3.3.5 Grounding
Equipment grounding requirements must be checked in accordance with applicable regulations and standards before work
is started. The module frame or array must be grounded to avoid the hazards of electric shock or fire. The position of
possible grounding connections can be found in Fig. 3-1. An equipment grounding conductor can be fixed to the holes in the
frame (4 hole locations, each with 5.5mm diameter). A #12 AWG copper ground wire or equivalent should be used.
Observe all applicable regulations.
Follow the steps below for a correct grounding connection.
1. The copper wire with M5 cupped washer should be placed through the bolt;
2. Put the cut washer through the bolt , and the bolt must be put through the hole fixed in the aluminum frame;
3. Use the nut and cut washer to fix all the parts. The copper wire can not be attached to the aluminum.
4. Use a tightening torque around 210±20 N·cm.
4 Maintenance and care
Conergy PH modules are low-maintenance. However, Conergy recommends that you carry out a visual inspection and a
check of the mechanical and electrical connections for damage once a year. Dirt on the modules reduces the output and
the yield. If the photovoltaic modules are installed with an inclination angle of more than15°, they will generally be
adequately cleaned by rain.
Prevent damage to the module surface by scratching or extreme differences in temperature.
| Use only pH neutral liquid cleaners, even if there is excessive dirt build-up.
| Do not use abrasive cleaning agents.
| Ensure cleaning solutions are at roughly the same temperature as the module surface.
| Wipe the module surface with water and a soft cloth.
5 Removal
Risk of electric shock.
| Do not touch any bare electrical connection parts.
| Use only insulated tools.
1. Disconnect the inverter from the utility power on the AC side so that the photovoltaic system has no load.
2. Disconnect the photovoltaic system from the inverter at the cut-off point on the DC side.
3. Make sure that the system is not supplied with voltage.
4. Remove the photovoltaic system in the same way as it was installed; observe the safety instructions.
6 Disposal
Please ask your installer, dealer or Conergy, Inc. about disposal.
