Grounding Instructions
An equipment grounding conductor or a grounded, metal, and permanent wiring system is required for
the PCS connection. This should be run with circuit conductors and connected to the equipment
grounding bar or lead on the PCS.
Surge Arrester Safety
The function of lightning and surge protection systems is to protect the devices, functional isolations
and over voltage-sensitive consumer equipment of the 100kW PCS. The 100kW PCS is equipped with
a Type 2 Surge Arrester to cover the system when not placed directly in a lightning strike area.
Due to the wide energy voltage and frequency range of over voltage in lightning strike areas, it is
advisable to install a Type 1 Surge Arrester to augment the protection coverage around the user’s
switchboard.
WARNING!
Grounding: All input and output circuits are isolated from the enclosure (leakage current:
2.24 mA). System grounding, when by EN 62477-1 and AS 62040.1.1, is the responsibility of
the installer.

Location Considerations
To fully experience the benefits and reliability of the PCS design, follow the provided guidelines:
The PCS unit is rated IP55 and configured for outdoor installations.
Install the PCS in an accessible location following local requirements or European Standard for
enclosure and door clearances and proximity to other equipment.
For optimal PCS life and performance, do not mount the PCS in direct sunlight, especially in hot
climates. If the unit must be mounted in direct sunlight, a metal sun-shield is recommended but
not required.
The PCS is forced-air-cooled. The cabinet is separated into two compartments: front and rear
compartments.
In the case of front compartment, a heat exchanger is mounted on the front door and air is
drawn in by the heat exchanger fans through vents at the lower part of the front door, and
exhaust air is emitted from vents at the higher part of the front door, as shown in Figure 6.
From the rear compartment, air is drawn in through vents at the lower part of the rear door, and
exhaust air is emitted from vents in the front of the roof. The air inlet and outlet must not be
blocked, and the installation location should be sufficiently ventilated to prevent the PCS heat
output from increasing the ambient temperature beyond the PCS’s rating.

Installing the PCS Onsite
The PCS Series must be located in weather-proof enclosure or enclosed-area. The PCS is not
intended or designed for exposure to water or excessive dust.
The PCS system is designed to support the requirements of various environments.
The PCS must be in an upright position at all times.
The PCS functions at optimal operating performance if installed in a temperature range of -20°C
to 25°C (32°F to 77°F).
The specifications are available in “Specifications” on page 61.
Safety Considerations
The following safety information is intended to reduce the risk of accidents:
Keep the floor around the PCS clean to prevent metallic dust, iron or other metal filings from
being drawn inside the device, consequently causing short circuits.
Closed area installations:
The floors and surrounding area around the PCS must use non flammable material.
A portable powder fire extinguisher must be installed within easy reach of the PCS.
An automatic fire extinguishing system should be installed and enabled for the site.
Access to the installation site should be restricted to qualified service personnel.
Battery Ground Fault Concerns
The following are concerns surrounding potential risks of DC ground faults and the possible causes.
The primary concerns with any Battery Ground Fault include three principle areas:
1. Fire due to ground fault.
2. Risk to personnel due to ground or battery fault.
3. Risk to system reliability due to ground fault.
Causes of Battery Ground Faults
There are several causes for introducing a ground fault into a battery system. The following presents
the most common causes for ground faults.
Debris on the surface of the container- Dirt and debris on the surface of the battery can develop
paths for tracking to the battery rack.
Maintenance activities can place residual electrolyte on the container, which can enhance the
conduction path created by the debris exacerbating the level of ground fault.
Penetration in the container- issues such as cracks by stress or holes by penetration in the
container create an opportunity for electrolyte to seep out of the container and contact the
battery.
WARNING!
To prevent possible escalation into serious or catastrophic ground faults, make sure to equip
the corresponding Ground Fault Detection (GFD) equipment and follow strict maintenance
guidelines.
!

Installation
Installation Manual 16
To prevent possible ground fault risks, equip the corresponding GFD equipment. The battery warranty
may be null and void if the GFD equipment is not equipped.
All service and maintenance personnel must be trained in normal as well as emergency procedures.
Chain Hoist
The dimensions and weights specified must be taken into consideration when mounting the 100kW
PCS. All lifting equipment and lifting components (hooks, bolts, lifts, slings, chains, etc.) must be
properly sized and rated to safely lift and hold the weight of the 100kW PCS during the mounting
process.
Hoisting and Rigging Hazards
It is important that personnel involved with hoisting and rigging activities are trained in both safety and
operating procedures. Hoisting equipment should be operated only by trained personnel.
The cause of rigging accidents can often be traced to a lack of knowledge on the part of a rigger.
To prevent hoisting and rigging hazards, it is necessary for the operator to understand the following:
the weight of the load and rigging hardware
the capacity of the hoisting device
the working load limit of the hoisting rope, slings, and hardware.
When the weights and capacities are known, the rigger must then determine how to lift the load so that
it is stable.
Training and experience enable riggers to recognize hazards that can have an impact on a hoisting
operation.
be aware of elements that can affect hoisting safety, factors that reduce capacity, and safe
practices in rigging, lifting, and landing loads.
be familiar with the proper inspection and use of slings and other rigging hardware.
be aware of all the aspects of the lift and a means of communication has been agreed upon,
including what signals to be used, when the crane operator is working with a rigger or a rigging
crew.
WARNING!
The weight of the PCS is distributed on a small surface of the floor. It is necessary to verify
the floor load-bearing capacity.
