2.1 Intended Use
The SMAString‑Monitor is a PV array junction box to which several strings can be connected in parallel. The SMAString-Monitor monitors the input currents of the strings and detects failures, thus helping to minimize power and yield losses.
The SMAString‑Monitor can be operated in large-scale PV power plants with central inverters from SMA Solar Technology AG or other PV inverters.
The maximum current values for the SMAString-Monitor must not be exceeded. The SMAString-Monitor should only be operated when the strings are fuse protected. SMA Solar
Technology AG guarantees safe operation of the SMAString-Monitor with inline fuse connectors as string fuses, providing that the inline fuse connectors are connected directly to the DC connectors of the string cables on the DC subdistribution. For any other type or location of the string fusing, SMA Solar Technology AG cannot guarantee safe operation of the SMAString-Monitor or compliance with the required thresholds. The inline fuse connectors are available as accessories.
The product is suitable for indoor and outdoor use. All work on the product must only be performed using appropriate tools and in compliance with the
ESD protection regulations. The installation of SMA accessories in the product is permissible without specific approval by SMA
Solar Technology AG, providing that the product supports the given SMA accessories (see Section14, page73).
The product must only be used in countries for which it is approved or released by SMA Solar Technology AG and the grid operator.

2.2 Safety Information
This section contains safety information that must be observed at all times when working on or with the product. To prevent personal injury and property damage and to ensure long-term operation of the product, read this section carefully and observe all safety information at all times.
Danger to life from electric shock due to live voltage
High voltages are present in the live components of the product. Touching live components results in death or serious injury due to electric shock.
• Wear suitable personal protective equipment for all work on the product.
• Do not touch any live components.
• Unless live voltage is absolutely necessary, always disconnect the product from voltage sources before performing any work (see Section8 "Disconnecting and Reconnecting", page47).
Danger to life from electric shock due to live DC cables
DC cables connected to PV modules that are exposed to sunlight are energized. Touching live cables results in death or serious injury due to electric shock.
• Prior to assembling the DC cables, ensure that the DC cables are voltage-free.
• Wear suitable personal protective equipment for all work on the product.
Danger to life from electric shock due to damaged product
Operating a damaged product can lead to hazardous situations that result in death or serious injuries due to electric shock.
• Only operate the product when it is in a flawless technical condition and safe to operate.
• Check the product regularly for visible damage.
• Make sure that all external safety equipment is freely accessible at all times.
• Make sure that all safety equipment is in good working order.
• Wear suitable personal protective equipment for all work on the product.
2 Safety
SMA Solar Technology AG
Operating Manual 9SSMUXX1015-BE-en-14
Danger to life from electric shock if the product is not locked
If the product is not locked, unauthorized persons will have access to live components carrying lethal voltages. Touching live components can result in death or serious injury due to electric shock.
• Always close and lock the product.
• Remove the keys.
• Store the keys in a safe place.
• Ensure that no unauthorized persons have access to the closed electrical operating area.
Danger to life from electric shock if the DC load-break switch is damaged
Switching the DC load-break switch at temperatures belowthe specified threshold may damage the DC load-break switch. The threshold is: ‒25°C. In this case, reliable disconnection can no longer be guaranteed.
If the DC load-break switch is switched in spite of visible damage, again the reliable disconnection function cannot be guaranteed.
High voltages are present in components that are not properly disconnected. Touching live components can result in death or serious injury due to electric shock.
• Do not switch the DC load-break switch at temperatures below the specified threshold. The threshold is: ‒25°C.
• Do not switch the DC load-break switch if it is visibly damaged.
Damage to the PV system due to incorrectly rated fuses
If fuses are incorrectly rated, excessive reverse currents can destroy the PV modules.
• Observe the maximum current values for the product when rating the fuses.

5 Mounting
5.1 Selecting the Mounting Location
Fire hazard due to wrong choice of mounting location
Despite careful construction, electrical devices can cause fires.
• Do not mount the DC sub-distribution on flammable construction materials.
• Do not mount the DC sub-distribution in areas containing highly flammable materials.
• Do not mount the DC sub-distribution in potentially explosive atmospheres.
Requirements for the mounting location:
☐ The mounting location can be outdoors or indoors. ☐ The mounting location must not be in a living or office area. ☐ The mounting location must not block any escape routes. ☐ The mounting location must be freely and safely accessible at all times without the necessity
for any auxiliary equipment (e.g. scaffolding or lifting platforms). Non-fulfillment of these
criteria may restrict servicing. ☐ The mounting location must be shaded, e.g. under a protective roof. ☐ The mounting location must be suitable for the weight and dimensions of the SMA
String‑Monitor. ☐ The mounting location must be suitable for the wind load. ☐ Mounting space below the SMAString-Monitor when using the inline fuse connectors:
at least 800mm.
Requirements for mounting the SMAString-Monitor
☐ Mount the SMAString-Monitor so that the connection area is facing downwards. ☐ Mount the SMAString-Monitor in a horizontal position. ☐ Do not mount the SMAString-Monitor in a twisted manner. ☐ Do not mount the SMAString‑Monitor in lying down or inclined position. ☐ An external cable support rail must be provided.
