTE!
Before cleaning, performing maintenance work or connecting appliances to the unit, switch the
unit off and disconnect all power sources.

7EN
SUNSYS PCS2 IM UL Power Conversion System and Storage with Islanding Mode from 33 to 200 kVA - Ref.: IOMSUNPCXX07-EN 01
DANGER! Live device! RISK OF ELECTRIC SHOCK!
Carry out the following steps before SUNSYS PCS2IM maintenance:
- Disconnect the battery system’s main DC switch.
- Disconnect the AC power supplies.
- Disconnect the DC disconnection switches.
- Make sure the cable is fixed in position securely.
- Make sure the system cannot be restarted.
- Make sure the electricity supply (AC and DC voltages) has been disconnected.
- Cover or separate nearby live device units.
DANGER! RISK OF ELECTRIC SHOCK!
After disconnecting all power sources wait approx. 5 minutes for the complete discharge of the
unit.
CAUTION! RISK OF BURNS!
During operation the casing can reach high temperatures. Do not touch the surfaces!
NOTE!
Use AWG, 90 °C copper wire.
NOTE!
The tightening torque for DC and AC terminals must be 180 lb-in (20.3 Nm).
NOTE!
Any use other than the specified purpose will be considered improper. The manufacturer/supplier
shall not be held responsible for damage resulting from this. Risk and responsibility lies with the
system manager.

2. FOREWORD
Energy storage is the key solution to meeting the challenges of energy transition, using renewable energy and provid-
ing energy cost reductions for the following 4 main applications.
• Behind-the-Meter Energy Storage:
Reduce peak consumption and maximise PV energy self-consumption. SUNSYS PCS² (IM) can limit the impact
of increases in the electricity retail price by supplying the load to cut peak demand (peak shaving), maximising PV
energy self-consumption at building or community level. Any PV energy surplus is stored in the SUNSYS PCS² (IM)
battery system. This stored energy is used later to supply the load.
1
• PV plants:
Manage the intermittence of renewable energy production. SUNSYS PCS2(IM) ensures the production profile of an
intermittent renewable energy plant by limiting production to a predefined value, injecting energy to compensate for
solar variations, setting constant ramp-up or ramp-down.
