Safe and reliable: equipped with reverse polarity protection, short circuit protection, overload protection, protection level IP20, in compliance with international standards such as UL 508 and CSA 22.2.

Installation and wiring

1. Installation requirements

Installation method: Standard TH35 × 7.5/15 rail installation (EN 60715), UPS1600 needs to be installed vertically (input/output terminals facing downwards).

Installation gap: UPS1600 needs to reserve ≥ 50mm of heat dissipation space above and below, and UPS 1100 needs to reserve opening space above.

Environmental restrictions: Altitude ≤ 6000m (with a capacity reduction of 7.5% or 5K for every 1000m above 2000m), humidity of 5% -95%, no condensation.

2. Wiring specifications

Input wiring: IN+connected to 24V positive pole, IN - connected to 24V negative pole, wire specification 0.2-16mm ² (depending on model).

Output wiring: OUT+connected to the positive pole of the load, OUT - connected to the negative pole of the load, supporting no-load, overload, and short circuit protection.

Battery wiring: BAT+is connected to the positive pole of the battery, BAT - is connected to the negative pole of the battery, and up to 6 UPS 110 modules of the same model can be connected in parallel, with a maximum wire length of 3m.

Signal wiring: 14 pin signal connector, supporting functions such as buffer allowance, reset, battery communication, etc.

Configuration and Management

1. Configuration tool

Tool Name Applicable Scenarios Core Functions

SIMATIC STEP 7 (TIA Portal) Automation System Integration Hardware Configuration, Parameter Setting, Firmware Update, Diagnosis

SIMATIC STEP 7 (Classic Edition) Traditional PLC System Importing GSD Files, Parameter Assignment, Communication Configuration

SITOP UPS Manager local/remote management of device configuration, battery monitoring, alarm linkage, batch shutdown

Web server remote monitoring status viewing, alarm query, user management (supporting HTTPS)

2. Key parameter configuration

Buffer parameters: Switching threshold (21-25V, default 22.5V), buffer time (1-32767 seconds, default 60 seconds), stop buffer voltage (18-23V, default 18.5V).

Battery parameters: battery capacity, charging current (0.3A/0.8A/3A optional), faulty battery voltage (1-18V, default 6V).

Communication parameters: IP address, PROFINET device name, web server update interval (5-60 seconds, default 10 seconds).

3. Firmware update

Support updates through SIMATIC STEP 7, SITOP UPS Manager, and web server.

The firmware file needs to match the model (ups10a. upd/ups20a. upd/ups40a. upd), and the output will be turned off during updates. It is necessary to ensure stable power supply.

Maintenance and troubleshooting

1. Battery maintenance

Battery type: The UPS 110 uses maintenance free batteries and the 5Ah model is a LiFePo battery.

Replacement process: Turn off the power → Open the cover → Press the replacement button (≥ 2 seconds) → Remove the fuse → Replace the battery → Reset button → Insert the fuse → Close the cover.

Service life: about 4 years at 20 ℃, about 2 years at 30 ℃, and about 1 year at 40 ℃.

2. Common faults and their solutions

Fault type alarm text processing method

Battery defect: Check the battery voltage, fuse, and replace the faulty battery

Buffer mode not possible Check wiring, settings, battery voltage

Overcurrent reduces load, checks for short circuits, and automatically restarts after 20 seconds

Device temperature critical improves heat dissipation and removes unnecessary loads when the temperature is too high

3. Safety precautions

Only qualified personnel are allowed to operate, and the power supply must be disconnected and anti misoperation measures must be taken before installation.

When wiring, it is necessary to distinguish between positive and negative poles to avoid reverse connection and equipment damage.

During firmware updates, do not turn off the power, otherwise it may cause device failure.
