5.0 SAFETY

5.1 GENERAL WARNING

You must understand and follow all applicable local, state

and federal regulations in addition to standards for

building construction, electrical design, fire and safety.

Check with local authorities to determine applicable

permitting requirements before attempting to install or

maintain PV modules.

•Module interconnects pass direct current (DC) when

exposed to sunlight or other light sources.

•Contact with electrically active parts of the module,

such as terminals, can result in injury or death,

whether the module is connected or disconnected.

•Never wear metallic rings, watch bands, ear, nose or

lip rings or other metallic devices when installing or

trouble shooting a photovoltaic system.

5.2 MECHANICAL

•Rooftop PV systems should only be installed on

dwellings that have been formally analyzed for

structural integrity, and confirmed to be capable of

handling the additional weighted load of PV system

components including PV modules by a certified

building specialist or engineer. For your safety, do not

attempt to work on a rooftop until safety precautions

have been identified and taken, including without

limitation fall protection measures, ladders or

stairways, and personal protective equipment (PPE).

•For your safety, do not install or handle PV modules

under adverse conditions, including and without

limitation - strong or gusty winds and wet or frosted

roof surfaces.

•The flat-plate PV module construction consists of a

laminated assembly of solar cells encapsulated within

an insulating material with a rigid glass surface and an

insulated substrate. The laminated assembly is

supported by an aluminum frame that is also used for

mounting the module.

5.3 ELECTRICAL SHOCK HAZARD

•PV modules can produce current and voltage when

exposed to light of any intensity. Electrical current

increases with higher light intensity.

•DC voltage of 30 Volts or higher is potentially lethal.

Contacting the live circuitry of a PV system operating

under light can result in lethal electric shock.

•Use insulated tools and do not wear metallic jewelry

while working with PV modules.

In order to avoid arcing and electrical shock, do not

disconnect electrical connections under load.

•Faulty connections can also result in arcing and

electrical shock.

•Keep connectors dry and clean; ensure that they are in

proper working condition.

•Never insert metallic objects into the connectors, or

modify them in any way in order to secure an electrical

connection.

•Do not touch or handle PV modules with broken glass,

separated frames or a damaged back sheet unless the PV

modules are first disconnected and you are wearing

proper PPE.

•Avoid handling PV modules when they are wet unless

cleaning the PV modules as directed in this manual. See

12.2 Cleaning.

•Never touch electrical connections that are wet without

protecting yourself with insulated gloves. Artificially

concentrated light should not be directed on the module

or panel.

5.4 FIRE

•Mission Solar Energy modules have a Type 1, Class C fire

resistance rating in accordance with the IEC 61730 and UL

1703 standard.

•The fire rating of this module is valid only when mounted

in the manner specified in the mechanical mounting

instructions. See 9.0 Mechanical Installation

•PV modules are electricity generating devices that may

affect the fire safety of a building.

•The use of improper installation methods and/or defective

parts may result in the unexpected occurrence of an

electrical arc during operation.

•The recommended standoff height is no less than 150mm

(6 inches). If other mounting means are employed this

may affect the fire class ratings. A minimum slope of 5in/ft.

for installation over a roof is required to maintain the class

C fire rating. Modules must be mounted over a fire

resistant roof covering rated for the application.

•In order to mitigate the risk of fire in this event, PV

modules should not be installed near flammable liquids,

gases and/or locations with hazardous materials.

•In the event of a fire, PV modules may continue to produce

a dangerous voltage, even if they have been disconnected

from the inverter, have been partly or entirely destroyed,

or the system wiring has been compromised or destroyed.

•In the event of fire, inform the fire crew about the

particular hazards from the PV system, and stay away from

all elements of the PV system during and after a fire until

the necessary steps have been taken to make the PV

system safe.

6.0 OPERATING CONDITIONS

6.1 TEMPERATURE

All the modules must be mounted in environments that ensure they operate within the following maximum and

minimum operating temperatures.

•Maximum Operating Temperatures: +90oC (194oF)

•Minimum Operating Temperatures: -40oC (-40oF)

6.2 INSTALLATION CONDITION

Orient the module correctly. Mount the modules with the junction box in the uppermost position and hang the wires

downwards to avoid the ingress of water. For optimal module performance install PV modules facing true south in

northern latitudes and true north in southern latitudes. Shading will reduce electrical production. This installation is

applicable when the module is in portrait orientation. The modules have been evaluated by UL standards for mounting

using the recommended mounting positions.

7.0 UNPACKING & STORAGE

7.1 GENERAL INSTRUCTIONS

Store modules in an environment consistent

with prudent solar industry practices,

including, storage in dry conditions such that

modules

(or any part thereof) are not

immersed in water.

Do not carry the module above the head.

Do not allow children or unauthorized

persons near the installation site or storage

area of modules.

Do not drop or place objects such as tools on

the modules.

Do not use forklifts with less than 72 inch

forks to handle module pallet.

Do not mark the modules with sharp

instruments.

Unpack the module pallet with care and

follow the unpacking steps in this manual. Be

careful when

unpacking, transporting and

storing the modules.

Particular attention should be taken to avoid

8.0 UNPACKING

Prior to unpacking, ensure pallet is set

on a level surface and proper PPE is

equipped by all personnel. Proper PPE

for unpacking includes but is not limited

to eye protection, cut-resistant gloves

and steel-toe footwear.

Cut the two green strips of banding

material with scissors. These strips are

under high tension and will snap when

cut. Eye protection is highly

recommended.

Lift the pallet lid and set away from

unpacking area.

Using a box cutter, carefully cut along

the corner from the top to the middle of

the box on the packing slip side. Ensure

the blade stays on the outside and does

not cut through the white corner

protectors.

After both corners have been cut, fold

the lengthwise side of the box halfway

down allowing easy access to the

modules. Cut the internal banding

material as well being careful to avoid

contact with the modules.

Peel back sides of box to allow additional

access to modules.

(Optional) Apply no-residue tape across

the plastic corner clips to provide

additional support to stack as modules

are removed.

(Optional) Tape must reach at least 6

inches

down on opposite side of box to

maintain hold.

Remove white corner protectors.

Always wear Proper PPE when handling MSE Panels

(Optional) If tape has been used to

provide additional support to module

stack, peel tape back as needed to

remove individual modules.

The first module must be separated and

pulled out with additional care so as to

not scratch the modules. Continue

removing modules by peeling back tape,

moving the module forward and pulling

it up.

When four modules remain, the stack

will inherently become prone to tipping

over. At this point, ensure two

personnel are available to secure the

stack.

Slide the remaining modules to the

front of the box.

Carefully lower modules down to a

horizontal position with the glass side

down.

Remove box sleeve allowing easy access

to remaining modules from the

horizontal stack.

RELEASE DATE: 11/16/2016

PV Modules have been certified to IEC 61215 for a maximum static load on

the back of the module of up to 2400 Pa (i.e. wind load) and a maximum static

load on the front of the module of up to either 2400 Pa or 5400 Pa (i.e. wind

and snow load). For UL 1703 only, PV modules are tested to a front side and

rear side applied load based on 78 psf design load. The performance of solar

modules is defined on the uniform standard test conditions. These conditions

define performance at an incident sunlight of 1000 W/m2, a cell temperature

of 25oC (77oF) and an AM of 1.5 (AM = Air Mass). The air mass determines the

radiation impact and the spectral combination of the light arriving on the

earth’s surface.

For Bolt fitting, Module shall be bolted to support structures through four mounting holes using M7*16mm bolts

together with flat washer, spring washer and nut. The applied torque should be 16±2 Nm. For Clamp fitting, once the

module is aligned and centered, fully tighten the screws in the end-clamps in place to 16±2 Nm. All the end clamps

should be torqued to this value. Ensure that the channel nuts do not extend outside of the purlin. Drop the mid-clamp

into the purlin.

Place the channel nut inside purlin and place the grounding clip between the module and purlin with the grounding clip

tabs in the middle of the purlin. Install the final two end-clamps once the final module has been placed. Similar to the

End-Clamp section, place an end-clamp on each purlin, flush to the final module with the lip of the end-clamps on top of

the module. Fully tighten the end - clamps once they are properly placed. If the channel nuts extend outside of the purlin,

spacing has been done improperly and needs to be fixed.

Note: Allowable clamp minimum dimensions are as follows:

11.0 GROUNDING INSTRUCTIONS

A module with exposed conductive parts is considered to be in compliance with UL 1703 and IEC 61730 only when it is

electrically grounded in accordance with the instructions presented below and the requirements of the National Electric

Code. To reduce the possibility of electrical shock, ground the frame of the module or array before wiring the circuit

using a grounding method that meets NEC requirements for grounding solar electrical systems. In order to install,

Mission Solar Energy modules shall be grounded using grounding hardware that has been certified to meet requirements

for grounding systems in UL467, UL1703 or UL1741 on anodized aluminum frames. Mission Solar Energy recommends

one of the following methods of grounding the module frame. The attachment must be made in conformance with the

12.0 ELECTRICAL INSTALLATION

12.1 LOCAL / NATIONAL CODE AND

LOCAL REGULATION

To carry out installation, local regulations that may

apply should be taken into account such as NEC (USA)

or Canadian Electrical Code (Canada). Wiring should

be performed by a qualified and licensed

professional. Wiring should be protected to help

ensure personal safety and to prevent damage. All

modules connected in series should be of same model

number and/or same type. Do not connect modules

in parallel without using a combiner box or

equivalent.

Under normal conditions, a photovoltaic module is

likely to experience conditions that produce current

and/or voltage other than reported at standard test

conditions. The requirements of the National Electric

Code (NEC) in Article 690 shall be followed to address

these increased outputs. In installations not under

the requirements of the NEC, the values of ISC and

VOC marked on this module should be multiplied by

a factor of 1.25 when determining component

voltage ratings, conductor capacities, over current

device ratings and the size of controls connected to

the PV output.

12.2 WIRING

Mission Solar PV modules come with a factory

assembled Junction Box. Do not open the junction

box in any case. Wiring must be done in accordance

with local/national code and regulations; wear

protective gloves and shoes to avoid electric shock.

Address the following recommendations:

•The modules combined in parallel will produce a

specific current output. Each series string or

module is required to be fused. Table 1 describes

the maximum fuse size allowed.

•Do not connect the modules if the connectors are

wet.

•Be sure to put the cables away from sharp edges.

•If you need additional cables, you must use

exclusively solar cable of 12AWG/4mm2

minimum cross-sections, with ability to work in a

temperature range of at least -40oC and 90oC.

•Install the modules so that water from rain or

condensation cannot penetrate inside the cable

conduits.

•Fix cables to the structure so that the connectors

are protected from water ingress. Cables should

be held by UV resistant clamps or ties.

•To minimize possible effects of lightning induced

voltages, the surface of all conductive loops must

be as small as possible.

•Check that the wiring is correct before starting

the installation by verifying that the open voltage

is within expected values.

•Protect cables that could suffer mechanical

damage.

•Avoid direct sunlight on cables.

•Maximum series fuse rating 20A.

•Details for wiring in accordance with the NEC, and

that the grounding method of the frame of arrays

shall comply with the NEC, article 250.

•Installation shall be in accordance with CSA C22.1,

Safety Standard for Electrical Installations,

Canadian Electrical Code and Part 1.

•Modules may be connected in series (voltage

additive) and/or in parallel (current additive) to

produce the appropriate electrical output. When

connecting modules in parallel, each module (or

series string of modules so connected) shall be

connected according to the maximum series fuse

as specified.

•Recommended series connection of module open

circuit voltage should not exceed 80% limits range

of the system voltage and the fuse should be

connected at the end of each array.

•The installation instructions specify that

grounding is achieved through securement to the

array frame. The array frame must be grounded

in accordance with NEC Article 250.

12.3 CONNECTORS

•Keep connectors dry and clean. Ensure that connector caps are hand-tight before connecting the modules.

•Do not attempt to make an electrical connection with wet, soiled, or otherwise faulty connectors.

•Avoid sunlight exposure and water immersion of the connectors. Avoid allowing connectors to rest on the ground.

•Ensure cable connectors are UL and Canadian code complaint.

•Faulty connections can result in arcs and electrical shock.

•Check that all electrical connections are securely fastened.

•Make sure that all locking connectors are fully engaged and locked.

12.4 DIODES

•The junction boxes used with Mission Solar Energy modules contain bypass diodes wired in parallel with the PV cell

strings.

•In the case of partial shading, the diodes bypass the current generated by the non-shaded cells, thereby limiting

modules heating and performance losses. Bypass diodes are not over-current protection devices.

•Bypass diodes divert current from the cell strings in the event of partial shading. In the event of a known or suspected

diode failure, installers or maintenance providers should contact Mission Solar Energy.

•Never attempt to open the junction box.

13.0 MAINTENANCE

13.1 VISUAL INSPECTION

Mission Solar Energy recommends that PV systems be periodically inspected by the installer or other qualified personnel.

The purpose of the PV system inspection is to ensure that all system components are functioning properly. At a

minimum, this inspection should confirm the following:

•All cables and connector attachments are undamaged and properly secured.

•No sharp objects are in contact with the PV module surfaces.

•PV modules are not shaded by unwanted obstacles and/or foreign material.

•Mounting and grounding components are tightly secured with no corrosion.

•Defects should be addressed immediately.

13.2 CLEANING

•The dust accumulated on the front transparent substrate may reduce the power output, and may even cause

regional hot-spot effect.

•It’s usually not dangerous for the accumulated dust to reduce the sunshine because the light intensity is still

homogeneous and power reduction is not usually obvious.

•When modules are installed, avoid environmental influence factors that cast shadows and cover part or all of the

modules. This includes other modules, system support, bird drops, dust and so on. This debris may distinctly reduce

the power output.

•The cleaning frequency depends on the accumulation frequency and can vary from 6 months to 2 years. Do not use

alkaline, abrasive, alkali or acid materials, detergents, or cleaning solutions to clean the module.

•It is recommended to wipe the glass surface with a wet sponge or soft cloth. Please do not clean the glass with a

cleaning agent which contains acid or alkali.
